Airtac SAU Standard Air Cylinder SAU80X115S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X115S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 115mm 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 SAU80X115S
The AirTAC SAU80X115S is a double-acting profile-type cylinder featuring an extruded aluminum barrel and a built-in magnet for position sensing. It generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. Because it uses a profile barrel instead of standard tie rods, it is significantly shorter than an ISO 15552 cylinder of the same bore, which saves valuable machine space. The 3/8" port and M20x1.5 rod thread handle high flow rates for rapid actuation.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction and smooth travel. In a vertical lift scenario with a 2:1 safety margin, this actuator lifts about 128 kg. The -S suffix means the piston carries a magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly into the barrel groove for precise end-of-stroke detection.

Where the Airtac SAU Standard Air Cylinder SAU80X115S Is Used
Injection Mold Clamping
Provides 2513 N of push force at 0.5 MPa to secure medium-sized injection mold halves, utilizing the compact profile length to fit within tight press boundaries.
Heavy Package Diverting
Uses the 115 mm stroke to push heavy automotive components off a main conveyor belt, with the built-in magnet confirming stroke completion via DMSG sensors.
Pallet Stopper Gate
Acts as a high-strength stopping gate on roller conveyors, absorbing pallet impacts with adjustable air cushions while maintaining a short overall envelope.
Is the Airtac SAU Standard Air Cylinder SAU80X115S the Right Cylinder?
When sizing this 80 mm bore, compare it against its neighbors to ensure you are not over-specifying. Stepping down to the 63 mm bore drops the push force to 1559 N at 0.5 MPa, while stepping up to the 100 mm bore increases it to 3927 N. This SAU80X115S fits perfectly when your application requires roughly 2513 N of push force. It shares its mounting footprint with AirTAC SC-series accessories, so you can use standard LB foot brackets, FA or FB flanges, and CA or CB clevises.
Because this is a double-acting cylinder, it relies on continuous air pressure to move and hold the rod. If air is lost or the control valve is centered, the piston will drift, and the adjustable 28 mm air cushions at both ends only decelerate the rod near the stroke limits rather than locking it in place. To suspend a load safely during an emergency stop, add an external rod lock or a pilot-operated check valve to 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 SAU80X115S 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. This model uses a 3/8" air port.
You cannot use ISO 15552 brackets, as the SAU is a distinct compact profile cylinder. It shares its mounting dimensions only with AirTAC SC-series accessories like LB, FA, FB, CA, and CB brackets. The -S suffix indicates a built-in magnet for mounting CMSG, DMSG, or EMSG sensors in the barrel groove.
