About the Airtac SAI32 Standard Cylinder SAI32AX140S
The AirTAC SAI32X140-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. It delivers a push force of 402 N at 0.5 MPa across its 140 mm stroke, making it well suited for light-duty positioning and clamping tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies machine integration.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance in humid environments. The -S suffix denotes an integrated magnet, allowing seamless position detection with CMSE or DMSE series switches mounted directly into the dual sensor grooves. Fluid supply connects via a PT tapered G1/8 port.

Where the Airtac SAI32 Standard Cylinder SAI32AX140S Is Used
Small Part Ejection
Provides the 402 N output needed to push light machined components out of a fixture on an automated lathe.
Package Diverting
Actuates a routing flap on a packaging line, using the 140 mm stroke to redirect small boxes efficiently.
Sensor Actuation
Uses the integrated magnet to trigger CMSE switches for end-of-stroke confirmation in a compact assembly station.
Is the Airtac SAI32 Standard Cylinder SAI32AX140S the Right Cylinder?
Choose the 32 mm bore when a 20 mm bore lacks the necessary thrust and a 40 mm bore (which yields 628 N at 0.5 MPa) is physically too large for your envelope. The 140 mm stroke provides ample travel for ejecting parts or actuating small grippers. Because this is a 140 mm stroke, side-load stress on the rod bearing is moderate, but always ensure the load is guided linearly to prevent premature seal wear.
This SAI32X140-S is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders with matching 32 mm bore and 140 mm stroke specifications. It features a PT G1/8 port, a M10x1.25 rod thread, and adjustable air cushions at both ends. Note that the standard double-acting design relies on continuous air pressure to hold position; if your application requires dead-stop holding without air, consider the SAIL locking variant or an external pilot-operated check valve.
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.
