Airtac SAU Standard Air Cylinder SAU100X290
The AirTAC Airtac SAU Standard Air Cylinder SAU100X290 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 290mm stroke, 1/2" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAU Standard Air Cylinder SAU100X290
The AirTAC SAU100X290 is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is engineered to be noticeably shorter than an ISO 15552 cylinder of the same 100 mm bore, delivering a massive space saving in tight machinery layouts. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, operating at speeds of 30-800 mm/s.
Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensor switches. For practical sizing, plan for a safe working load of roughly 2356 N (about 60% of the 0.5 MPa push figure) to account for seal friction. Alternatively, it lifts about 200 kg vertically with a 2:1 safety margin. The unit features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at both ends.

Where the Airtac SAU Standard Air Cylinder SAU100X290 Is Used
Heavy-Duty Stamping
Drives a 150 kg press die in an automotive parts line, utilizing the 3927 N push force at 0.5 MPa to form steel brackets.
Pallet Lifting Gate
Actuates a heavy redirect gate on a conveyor system, safely lifting loads around 200 kg vertically with a 2:1 safety margin.
Injection Mold Clamp
Secures large plastic injection molds by providing sustained clamping pressure, taking advantage of the 7068 N push force at 0.9 MPa.
Is the Airtac SAU Standard Air Cylinder SAU100X290 the Right Cylinder?
When sizing this actuator, consider the neighboring bores to ensure optimal performance: stepping down to the 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. If your application demands even more power, note that 100 mm is the largest standard SAU bore available. For mounting, you can utilize standard AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises.
Remember that a standard cylinder does not maintain its position if air pressure is lost or the valve is centered; the piston will drift. The integrated air cushions only serve to decelerate the piston near the end of its stroke, not to lock the load. To securely hold a vertical load, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAU Standard Air Cylinder SAU100X290 FAQ
The SAU100X290 provides a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa it pushes 5497 N, and at 0.9 MPa it pushes 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore cylinder uses a 1/2 inch air port.
No, the SAU is not an ISO 15552 cylinder and is not dimensionally interchangeable, though it shares mounting accessories with the AirTAC SC series (LB, FA, FB, CA, CB). Additionally, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic sensors.
