About the Airtac SAI32 Standard Cylinder SAI32AX15S
The AirTAC SAI32X15-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 15mm stroke. Because this 15mm travel is shorter than the standard 25mm minimum, it is produced as a non-standard made-to-order stroke. It delivers 402N of push force and 345N of pull force at 0.5 MPa, making it well-suited for compact clamping and short ejection tasks.
Built with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this variant includes a built-in magnet for use with CMSE and DMSE sensor switches. The extruded aluminum barrel includes sensor grooves on both sides, and the cylinder relies on adjustable air cushions at both ends to decelerate the piston near stroke end.

Where the Airtac SAI32 Standard Cylinder SAI32AX15S Is Used
Short-Stroke Clamping
Ideal for compact fixtures where a 15mm stroke securely clamps small workpieces without requiring excessive space.
Part Ejection
Provides a fast 402N push at 0.5 MPa to eject small machined or molded parts from an automated line.
Sensor-Ready Sorting
The integrated magnet pairs with CMSE or DMSE switches for precise end-of-stroke detection in sorting gates.
Is the Airtac SAI32 Standard Cylinder SAI32AX15S the Right Cylinder?
When evaluating this 32mm bore, note that stepping up to a 40mm bore increases the 0.5 MPa push force to 628N, whereas dropping to a smaller bore is not standard within the ISO 15552 range. Because the 15mm stroke is non-standard, ensure your machine design accommodates this exact made-to-order length rather than assuming a catalog default.
This SAI32X15-S is dimensionally interchangeable per ISO 15552, meaning it serves as a direct replacement for other ISO 15552 profile cylinders. Remember that a standard double-acting cylinder does not hold its position if air pressure is lost; if your application requires dead-load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead.
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.
