About the Airtac SAI32 Standard Cylinder SAI32X280S
The AirTAC SAI32X280-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and 280mm stroke. It provides a push force of 402 N and a pull force of 345 N at 0.5 MPa. The extruded aluminum barrel design omits tie rods, offering a clean exterior that fits dimensionally into existing ISO 15552 mounting interfaces.
This specific configuration includes a magnetic piston (-S) for position sensing. It works seamlessly with CMSE or DMSE reed switches fitted into the sensor grooves on both sides of the barrel. The standard carbon steel piston rod provides reliable durability for general industrial automation tasks.

Where the Airtac SAI32 Standard Cylinder SAI32X280S Is Used
Compact Ejection
Ejects small machined parts from a fixture using a 280mm reach, relying on the 402 N push force to clear the work zone reliably.
Diverter Arm
Powers a lightweight diverter gate on a packaging line, using the magnetic piston to trigger CMSE sensors for stroke confirmation.
Carton Pushing
Transfers small cardboard cartons off a roller conveyor, where the 280mm stroke covers the full belt width.
Is the Airtac SAI32 Standard Cylinder SAI32X280S the Right Cylinder?
Choose this 32mm bore when your application requires around 402 N of push force at 0.5 MPa. If you need less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore yields 628 N. Because the 280mm stroke is substantial for a 32mm bore, side loads can cause rod-bearing bending. Use an external guide rail or a guided cylinder to prevent premature wear.
The SAI32X280-S is a direct replacement for any ISO 15552 cylinder with a 32mm bore, 280mm stroke, PT tapered port, and matching mounting accessories. Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not lock the load. If air pressure drops, the rod will drift. For position holding without live pressure, consider the SAIL variant with an air-released lock.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
