Airtac SAU Standard Air Cylinder SAU80X155
The AirTAC Airtac SAU Standard Air Cylinder SAU80X155 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 155mm 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 SAU80X155
The AirTAC SAU80X155 is a double-acting profile-type cylinder featuring a 155 mm stroke and a hard-anodized aluminum extruded barrel. Because it is more compact than a same-bore ISO 15552 unit, it saves valuable machine space. It delivers a robust 2513 N push force at 0.5 MPa, operating via a 3/8" port and a 25 mm rod with an M20x1.5 thread. This specific 155 mm stroke is a non-standard, made-to-order length.
For practical sizing, plan your payload around a safe working load of roughly 1508 N, which accounts for seal friction during smooth travel. If lifting vertically, this actuator can handle about 128 kg with a 2:1 safety margin. Note that this SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensor switches. For high-heat environments up to 150 C, specify the Viton H seal option instead of the standard TPU.

Where the Airtac SAU Standard Air Cylinder SAU80X155 Is Used
Stamping Press Feed
Pushes heavy gauge metal blanks into a stamping press, utilizing the 2513 N push force to overcome material friction in a confined fabrication cell.
Pallet Denester
Separates loaded pallets on a packaging line, where the compact profile length prevents interference with overhead conveyor structures.
Injection Mold Clamp
Actuates a secondary mold locking mechanism, providing reliable high-force clamping that safely releases when the primary hydraulic system retracts.
Is the Airtac SAU Standard Air Cylinder SAU80X155 the Right Cylinder?
When sizing, compare this 80 mm bore (2513 N push at 0.5 MPa) against the adjacent 63 mm bore (1559 N) or the 100 mm bore (3927 N) to match your exact payload. You can mount this actuator using AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, or CA/CB clevises, along with I, Y, F, or U rod knuckles. Because this SKU has no -S suffix, it is incompatible with magnetic position sensors.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centered; the adjustable 28 mm air cushions only decelerate the piston near stroke ends and do not function as a braking lock. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your 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 SAU80X155 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-800 mm/s, and it uses a 3/8" port.
No, it is not dimensionally interchangeable with ISO 15552 hardware. You must use AirTAC SC-series accessories like LB, FA, FB, CA, or CB mounts. Additionally, this specific SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG magnetic switches.
