About the Airtac SAI32 Standard Cylinder SAI32AX450
The AirTAC SAI32X450 is a double-acting ISO 15552 profile cylinder engineered for direct interchangeability with other standard 15552 units. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore model utilizes a 450 mm stroke to drive medium-duty linear motion tasks.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It features PT tapered port threads and operates without a magnet, meaning direct position sensing is not supported on this unit.

Where the Airtac SAI32 Standard Cylinder SAI32AX450 Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using the 450 mm stroke, relying on the SUS420J2 rod to resist humidity in packaging facilities.
Light Assembly Press
Provides a consistent 402 N push at 0.5 MPa to seat bearings or pins into housings without marring the component surface.
Pallet Handling Gate
Actuates a lightweight routing gate for pallet conveyors, where the PT ported air connections ensure secure, leak-free pneumatic fittings.
Is the Airtac SAI32 Standard Cylinder SAI32AX450 the Right Cylinder?
When sizing this actuator, consider that stepping up to the 40 mm bore yields 628 N at 0.5 MPa if your application demands more push force. Because the 450 mm stroke creates a long unsupported rod extension, side loads can cause severe rod-bearing bending and premature seal wear. Implement an external guide rail or switch to a guided cylinder to absorb lateral forces.
This unit is a true ISO 15552 profile cylinder, making it a direct dimensional replacement for any 32 mm bore, 450 mm stroke, PT ported standard cylinder using standard FA flange or LB foot mounts. Note that the standard adjustable air cushion only decelerates the piston at end-of-stroke; it will not hold a load vertically. If pneumatic pressure is lost, the rod will drift, requiring an external check valve or the SAIL locking variant for safety.
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 SAI32AX450 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X450 is a dimensionally interchangeable ISO 15552 profile cylinder. It shares the exact same mounting interface, 450 mm stroke, and 32 mm bore dimensions as other standard cylinders in this size class.
