Airtac SAU Standard Air Cylinder SAU100X165S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X165S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 165mm 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 SAU100X165S
The AirTAC SAU100X165S is a double-acting profile-type cylinder built around an extruded aluminium barrel. It is engineered to be significantly shorter than an ISO 15552 cylinder of the same 100 mm bore, providing a space-saving footprint for heavy-duty machinery without sacrificing power. It delivers a robust 3927 N push force at 0.5 MPa, utilising a 25 mm carbon steel rod and a 1/2 inch air port.
Because this 165 mm stroke is a non-standard made-to-order length, it allows bespoke machine integration. For practical sizing, plan for a safe working load of about 2356 N (60% of the 0.5 MPa push) to account for seal friction and smooth travel. Vertically, this translates to lifting about 200 kg with a 2:1 safety margin. The included -S piston magnet enables CMSG, DMSG, or EMSG switches in the profile groove, and Viton H seals can extend operation up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X165S Is Used
Heavy Stamping Press
Drives a 150 kg lower die set into a hydraulic press, utilising the 3927 N push force at 0.5 MPa to seat heavy tooling firmly.
Pallet Dispenser Gate
Actuates a robust 165 mm stroke gate mechanism in an automated pallet line, where the compact profile saves valuable floor space.
Injection Mould Ejection
Pushes large moulded plastic parts out of a 100 mm bore injection machine, relying on the 1/2 inch port for rapid exhaust.
Is the Airtac SAU Standard Air Cylinder SAU100X165S the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm unit provides 3927 N. If you need even more force, there is no larger standard SAU bore, so you would look outside the series. This SKU includes the -S magnet for position sensing, and mounting is handled via AirTAC SC-series accessories like LB foot or FA flange. Remember that a standard cylinder drifts if air pressure drops; the adjustable 29 mm air cushions only decelerate the piston near stroke end, so fit an external rod lock or pilot-operated check valve if you must hold a load safely.
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 SAU100X165S FAQ
This 100 mm bore cylinder features a 1/2 inch air port and an M20x1.5 rod thread. It generates a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa the push force is 5497 N, and the theoretical maximum force is 801 kgf at 1.0 MPa.
Yes, the SAU100X165S shares its mounting dimensions with the AirTAC SC series, accepting LB, FA, and CA accessories. Because this model includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly into the extruded profile groove for position detection.
