About the Airtac SAI32 Standard Cylinder SAI32AX85
The AirTAC SAI32X85 is a double-acting ISO 15552 profile cylinder engineered for standardized mounting interchangeability without tie-rods. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit paired with an 85 mm stroke fits compact automation sequences perfectly.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads and operates without a magnet, relying on its extruded aluminum barrel for structural rigidity.

Where the Airtac SAI32 Standard Cylinder SAI32AX85 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push small molded parts out of a machining fixture.
Package Diverting
Actuates a lightweight routing gate on a packaging line with its precise 85 mm stroke.
Clamp Actuation
Secures thin materials in a woodworking station where a compact 32 mm bore footprint is necessary.
Is the Airtac SAI32 Standard Cylinder SAI32AX85 the Right Cylinder?
Select this 85 mm stroke model when a compact 32 mm bore cylinder is required for light-force tasks. If your application demands less than 402 N at 0.5 MPa, consider stepping down, though the 32 mm bore already represents the entry point for this ISO 15552 series. For higher force requirements, stepping up to the 40 mm bore yields 628 N at 0.5 MPa.
Because this is a double-acting cylinder, it relies entirely on continuous air pressure to move and maintain its position; it will drift if air is lost. To replace an existing ISO 15552 cylinder, match the 32 mm bore, 85 mm stroke, PT G1/8 port, and your required mounting accessory like an LB foot or FA flange. Note that since -S is not specified, this unit lacks internal magnets for reed sensors.
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 SAI32AX85 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X85 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 32 mm bore, 85 mm stroke, and G1/8 port.
