| Sensor installation |
Detection requires an S magnetic piston; adding a sensor does not add a magnet |
| Cylinder reference weight |
17187 g; engineering reference estimate, not measured shipping weight |
Engineering weight estimate using the same-bore SAU basic-cylinder catalog mass and an equivalent extra-rod allowance at representative steel density. The adjusting mechanism and changed covers/internal parts are not separately mass-resolved. Seal-option mass differences are not quantified; this remains a default-material reference estimate. Mounts, rod-end joints, sensors, fittings and packaging are excluded. This is not an official SAUJ net mass or measured shipping weight, and no error bound is established. Actual supplied mass prevails; use the weighed assembly for handling and shipping.
Features and Operation
Airtac enterprise-standard double-rod double-acting cylinder with mechanical stroke adjustment. The compact profiled bidirectional piston seal retains oil. The aluminium barrel has no external tie rods, provides corrosion resistance and includes direct sensor grooves; magnetic sensing requires the S piston option. Adjust the pneumatic cushioning and select mounting for the moving load and end positions. Allow clearance for both rod ends and the adjustment mechanism; the two numeric values are nominal stroke and adjustment, not two independent powered stages. The catalogue also lists specially selected high-temperature seals for 150 °C service; this is not the rating of the current NBR (nitrile rubber) cylinder or attached components.
External and Mounting Dimensions
Dimensions are in mm except threads and angles. These are illustrated rod-end/body datums, not a guaranteed all-position swept envelope or packaged length. Confirm the mechanical adjustment, both rod clearances and attached-part space; the adjustment option is not a second powered stage.

Select LB or front FA as alternatives for the required mounting. Listed options do not imply included supply or quantity; confirm package contents and actual load capacity.
Rod ends use M20×1.5. MK is floating-joint angular compensation; PH is spherical-joint angle. Reference joint masses are not included in cylinder weight. Material categories do not identify every subcomponent or finish. Check alignment and mating threads; these M10-and-larger joints are outside the separate M6-and-smaller radial-offset note.
Numbered drawing parts are not complete service ordering codes. Confirm the full model, seal, production revision and genuine replacement number before ordering seal, guide, cover or adjustment-mechanism service parts.
Force and Application
| Parameter |
Value |
| Ideal pressure area, both directions |
4535.67 mm² = π / 4 × (80² − 25²) |
| Calculated force at 0.5 MPa, both directions |
2267.84 N |
| Calculation boundary |
Force (N) = pressure area (mm²) × pressure (MPa), before friction, exhaust backpressure and dynamic losses; not a guaranteed payload. |
| General load-ratio guidance |
≤0.7 static/low-speed; ≤0.5 at 50–500 mm/s; ≤0.3 above 500 mm/s within the 800 mm/s cylinder limit. These are selection guides, not payload guarantees. |
Both working sides have annular pressure area because a rod passes through each cover. A single-rod full-bore pushing-force table does not describe this structure.
Installation and Maintenance
Align the load and avoid side force, impact and rod-surface damage. Use independent guidance where needed. Guard moving parts; isolate air and electricity, vent pressure and secure loads before service or adjustment. Provide safe responses to supply loss and restart.
Keep piping clean and remove moisture and contamination. Protect against dust, droplets, oil and weld spatter; avoid freezing. Factory lubrication normally permits oil-free use; if oil is added, continue additive-free ISO VG32 turbine oil. Mist guide: ≤25 mg/m³ and 0.5–5 drops/1000 L; size the lubricator for actual flow.
Test without load, then increase load gradually. Start speed controls closed and open slowly; meter-out commonly stabilizes motion. Adjust cushioning for actual moving mass and speed without forcing the screw. The 28 mm nominal cushion reference is not additional travel or guaranteed effective deceleration distance for every short stroke.
Check mechanical stops, valve flow and exhaust backpressure. High kinetic energy may require separately engineered deceleration. Verify both rod-end clearances and cushion effectiveness after mechanical stroke adjustment.
PT3/8 piping-thread tightening reference: 8–10 N·m for the specified mating connection. This is not a G/NPT thread, sensor fastener or speed-control adjustment-cap torque. Match tube dimensions and threads; keep sealing debris out of air ports.

Separate options; no included-kit or stock promise. Connect both SAUJ80 working ports using PT3/8 fittings and the specified seal; check insertion depth, wrench/rotation clearance, flow and tube loading. PT/G/NPT are not interchangeable. The M20×1.5 rod thread is not an air port.
Use suitable soft nylon/PU tubing: exact OD, plus ID for compression. Where offered: D=black, blank=grey, -M=miniature. -S identifies specified stainless-304 parts, not an all-stainless assembly. PHF has male RA and extra female RB, both PT3/8; connect or seal RB as designed. RB is not a tube socket. Tees/Y/cross/distributors must not bridge chambers or unrelated controls.
Push-in fittings, direct/threadless controls and listed silencers: 0–1 MPa, −20–70 °C. BPC/BPOC: 0–0.9 MPa, 0–150 °C; SAUJ path 0.15–0.9 MPa. BKC/BB/BD/BZ: 0–1 MPa, 0–150 °C; SAUJ path 0.15–1 MPa. Using the general cylinder reference −20–70 °C, 0–150 °C parts limit the assembly to 0–70 °C or narrower. Obey lower valve/tube/sensor limits; component vacuum data do not rate the cylinder assembly.
Install threads with the body hex, not the locking nut; insert tubing fully before tightening. BKC0806-03 accepts 8 × 5.5 or 8 × 6 mm; 8 × 5 mm needs BKC0805-03. BB/BD use one thread standard: BB male–male, BD male–female; other ends are labelled in the table. Match its gender/size and flow; no cross-thread conversion. BZ closes permitted unused auxiliary ports only, never active cylinder ports.
At the cylinder, A meters thread→tube exhaust (meter-out), with free reverse supply; B meters 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, so these are not shutoffs. PTL caps on 3/8-port variants: adjustment reference: 0.24 N·m, not pipe-thread torque. Never force caps/end stops. PSA/PSA-S/GPSA are metric tube-to-tube controls, no A/B suffixes; match both ODs and the body check/throttle symbol. GPSA does not mean G thread.
Silencers: separate valve exhaust only. Match its actual thread, flow and backpressure; not cylinder-port fittings, inlet filters or shutoffs. BESL adjusts backpressure. PPA6/8/10/12 use plain metric stems in matching sockets: POM body/cap, PE filter, 0–1 MPa, −20–70 °C; 25 dB at 0.5 MPa is a catalog test, not an onsite noise promise. PPA has no D or thread suffix.
ASC30010: separate two-female-PT3/8-port inline control; needs male fittings. Follow P/A and the check/throttle symbol. 0.05–0.95 MPa, −20–70 °C and 40 µm-or-finer filtered air; SAUJ path 0.15–0.95 MPa before lower limits. Rated flow does not guarantee cylinder speed.
GAFR30010S,GAFR40010S: separate upstream PT3/8 filter/regulator, 40 µm element, PC bowl, differential/manual drain, bracket and 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 all downstream limits; not a cylinder fitting or vacuum regulator.
US98A/UE95A examples: blue 100 m coils, not supplied cut lengths. Rated 1 MPa at 23 °C, temperature derating required: US98A −20–70 °C, UE95A −40–70 °C. Match OD/ID, bend radius, routing and flow; thinner low-pressure tubes are not equivalent. Tube sizes are component examples; calculate actual SAUJ flow independently.
Separate Directional-Valve and Tube Examples
4A PT: single control 4A31010; double control 4A32010. 4V PT: single control 4V31010B; double control 4V32010B. 5V PT: single control 5V31010B050; double control 5V32010B050. 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 30010: single control has one PT1/8 pilot port, double has two; confirm pilot threads on G versions.
30010 (PT: 4A/4V/5V): P 3/8, A/B 3/8, R/S 1/4. Port dimensions use the PT/G thread assigned above; choose each endpoint independently. These separately piped valve examples are not direct cylinder fittings or included parts. Operating range: 0.15–0.8 MPa, −20 to 70 °C, 40 µm filtration. Confirm flow, load, pilot supply and exhaust backpressure; apply all lower component limits.
UN54D flame-resistant tubing: 1 MPa at 23 °C, -20 to 70 °C; UN54D100065100MBU: 10 × 6.5 mm, minimum bend radius 20 mm. US98A tubing: 1 MPa at 23 °C, -20 to 70 °C; US98A160110100MBU: 16 × 11 mm, minimum bend radius 80 mm; burst reference 3 MPa at 23 °C is not working pressure; reference mass 10.03 kg/100 m. 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 references have their own valve connections and are not direct SAUJ mounting accessories. No unverified direct adapter or complete kit is specified.
The 16 × 11 mm tube is documented, but a complete 16 mm fitting/control connection path is not established here. Do not substitute smaller fittings or infer another tube ordering code.
SAUJ has two working air ports. Select circuit flow using its annular pressure area in both directions, actual load, adjusted travel, piping losses and exhaust backpressure. A general bore-based selection chart does not guarantee an achieved SAUJ speed or establish a directly mounted valve assembly.
