Airtac SAU Standard Air Cylinder SAU80X165S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X165S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 165mm stroke, 3/8" 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 SAU80X165S
The AirTAC SAU80X165S is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is engineered to be shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, yielding a space advantage in tight machinery layouts. It operates with a 3/8" port, a 25 mm piston rod, and an M20x1.5 rod-end thread.
Operating at 0.5 MPa, this unit pushes with 2513 N and pulls with 2268 N. For practical sizing, plan for a safe working load of about 1508 N to account for seal friction and smooth travel. Vertically, it can lift roughly 128 kg with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet, enabling CMSG, DMSG, or EMSG electronic switches to seat directly into the profile groove for precise position sensing.

Where the Airtac SAU Standard Air Cylinder SAU80X165S Is Used
Automotive Panel Stamping
Drives a medium-heavy press fixture to clamp and form steel body panels, utilizing the 2513 N push force at 0.5 MPa to hold parts securely during the stamping cycle.
Palletized Goods Diversion
Pushes loaded pallets onto a secondary packaging conveyor line, where the compact profile length prevents the actuator from intruding into adjacent forklift traffic lanes.
Heavy Crate Elevation
Lifts industrial component crates weighing up to 128 kg vertically on a packaging elevator, relying on the built-in magnet to trigger precise upper and lower limit sensors.
Is the Airtac SAU Standard Air Cylinder SAU80X165S the Right Cylinder?
When sizing this actuator, evaluate the neighboring bores to match your exact force needs. Dropping down to a 63 mm bore lowers the push force to 1559 N at 0.5 MPa, while stepping up to a 100 mm bore increases it to 3927 N. Because this 80 mm bore pushes 2513 N at 0.5 MPa, it sits comfortably in the middle for medium-heavy handling.
The 165 mm stroke keeps the overall length short, but remember that a plain cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift. The adjustable air cushion at both ends only decelerates the piston near stroke end and acts as no brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. Mounting hardware matches the AirTAC SC series, allowing you to use LB foot brackets, FA/FB flanges, or CA/CB clevises.
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 SAU80X165S FAQ
This 80 mm bore cylinder features a 3/8" port and an M20x1.5 rod thread. The force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
No, it is not dimensionally interchangeable with ISO 15552 cylinders. Mounting accessories are compatible only with the AirTAC SC series (LB, FA, FB, CA, CB). However, the -S magnet allows you to use CMSG, DMSG, or EMSG switches directly in the profile barrel groove.
