Force and Application

Parameter Value
Extension effective area 1256 mm²; catalog rounded single-rod area
Extension at 0.5 MPa 628 N theoretical
Retraction effective area 1055 mm²; catalog rounded single-rod area
Retraction at 0.5 MPa 527.5 N theoretical

Theoretical axial force = effective area (mm²) × pressure (MPa), before friction/losses. Rod area reduces retraction area. Not safe working loads or guaranteed payloads.

Installation and Maintenance

Qualified personnel only. Before maintenance: secure loads, guard motion, isolate power/air and release residual pressure. Prevent unexpected restart motion; design for power/air loss.

Use clean, dry air filtered ≤40 µm; remove water, degraded oil and debris. Protect from dust, corrosion, coolant, weld spatter, vibration, heat and freezing; assess unusually dry air. Strong magnetic fields affect sensing.

Start unloaded; increase load gradually. Align rod/load; guide against side load, bending, impact and torque. Check long-stroke buckling, sag, support and air use. Rod joints do not replace guides.

Load-ratio guidance: ≤0.7 static/low speed; ≤0.5 at 50–500 mm/s; ≤0.3 above 500 mm/s. Not structural safety factors or payload guarantees; obey cylinder pressure/speed limits.

Fit flow controls at both ports; double action normally uses meter-out. Start closed; open gradually. Set cushions for load/speed without forcing screws. Heavy/fast loads may need an external absorber or deceleration circuit.

Compressibility/leakage defeat assumed precise prolonged closed-center stops or automatic multi-cylinder synchronization. Swing links need CA/CB/TC pivots, not rigid LB mounts forced through arcs. Match flange direction/support height to load.

Normally no added oil is needed. Once introduced, continuously use additive-free ISO-VG32 turbine oil. Oil-mist guide: ≤25 mg/m³; 0.5–5 drops per 1000 L. Size lubricator for flow; avoid excess/incompatible oil.

Clean pipes; keep sealant off leading threads. Start required tape 1.5–2 threads back. Verify tube pressure/temperature, OD/ID and bend radius. Hot spatter may require metal/flame-resistant tubing.

Protect sliding surfaces; periodically operate stored cylinders and prevent corrosion. Use the lowest cylinder/fitting/valve/tube/sensor/cable limit; temperature options do not raise other ratings.

PT1/4 mating piping-thread tightening reference: 6–8 N·m. This is not a G/NPT thread, TC clamp or sensor torque specification.

Electrical / physical reference Limits and conditions
DMSE two-wire 10–28 V DC; 2.5–100 mA load; ≤2.8 W; internal current ≤3 mA; residual voltage ≤3.5 V; leakage ≤0.06 mA.
DMSE NPN/PNP three-wire 5–30 V DC; switching ≤30 V and ≤200 mA, capacity ≤6 W; internal current ≤5 mA; residual voltage ≤0.7 V; leakage ≤0.01 mA.
CMSE reed two-wire 5–240 V AC/DC; meet both ≤100 mA and ≤10 W. Standard residual voltage ≤2.5 V at DC 100 mA; H has no indicator or residual voltage shown. No internal/leakage current or protection circuit shown.
Frequency, shock and temperature DMSE ≤1000 Hz with reverse-polarity/surge protection; CMSE ≤200 Hz. Both: 50 G shock reference. Standard −10–70 °C; CMSE-H −10–125 °C. Sensor H does not raise the cylinder, cable or connector rating.
E-profile body dimensions DMSE length 25, height 4.7 mm; CMSE length 26.8, height 5.3 mm. Both: cross-section width 6.3, upper width 5.2 mm.

Direct leads: 020/030/050/100 = 2/3/5/10 m. M08/M12: M8/M12 male, 0.5 m lead; M08010/020/030 and M12010/020/030: 1/2/3 m. Lead length is unrelated to stroke. Blank: two-wire; N/P: NPN/PNP.

DMSE standard/A05: IP64; W/A06: IP68. All CMSE: IP64. A05: flex-resistant robot cable; A06: oil-/flex-resistant. A05/A06: two-wire direct leads only, 19 mm minimum bend radius. No W quick-connector, A05/A06-W, CMSE-W, CMSE-A06 or A05-CMSE-H option is listed.

Match M8/M12 female leads: B two-wire/C three-wire. Pins: two-wire 1 brown (+), 4 blue (−), 3 unused; three-wire 1 brown (+), 3 blue (−), 4 black output. Direct leads need no quick cable. Cable temperature/IP/voltage ratings unspecified; sensor-body ratings do not rate the whole assembly.

Three-wire NPN: load between positive/black output; PNP: black output/negative. Check residual voltage/leakage for PLC inputs and series/parallel circuits. Simultaneous series sensing lights LEDs together; PLC compatibility is not universal.

Insert E-profile sensor in the matching groove, screw clear of the bottom face; position near the switching-range middle, then tighten. Recommended torque 0.15–0.20 N·m; maximum 0.25 N·m.

Connect correct load/supply before energizing; never place two-wire sensors across supply without load. Insulate leads; separate from high-voltage/power wiring. Prevent repeated strain, impact and strong magnetic interference.

Periodically check fixing, cables and indication. Waterproof does not guarantee prolonged immersion; protect from oil, chemicals, weld spatter, rapid temperature cycling and dense magnetic material.

H cylinder seals and CMS sensor H are separate options. SAI general range: −20 to 70 °C; full H-cylinder range is unestablished. Apply actual cylinder/sensor/cable/connector limits together.

Separate options; not an included kit or stock promise. Connect both SAI40 working ports with PT1/4 fittings/correct seals; check insertion depth, tool/rotation clearance, flow and tube loads. PT/G/NPT are not interchangeable. The M12×1.25 rod thread is not an air port.

Use suitable soft nylon/PU; match exact OD and compression-fitting ID. Where offered: D black, blank grey, -M miniature; -S specified stainless-304 parts, not an all-stainless cylinder/circuit. PHF has male RA/extra female RB of PT1/4; connect or permissibly seal RB, not a tube socket. Tees/Y/cross/distributors must not bridge chambers or unrelated controls.

Standard push-in fittings, direct/threadless controls and listed silencers: 0–1 MPa, −20–70 °C. BPC/BPOC: 0–0.9 MPa, 0–150 °C; SAI pressure path 0.15–0.9 MPa. BKC/BB/BD/BZ: 0–1 MPa, 0–150 °C; SAI pressure path 0.15–1 MPa. General cylinder −20–70 °C with 0–150 °C parts gives 0–70 °C or narrower. Apply lower valve/tube/sensor limits; component vacuum data do not rate a vacuum cylinder.

Install threads using the body hex, not locking nut; fully insert tube before tightening. BKC0806-02 accepts 8 × 5.5 or 8 × 6 mm; 8 × 5 mm needs BKC0805-02. BB/BD are same-standard adapters: BB male–male, BD male–female; table labels the other end. Match gender/size/flow; no cross-thread conversion. BZ closes permitted unused auxiliary ports only, never active cylinder ports.

Cylinder-end A controls thread→tube exhaust (meter-out), with free reverse supply; B controls tube→cylinder supply (meter-in). A is usual for double action; B needs a designed meter-in circuit. Start closed/open slowly. Closed leakage is allowed: not safety shutoffs. PTL caps on 1/4-port variants: adjustment reference: 0.16 N·m, not pipe-thread torque. Do not force caps/end stops. PSA/PSA-S/GPSA are metric tube-to-tube controls without A/B suffixes; match both ODs/check-throttle symbol. GPSA does not mean G thread.

Listed silencers serve separate valve exhaust: match thread/flow/backpressure. Not cylinder-port fittings, inlet filters or shutoffs. BESL adjustment changes backpressure. PPA6/8/10/12 have plain metric stems for matching sockets: POM body/cap, PE filter, 0–1 MPa, −20–70 °C; 25 dB at 0.5 MPa is a catalog test, not a site-noise promise. PPA has no D or thread suffix.

ASC20008: separate two-female-PT1/4-port inline control; needs male fittings. Follow P/A/check-throttle symbol. 0.05–0.95 MPa, −20–70 °C and 40 µm-or-finer filtered air; SAI pressure path 0.15–0.95 MPa before lower limits. Rated flow is not guaranteed cylinder speed.

GAFR20008S,GAFR30008S: separate upstream PT1/4 filter/regulator: 40 µm, PC bowl, differential/manual drain, bracket/round gauge, no reverse-flow valve. Inlet ≤1 MPa, setting 0.15–0.9 MPa, −5–70 °C non-freezing. Respect IN/OUT, flow/pressure loss, condensate, bowl environment and downstream limits. Not cylinder-mounted or a vacuum regulator.

US98A/UE95A examples: blue 100 m coils, not included cut lengths; 1 MPa at 23 °C with temperature derating: US98A −20–70 °C, UE95A −40–70 °C. Match OD/ID, bend radius, routing and flow; thinner low-pressure tubes are not equivalent. Only listed sizing diameters have the reference-speed association.

Separate Directional-Valve and Tube Examples

4A PT: single control 4A11006, 4A21006, 4A21008; double control 4A12006, 4A22006, 4A22008. 4V PT: single control 4V11006B, 4V21006B, 4V21008B; double control 4V12006B, 4V22006B, 4V22008B. 5V PT: single control 5V11006B050, 5V21006B050, 5V21008B050; double control 5V12006B050, 5V22006B050, 5V22008B050. All listed B versions use DC24V. 4V has DIN entry and internal pilot; 5V has 0.5 m leads (050) and internal pilot. 4A has single/double pneumatic control, external pilot supply and no coil. 4A configurations 20008: single control has one PT1/8 pilot port, double has two; confirm pilot threads on G versions.

10006 (PT: 4A/4V/5V): P/A/B/R/S 1/8; 20006 (PT: 4A/4V/5V): P/A/B/R/S 1/8; 20008 (PT: 4A/4V/5V): P 1/4, A/B 1/4, R/S 1/8. Ports use the assigned PT/G thread; select endpoints independently. Separate piped valve examples, not direct cylinder fittings or included parts. Operating range: 0.15–0.8 MPa, −20 to 70 °C, 40 µm filtration. Verify flow/load, pilot supply/exhaust backpressure; apply lower component limits.

PA6 nylon: 3 MPa at 23 °C, -10 to 70 °C; PA6060040100MBU: 6 × 4 mm, min. bend radius 45 mm. PA12 nylon: 2 MPa at 23 °C, -40 to 70 °C; PA12060040100MBU: 6 × 4 mm, min. bend radius 35 mm. UN54D flame-resistant tubing: 1 MPa at 23 °C, -20 to 70 °C; UN54D060040100MBU: 6 × 4 mm, min. bend radius 12 mm; UN54D080050100MBU: 8 × 5 mm, min. bend radius 18 mm; UN54D100065100MBU: 10 × 6.5 mm, min. bend radius 20 mm. All are blue 100 m coils; derate pressure above 23 °C. UN54D flame-resistant does not mean fireproof. Match exact OD, ID, tube compatibility and bend radius; PA6/PA12 sizes 8 × 5 and 10 × 6.5 mm are not established here.

M5 and 4M NAMUR have separate valve interfaces, not direct SAI mounts. No unverified direct adapter or complete kit is specified.

    FA/FB share a flange plate at different positions. CR requires CB. TC/FTC need the listed TCM1/TCM2: support size numbers may differ from bore. Confirm package and fasteners.

    TC is adjustable and separately orderable for this bore. Drawing-reference support centers: position for actual load.

    TC locking torque: 4–6 N·m; static holding-force reference: 1200 N, not cylinder thrust or payload. Above this, specify factory nonstandard fixed TC. Place bracket on barrel ledges and position it. Pre-tighten; check bracket and barrel sloping faces contact. 32/40: tighten 8 black screws through pre-, intermediate and final tightening.

    Drawing holes: LB 4 AP; FA/FB 4 BP; CR 4 K through-holes and 4 L counterbores; TCM1 4 E; TCM2 4 L through-holes and 4 K counterbores. CA DQ/CB CP tolerance: ±0.1 mm. Hole counts do not specify supplied fastener quantities.

    Magnet-ring reference GMED22X36.6X5
    Guide-ring reference SAI40 grooved wear-resistant guide ring associated with the magnet ring
    Cover references SAI40 front cover; SAI40 rear cover

    Confirm revision, dimensions, material and fit for these original service references; interchangeability is unverified. Cover names are not order codes; seal alternatives are not all fitted.

    Force and Application

    Parameter Value
    Extension effective area 1256 mm²; catalog rounded single-rod area
    Extension at 0.5 MPa 628 N theoretical
    Retraction effective area 1055 mm²; catalog rounded single-rod area
    Retraction at 0.5 MPa 527.5 N theoretical

    Theoretical axial force = effective area (mm²) × pressure (MPa), before friction/losses. Rod area reduces retraction area. Not safe working loads or guaranteed payloads.

    Installation and Maintenance

    Qualified personnel only. Before maintenance: secure loads, guard motion, isolate power/air and release residual pressure. Prevent unexpected restart motion; design for power/air loss.

    Use clean, dry air filtered ≤40 µm; remove water, degraded oil and debris. Protect from dust, corrosion, coolant, weld spatter, vibration, heat and freezing; assess unusually dry air. Strong magnetic fields affect sensing.

    Start unloaded; increase load gradually. Align rod/load; guide against side load, bending, impact and torque. Check long-stroke buckling, sag, support and air use. Rod joints do not replace guides.

    Load-ratio guidance: ≤0.7 static/low speed; ≤0.5 at 50–500 mm/s; ≤0.3 above 500 mm/s. Not structural safety factors or payload guarantees; obey cylinder pressure/speed limits.

    Fit flow controls at both ports; double action normally uses meter-out. Start closed; open gradually. Set cushions for load/speed without forcing screws. Heavy/fast loads may need an external absorber or deceleration circuit.

    Compressibility/leakage defeat assumed precise prolonged closed-center stops or automatic multi-cylinder synchronization. Swing links need CA/CB/TC pivots, not rigid LB mounts forced through arcs. Match flange direction/support height to load.

    Normally no added oil is needed. Once introduced, continuously use additive-free ISO-VG32 turbine oil. Oil-mist guide: ≤25 mg/m³; 0.5–5 drops per 1000 L. Size lubricator for flow; avoid excess/incompatible oil.

    Clean pipes; keep sealant off leading threads. Start required tape 1.5–2 threads back. Verify tube pressure/temperature, OD/ID and bend radius. Hot spatter may require metal/flame-resistant tubing.

    Protect sliding surfaces; periodically operate stored cylinders and prevent corrosion. Use the lowest cylinder/fitting/valve/tube/sensor/cable limit; temperature options do not raise other ratings.

    PT1/4 mating piping-thread tightening reference: 6–8 N·m. This is not a G/NPT thread, TC clamp or sensor torque specification.

    Electrical / physical reference Limits and conditions
    DMSE two-wire 10–28 V DC; 2.5–100 mA load; ≤2.8 W; internal current ≤3 mA; residual voltage ≤3.5 V; leakage ≤0.06 mA.
    DMSE NPN/PNP three-wire 5–30 V DC; switching ≤30 V and ≤200 mA, capacity ≤6 W; internal current ≤5 mA; residual voltage ≤0.7 V; leakage ≤0.01 mA.
    CMSE reed two-wire 5–240 V AC/DC; meet both ≤100 mA and ≤10 W. Standard residual voltage ≤2.5 V at DC 100 mA; H has no indicator or residual voltage shown. No internal/leakage current or protection circuit shown.
    Frequency, shock and temperature DMSE ≤1000 Hz with reverse-polarity/surge protection; CMSE ≤200 Hz. Both: 50 G shock reference. Standard −10–70 °C; CMSE-H −10–125 °C. Sensor H does not raise the cylinder, cable or connector rating.
    E-profile body dimensions DMSE length 25, height 4.7 mm; CMSE length 26.8, height 5.3 mm. Both: cross-section width 6.3, upper width 5.2 mm.

    Direct leads: 020/030/050/100 = 2/3/5/10 m. M08/M12: M8/M12 male, 0.5 m lead; M08010/020/030 and M12010/020/030: 1/2/3 m. Lead length is unrelated to stroke. Blank: two-wire; N/P: NPN/PNP.

    DMSE standard/A05: IP64; W/A06: IP68. All CMSE: IP64. A05: flex-resistant robot cable; A06: oil-/flex-resistant. A05/A06: two-wire direct leads only, 19 mm minimum bend radius. No W quick-connector, A05/A06-W, CMSE-W, CMSE-A06 or A05-CMSE-H option is listed.

    Match M8/M12 female leads: B two-wire/C three-wire. Pins: two-wire 1 brown (+), 4 blue (−), 3 unused; three-wire 1 brown (+), 3 blue (−), 4 black output. Direct leads need no quick cable. Cable temperature/IP/voltage ratings unspecified; sensor-body ratings do not rate the whole assembly.

    Three-wire NPN: load between positive/black output; PNP: black output/negative. Check residual voltage/leakage for PLC inputs and series/parallel circuits. Simultaneous series sensing lights LEDs together; PLC compatibility is not universal.

    Insert E-profile sensor in the matching groove, screw clear of the bottom face; position near the switching-range middle, then tighten. Recommended torque 0.15–0.20 N·m; maximum 0.25 N·m.

    Connect correct load/supply before energizing; never place two-wire sensors across supply without load. Insulate leads; separate from high-voltage/power wiring. Prevent repeated strain, impact and strong magnetic interference.

    Periodically check fixing, cables and indication. Waterproof does not guarantee prolonged immersion; protect from oil, chemicals, weld spatter, rapid temperature cycling and dense magnetic material.

    H cylinder seals and CMS sensor H are separate options. SAI general range: −20 to 70 °C; full H-cylinder range is unestablished. Apply actual cylinder/sensor/cable/connector limits together.

    GPSA tube-to-tube flow control 4 mm OD: GPSA4,GPSA4D; 6 mm OD: GPSA6,GPSA6D; 8 mm OD: GPSA8,GPSA8D; 10 mm OD: GPSA10,GPSA10D; 12 mm OD: GPSA12,GPSA12D

    Separate options; not an included kit or stock promise. Connect both SAI40 working ports with PT1/4 fittings/correct seals; check insertion depth, tool/rotation clearance, flow and tube loads. PT/G/NPT are not interchangeable. The M12×1.25 rod thread is not an air port.

    Use suitable soft nylon/PU; match exact OD and compression-fitting ID. Where offered: D black, blank grey, -M miniature; -S specified stainless-304 parts, not an all-stainless cylinder/circuit. PHF has male RA/extra female RB of PT1/4; connect or permissibly seal RB, not a tube socket. Tees/Y/cross/distributors must not bridge chambers or unrelated controls.

    Standard push-in fittings, direct/threadless controls and listed silencers: 0–1 MPa, −20–70 °C. BPC/BPOC: 0–0.9 MPa, 0–150 °C; SAI pressure path 0.15–0.9 MPa. BKC/BB/BD/BZ: 0–1 MPa, 0–150 °C; SAI pressure path 0.15–1 MPa. General cylinder −20–70 °C with 0–150 °C parts gives 0–70 °C or narrower. Apply lower valve/tube/sensor limits; component vacuum data do not rate a vacuum cylinder.

    Install threads using the body hex, not locking nut; fully insert tube before tightening. BKC0806-02 accepts 8 × 5.5 or 8 × 6 mm; 8 × 5 mm needs BKC0805-02. BB/BD are same-standard adapters: BB male–male, BD male–female; table labels the other end. Match gender/size/flow; no cross-thread conversion. BZ closes permitted unused auxiliary ports only, never active cylinder ports.

    Cylinder-end A controls thread→tube exhaust (meter-out), with free reverse supply; B controls tube→cylinder supply (meter-in). A is usual for double action; B needs a designed meter-in circuit. Start closed/open slowly. Closed leakage is allowed: not safety shutoffs. PTL caps on 1/4-port variants: adjustment reference: 0.16 N·m, not pipe-thread torque. Do not force caps/end stops. PSA/PSA-S/GPSA are metric tube-to-tube controls without A/B suffixes; match both ODs/check-throttle symbol. GPSA does not mean G thread.

    Listed silencers serve separate valve exhaust: match thread/flow/backpressure. Not cylinder-port fittings, inlet filters or shutoffs. BESL adjustment changes backpressure. PPA6/8/10/12 have plain metric stems for matching sockets: POM body/cap, PE filter, 0–1 MPa, −20–70 °C; 25 dB at 0.5 MPa is a catalog test, not a site-noise promise. PPA has no D or thread suffix.

    ASC20008: separate two-female-PT1/4-port inline control; needs male fittings. Follow P/A/check-throttle symbol. 0.05–0.95 MPa, −20–70 °C and 40 µm-or-finer filtered air; SAI pressure path 0.15–0.95 MPa before lower limits. Rated flow is not guaranteed cylinder speed.

    GAFR20008S,GAFR30008S: separate upstream PT1/4 filter/regulator: 40 µm, PC bowl, differential/manual drain, bracket/round gauge, no reverse-flow valve. Inlet ≤1 MPa, setting 0.15–0.9 MPa, −5–70 °C non-freezing. Respect IN/OUT, flow/pressure loss, condensate, bowl environment and downstream limits. Not cylinder-mounted or a vacuum regulator.

    US98A/UE95A examples: blue 100 m coils, not included cut lengths; 1 MPa at 23 °C with temperature derating: US98A −20–70 °C, UE95A −40–70 °C. Match OD/ID, bend radius, routing and flow; thinner low-pressure tubes are not equivalent. Only listed sizing diameters have the reference-speed association.

    Separate Directional-Valve and Tube Examples

    4A PT: single control 4A11006, 4A21006, 4A21008; double control 4A12006, 4A22006, 4A22008. 4V PT: single control 4V11006B, 4V21006B, 4V21008B; double control 4V12006B, 4V22006B, 4V22008B. 5V PT: single control 5V11006B050, 5V21006B050, 5V21008B050; double control 5V12006B050, 5V22006B050, 5V22008B050. All listed B versions use DC24V. 4V has DIN entry and internal pilot; 5V has 0.5 m leads (050) and internal pilot. 4A has single/double pneumatic control, external pilot supply and no coil. 4A configurations 20008: single control has one PT1/8 pilot port, double has two; confirm pilot threads on G versions.

    10006 (PT: 4A/4V/5V): P/A/B/R/S 1/8; 20006 (PT: 4A/4V/5V): P/A/B/R/S 1/8; 20008 (PT: 4A/4V/5V): P 1/4, A/B 1/4, R/S 1/8. Ports use the assigned PT/G thread; select endpoints independently. Separate piped valve examples, not direct cylinder fittings or included parts. Operating range: 0.15–0.8 MPa, −20 to 70 °C, 40 µm filtration. Verify flow/load, pilot supply/exhaust backpressure; apply lower component limits.

    PA6 nylon: 3 MPa at 23 °C, -10 to 70 °C; PA6060040100MBU: 6 × 4 mm, min. bend radius 45 mm. PA12 nylon: 2 MPa at 23 °C, -40 to 70 °C; PA12060040100MBU: 6 × 4 mm, min. bend radius 35 mm. UN54D flame-resistant tubing: 1 MPa at 23 °C, -20 to 70 °C; UN54D060040100MBU: 6 × 4 mm, min. bend radius 12 mm; UN54D080050100MBU: 8 × 5 mm, min. bend radius 18 mm; UN54D100065100MBU: 10 × 6.5 mm, min. bend radius 20 mm. All are blue 100 m coils; derate pressure above 23 °C. UN54D flame-resistant does not mean fireproof. Match exact OD, ID, tube compatibility and bend radius; PA6/PA12 sizes 8 × 5 and 10 × 6.5 mm are not established here.

    M5 and 4M NAMUR have separate valve interfaces, not direct SAI mounts. No unverified direct adapter or complete kit is specified.

    Circuit-Sizing Reference

    Theoretical reference speed Flow-area and tube reference
    300 mm/s 2 mm² effective flow area; 6 × 4 mm tube OD × ID
    400 mm/s 2.6 mm² effective flow area; 6 × 4 mm tube OD × ID
    500 mm/s 3.3 mm² effective flow area; 8 × 5 mm tube OD × ID
    600 mm/s 3.9 mm² effective flow area; 8 × 5 mm tube OD × ID
    700 mm/s 4.6 mm² effective flow area; 10 × 6.5 mm tube OD × ID
    800 mm/s 5.2 mm² effective flow area; 10 × 6.5 mm tube OD × ID

    Generic bore references, not measured SAI speeds. Flow area is not piston area or rated valve flow. Pressure/tube length/load are unspecified; the 0.5 MPa force example does not apply. Obey the 30–800 mm/s cylinder limit, actual valve/fitting/tube flow, cushions and exhaust backpressure. Similar nominal sizes do not make metric tubes fit inch sockets.

    Use the catalog above for dimensions, mounting drawings and symbol positions. Before installation, check full configuration, space and separately selected accessories.
