Airtac SAU Standard Air Cylinder SAU100X90S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X90S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 90mm 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 SAU100X90S
The AirTAC SAU100X90S is a double-acting profile-type cylinder featuring a 100 mm bore and a 90 mm stroke. Its extruded aluminum barrel makes it shorter and more compact than a standard ISO 15552 cylinder of the same bore, providing a distinct space advantage in tight machinery layouts. Operating at 0.5 MPa, it generates a push force of 3927 N and a pull force of 3681 N, placing it firmly in the heavy-duty class.
Because this SKU includes the -S magnet, it readily accepts CMSG, DMSG, or EMSG electronic switches in the profile groove for position sensing. For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. Alternatively, you can expect it to lift roughly 200 kg vertically with a 2:1 safety margin. The unit uses a 1/2" air port, an M20x1.5 rod thread, and a 29 mm adjustable air cushion at each end to decelerate the piston smoothly.

Where the Airtac SAU Standard Air Cylinder SAU100X90S Is Used
Heavy Stamping Presses
Provides robust clamping with 3927 N of push force at 0.5 MPa to hold thick metal sheets securely in place during aggressive stamping operations.
Pallet Transfer Stops
Acts as a high-strength stop gate on heavy-duty packaging conveyors, reliably halting fully loaded wooden pallets without bouncing back.
Automated Guided Vehicles
Drives the vertical lifting forks on automated guided vehicles, safely elevating components weighing up to 200 kg using a 2:1 safety margin.
Is the Airtac SAU Standard Air Cylinder SAU100X90S the Right Cylinder?
When sizing this model, consider the neighboring bores: dropping down to an 80 mm bore reduces the push force to 2513 N at 0.5 MPa, while stepping up is not possible as 100 mm is the largest available SAU bore. This SAU100X90S shares its mounting footprint with AirTAC SC-series accessories, allowing you to use LB foot mounts, FA/FB flanges, or CA/CB clevises. Keep in mind that a plain cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; the air cushion only decelerates the piston near the stroke end and acts as neither a lock nor a brake. For suspended loads, integrate an external rod lock or a pilot-operated check valve.
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 SAU100X90S FAQ
This 100 mm bore cylinder features a 1/2" air port and an M20x1.5 rod thread. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, a push force of 5497 N at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder and is not dimensionally interchangeable with ISO standards. It is a compact profile cylinder that shares mounting accessories specifically with the AirTAC SC series, such as LB foot, FA/FB flange, and CA/CB clevis mounts.
