About the Airtac SAI32 Standard Cylinder SAI32X55S
The AirTAC SAI32X55-S is a double-acting ISO 15552 profile cylinder offering 402 N of push force and 345 N of pull force at 0.5 MPa. Its 55 mm stroke is a made-to-order dimension, providing exact motion control for compact assembly machinery where standard 50 mm or 75 mm strokes are unsuitable.
This unit includes a standard magnet for proximity sensing, utilizing the dual sensor grooves machined into the extruded aluminum barrel to accept CMSE or DMSE reed switches. The piston rod is constructed from carbon steel, and the seals are standard TPU, ensuring dependable operation within the -20 to +70 C temperature range.

Where the Airtac SAI32 Standard Cylinder SAI32X55S Is Used
Component Clamping
Ideal for securing small electronic components or machined parts during light drilling or fastening, utilizing its 402 N push force within a compact 55 mm stroke envelope.
Package Diverting
Provides rapid actuation for sorting arms or pop-up gates on conveyor lines, where the integrated magnet allows precise end-of-stroke detection for timing.
Small Press Ejection
Suitable for ejecting lightweight molded or stamped parts from small presses, offering a compact footprint and reliable double-acting return.
Is the Airtac SAI32 Standard Cylinder SAI32X55S the Right Cylinder?
Selecting this 32 mm bore is optimal when your application requires a push force around 402 N at 0.5 MPa. If your process demands greater thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa, while dropping down to a smaller profile cylinder would reduce the footprint but sacrifice thrust. Because the 55 mm stroke is non-standard, expect a made-to-order lead time.
As a true ISO 15552 profile cylinder, it provides a direct replacement for any standard 32 mm bore, 55 mm stroke, G1/8 ported cylinder with PT threads. Since this is a double-acting cylinder, it relies on continuous air pressure to hold position; exhausting the air or centering the valve will cause the piston to drift. For applications requiring position holding without live pressure, 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.
