About the Airtac SAI32 Standard Cylinder SAI32AX55S
The AirTAC SAI32X55-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit is tailored for short-stroke cycling. Its extruded aluminum barrel omits tie-rods, providing a clean exterior that resists debris accumulation.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The integrated magnet (-S) enables direct mounting of CMSE or DMSE reed switches along the dual sensor grooves machined into both sides of the barrel. Fluid ports utilize a PT tapered thread design.

Where the Airtac SAI32 Standard Cylinder SAI32AX55S Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using its 402 N thrust capability.
Package Diverting
Provides rapid actuation for sorting small cartons on a packaging line with its 55 mm travel.
Clamping Mechanisms
Secures delicate workpieces during light machining, utilizing the precise positioning of the magnet-equipped piston.
Is the Airtac SAI32 Standard Cylinder SAI32AX55S the Right Cylinder?
When sizing this unit, consider stepping up to a 40 mm bore if your application requires the 628 N push force available at 0.5 MPa from the larger variant. The 55 mm stroke is optimal for high-cycle clamping or ejecting tasks. Because this is a double-acting pneumatic actuator, it relies on continuous air pressure to maintain position; the integrated adjustable air cushions only decelerate the piston at stroke ends and will not lock the load safely if air supply is lost. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other standard profile cylinders sharing the same 32 mm bore, 55 mm stroke, PT port, and LB/FA mounting dimensions.
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.
