About the Airtac SAI32 Standard Cylinder SAI32X85
The AirTAC SAI32X85 is a double-acting ISO 15552 profile cylinder featuring an 85mm stroke and a 32mm bore. It generates 402N of push force and 345N of pull force at 0.5 MPa, making it well-suited for compact, mid-stroke positioning tasks.
This model features a standard carbon steel piston rod and utilizes a PT tapered port thread. For environments requiring heat resistance, you can specify Viton (H) seals instead of the standard TPU, or opt for SUS304 stainless steel rod material for corrosion defense.

Where the Airtac SAI32 Standard Cylinder SAI32X85 Is Used
Small Part Ejection
Ideal for pushing small machined components out of a fixture using its 85mm stroke and 402N push force at 0.5 MPa.
Package Diverter
Actuates short-stroke diverter arms on packaging lines where a compact 32mm bore footprint is required.
Gripper Actuation
Provides reliable linear motion for opening and closing small pneumatic grippers in automated assembly.
Is the Airtac SAI32 Standard Cylinder SAI32X85 the Right Cylinder?
Choose this 32mm bore when your application requires around 402N of push force at 0.5 MPa. If your project demands less force, step down to a smaller bore; if you need substantially more power, a 40mm bore provides 628N. Because this is an 85mm stroke, side-load bending is minimal, but always verify rod-bearing alignment.
This cylinder functions as a direct replacement for any ISO 15552 profile cylinder matching its 32mm bore, 85mm stroke, G1/8 port, and mounting dimensions. Note that a standard SAI does not hold position unpowered; if your machine requires fail-safe load holding, select the SAIL pneumatic lock variant or add 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.
