About the Airtac SAI32 Standard Cylinder SAI32BX135S
The AirTAC SAI32X135-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 402 N at 0.5 MPa (563 N at 0.7 MPa), this 32mm bore unit is built to handle light-duty positioning. The 135mm stroke strikes a practical balance for intermediate reach tasks without consuming excessive envelope space.
This configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or washdown environments. Equipped with a built-in magnet (-S), the extruded aluminum barrel utilizes dual sensor grooves to accept CMSE or DMSE switches for precise end-of-stroke detection.

Where the Airtac SAI32 Standard Cylinder SAI32BX135S Is Used
Light-Duty Clamping
Provides reliable 402 N clamping force at 0.5 MPa for securing small machined components during secondary milling or drilling operations.
Package Diverting
Actuates a short-stroke diverter arm to route small totes or cardboard boxes along secondary conveyor lines in material handling systems.
Component Ejection
Pushes finished molded parts out of tight tooling cavities, utilizing the 135mm stroke to clear the press bed safely.
Is the Airtac SAI32 Standard Cylinder SAI32BX135S the Right Cylinder?
When sizing this actuator, consider stepping up to a 40mm bore if your application requires the 628 N push force at 0.5 MPa that the larger variant provides. Conversely, if your load is minimal, the 32mm bore remains optimal for preserving valuable machine space. The 135mm stroke is well below the 300mm threshold, so severe rod-bearing bending is not a primary concern, though side loads should still be minimized.
To guarantee a seamless direct replacement, match the ISO 15552 mounting dimensions, the PT G1/8 port, and your chosen accessory (such as an LB foot or FA flange). Because this is a standard double-acting cylinder, it relies on continuous air pressure to hold position; if pneumatic supply is lost, the rod will drift. For dead-load holding, integrate an external pilot-operated check valve or specify an SAIL locking variant.
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 SAI32BX135S FAQ
At 0.5 MPa, the cylinder provides a 402 N push force and a 345 N pull force. When supplied with 0.7 MPa, the push force increases to 563 N.
Yes. The SAI32X135-S is dimensionally interchangeable per ISO 15552. You can drop it into existing setups by matching the 32mm bore, 135mm stroke, and G1/8 port interface.
