Airtac SAU Standard Air Cylinder SAU100X205SH
The AirTAC Airtac SAU Standard Air Cylinder SAU100X205SH is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 205mm 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 SAU100X205SH
The AirTAC SAU100X205SH is a double-acting profile-type cylinder engineered for heavy-duty tasks, delivering a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Because it uses an extruded aluminum barrel rather than a bulky standard design, this 100 mm bore unit is physically shorter than an ISO 15552 cylinder of the same size, providing a clear spatial advantage in tight machine layouts. It features a 1/2 inch air port and a 25 mm rod with an M20x1.5 thread.
For real-world sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa, rather than relying on the maximum theoretical output. This equates to lifting roughly 200 kg vertically when applying a conservative 2:1 safety margin. The H designation indicates Viton FKM seals, extending the operating temperature range up to 150 C for high-heat environments. The built-in S magnet allows direct mounting of CMSG, DMSG, or EMSG switches along the profile groove for precise position detection.

Where the Airtac SAU Standard Air Cylinder SAU100X205SH Is Used
Injection Mold Clamping
Provides robust 3927 N push force to secure heavy injection mold halves within a compact machinery footprint, utilizing the high-temperature Viton seals to withstand ambient radiant heat up to 150 C.
Palletized Load Pusher
Executes a 205 mm stroke to index heavy palletized goods off a roller conveyor, safely moving loads approaching the 200 kg vertical-lift equivalent limit with smooth end-of-stroke deceleration.
Heavy Stamp Press Feed
Drives a thick-gauge metal blank into a stamping die, where the 1/2 inch port ensures adequate air volume for rapid actuation and the M20x1.5 rod thread secures the heavy tooling fixture.
Is the Airtac SAU Standard Air Cylinder SAU100X205SH the Right Cylinder?
When sizing this actuator, compare it against adjacent bores to match your pneumatic system capacity. Stepping down to the 80 mm bore reduces the push force to 2513 N at 0.5 MPa, while this 100 mm unit provides 3927 N. If your application demands even more power, note that this is the largest standard SAU bore available. For vertical or suspended loads, remember that a standard cylinder drifts when air pressure is lost or the valve is centered; the adjustable 29 mm air cushions only decelerate the piston near the end of stroke and do not function as a braking lock. To hold a load securely, integrate an external rod lock or a pilot-operated check valve into your circuit.
This 205 mm stroke falls well under the 1500 mm maximum standard stroke limit, keeping the assembly rigid without requiring auxiliary side-load guides. Mounting is highly versatile, sharing the exact same LB foot, FA flange, and CA clevis accessories as the AirTAC SC series. Ensure your control system utilizes the internal magnet for electronic sensor feedback.

- ✓ 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 SAU100X205SH FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa. Speed ranges from 30-800 mm/s.
No, it is not an ISO 15552 cylinder and does not share that footprint. However, it is physically shorter than an ISO cylinder of the same bore and uses the AirTAC SC-series mounting accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets. The included -S magnet allows you to mount CMSG, DMSG, or EMSG switches directly in the barrel groove.
