Airtac SAU Standard Air Cylinder SAU80X150S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X150S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 150mm 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 SAU80X150S
The AirTAC SAU80X150S is a double-acting profile-type cylinder featuring an extruded aluminum barrel that is significantly shorter than an ISO 15552 cylinder of the same 80 mm bore. It delivers a robust 2513 N of push force at 0.5 MPa, making it suitable for heavy-duty machinery. The 3/8" port and M20x1.5 rod thread ensure high flow and secure mechanical mounting for demanding industrial environments.
Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly into the profile barrel groove for precise end-of-stroke detection. For practical sizing, plan for a safe working load of about 1508 N (roughly 60% of the 0.5 MPa push force) to account for seal friction. In vertical setups, this translates to lifting about 128 kg safely with a 2:1 margin. If your application exceeds 70 C, you can specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X150S Is Used
Stamping Press Feed
Pushes heavy metal coils into a stamping press, utilizing the 2513 N push force at 0.5 MPa to overcome initial material friction.
Pallet Dispenser
Indexes empty pallets onto a packaging line, where the 150 mm stroke and 128 kg safe vertical lift capacity handle heavy wooden bases.
Injection Mold Clamp
Secures heavy mold halves during low-pressure clamping, relying on the 3/8" port for rapid actuation and the -S magnet for position feedback.
Is the Airtac SAU Standard Air Cylinder SAU80X150S the Right Cylinder?
When sizing this 80 mm bore, compare it against its neighbors: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N. Choose the SAU80X150S when your load requires the 2513 N intermediate thrust class. This model uses the same LB foot, FA/FB flange, and CA/CB clevis mounting accessories as the AirTAC SC series. Keep in mind that a standard cylinder drifts when air is lost or a valve is centered; the adjustable 28 mm air cushions only decelerate the piston near the stroke ends and do not function as a braking lock. 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 SAU80X150S FAQ
The 80 mm bore provides a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa, the push force is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. It features a 3/8" air port and a 25 mm piston rod.
No, it is not an ISO 15552 cylinder, but it shares the exact same mounting accessories as the AirTAC SC series, including LB, FA, FB, CA, and CB brackets. Additionally, the -S suffix means it has a built-in magnet for use with CMSG, DMSG, and EMSG sensors.
