About the Airtac SAI32 Standard Cylinder SAI32X40S
The AirTAC SAI32X40-S is a double-acting ISO 15552 profile cylinder offering a compact 40mm stroke. It delivers 402N of push force at 0.5 MPa, making it well-suited for short-travel clamping and ejection tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists contamination.
Equipped with a magnetic piston (-S), this unit supports CMSE and DMSE reed switches via sensor grooves on both sides of the barrel. The standard carbon steel piston rod ensures rugged durability for high-cycle automated machinery.

Where the Airtac SAI32 Standard Cylinder SAI32X40S Is Used
Part Ejection
Ideal for pushing finished parts out of a machining fixture with precise 40mm travel.
Package Diverting
Provides rapid sorting force on conveyor lines where a 32mm bore provides sufficient thrust.
Small Clamps
Secures light workpieces during assembly or welding operations within confined machinery.
Is the Airtac SAI32 Standard Cylinder SAI32X40S the Right Cylinder?
Select this 32mm bore when an application requires less force than the 40mm version (which provides 628N at 0.5 MPa) but still needs robust actuation. The 40mm stroke is optimal for tight spaces where a standard 25mm stroke falls short. Because this is a double-acting cylinder, it relies on continuous air pressure to maintain position; if you need fail-safe load holding, consider the SAIL variant with an air-released lock.
This model features a PT tapered port thread and a G1/8 port size. It serves as a dimensionally interchangeable direct replacement for any standard ISO 15552 cylinder with a 32mm bore and 40mm stroke, utilizing standard FA/FB flange or TC trunnion mounting accessories.
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.
