| Sensor installation |
Detection requires an S magnetic piston; adding a sensor does not add a magnet |
| Cylinder reference weight |
16924 g; catalogue reference, not measured shipping weight |
Catalogue reference mass: 2495 g non-stroke mass + 1503 mm × 9.6 g/mm, rounded to the nearest gram. The N seal mass difference is not independently specified. Mounting, rod-end and other accessory masses and packaging are excluded; this is not a measured shipping weight. Actual supplied mass prevails.
Features and Operation
Airtac enterprise-standard single-rod double-acting cylinder. 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. The catalogue describes a shorter same-bore SAU body than ISO15552 cylinders; this is a length comparison, not an ISO conformity or universal interchangeability claim. 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.

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 extending / retracting pressure area |
7853.98 / 7363.11 mm² |
| Calculated extending / retracting force at 0.5 MPa |
3926.99 / 3681.55 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. |
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 29 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. Allow space for the extending rod and attached load.
PT1/2 piping-thread tightening reference: 12–15 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 SAU100 working ports using NPT1/2 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.
Discontinued families are historical service references; confirm availability or an approved replacement before ordering.
Use suitable soft nylon/PU tubing: exact OD, plus ID for compression. Inch tube sizes are exact: 1/4 = 6.35, 5/16 = 7.9375, 3/8 = 9.525 and 1/2 = 12.7 mm; do not substitute nominal metric sizes. NPHF has male RA and extra female RB, both NPT1/2; 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. NBPC: 0–1 MPa, 0–150 °C; SAU path 0.15–1 MPa. NBKC/NBB/NBD/NBZ: 0–1 MPa, 0–150 °C; SAU 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. NBPC does not share the metric BPC 0.9 MPa limit.
Install threads with the body hex, not the locking nut; insert tubing fully before tightening. The printed 1/3 in compression ID is literal; do not round it to a metric tube. NBB/NBD 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. NBZ 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. NPTL caps on 1/2-port variants: limit: 0.32 N·m, not pipe-thread torque. Never force caps/end stops. NPSA is an inch tube-to-tube control without A/B suffixes; match both ODs and the body check/throttle symbol.
Silencers: separate valve exhaust only. Match its actual thread, flow and backpressure; not cylinder-port fittings, inlet filters or shutoffs. NBESL adjusts backpressure.
ASC30015T: separate two-female-NPT1/2-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; SAU path 0.15–0.95 MPa before lower limits. Rated flow does not guarantee cylinder speed.
GAFR30015ST,GAFR40015ST: separate upstream NPT1/2 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.
Match specified inch tubing and both endpoint fittings. Metric coils, PSA/GPSA and PPA are not specified for inch sockets. Coil length and tubing pressure/temperature must suit the actual circuit.
A 16 × 11 mm reference tube needs separately specified 16 mm endpoint fittings and controls; the listed inch sockets do not make that connection.
Separate Directional-Valve and Tube Examples
4A PT: single control 4A31010, 4A41015; double control 4A32010, 4A42015. 4A G: single control 4A31010G, 4A41015G; double control 4A32010G, 4A42015G. 4V PT: single control 4V31010B, 4V41015B; double control 4V32010B, 4V42015B. 4V G: single control 4V31010BG, 4V41015BG; double control 4V32010BG, 4V42015BG. 5V PT: single control 5V31010B050, 5V41015B050; double control 5V32010B050, 5V42015B050. 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 30010/40015: single control has one PT1/8 pilot port, double has two; confirm pilot threads on G versions.
30010 (G: 4A/4V; PT: 4A/4V/5V): P 3/8, A/B 3/8, R/S 1/4; 40015 (G: 4A/4V; PT: 4A/4V/5V): P/A/B/R/S 1/2. 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.
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. 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 SAU mounting accessories. No unverified direct adapter or complete kit is specified.
The listed PT/G valves are separate circuit references, not NPT valve variants. The metric tube examples do not fit the listed inch sockets; select a separately verified complete inch-tube path.
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.
SAU has two working air ports. Select circuit flow using its full-bore extension area and annular retraction area, actual load, travel, piping losses and exhaust backpressure. A general bore-based selection chart does not guarantee an achieved SAU speed or establish a directly mounted valve assembly.
