About the Airtac SAI32 Standard Cylinder SAI32X55
The AirTAC SAI32X55 is a double-acting ISO 15552 profile cylinder offering 402 N of push force at 0.5 MPa. Its 55 mm stroke makes it highly suitable for compact clamping and short linear actuation tasks where space is strictly limited.
This variant features a standard carbon steel piston rod and PT tapered port threads. It includes an extruded aluminum barrel with sensor grooves on both sides, allowing easy mounting of CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI32 Standard Cylinder SAI32X55 Is Used
Small Part Clamping
Ideal for securing small electronic components or plastic housings during machining or assembly operations.
Package Diverting
Provides the rapid extend and retract motion needed for lightweight package sorting gates on conveyor lines.
Valve Actuation
Serves as a reliable pneumatic actuator for opening and closing small process valves in localized machinery.
Is the Airtac SAI32 Standard Cylinder SAI32X55 the Right Cylinder?
If your application requires less force, stepping down is not an option as 32 mm is the smallest SAI bore, but you can step up to the 40 mm bore for 628 N at 0.5 MPa if margins are tight. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal.
This 32 mm bore uses a G1/8 port with PT threads and standard LB or FA mountings. Note that a standard cylinder will drift if air pressure is lost; for position holding without live pressure, consider the SAIL locking variant or an external rod lock.
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.
Airtac SAI32 Standard Cylinder SAI32X55 FAQ
