About the Airtac SAI32 Standard Cylinder SAI32BX140
The AirTAC SAI32X140 is a double-acting ISO 15552 profile cylinder engineered for standardized mounting. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit is built around an extruded aluminum barrel without tie rods. The 140 mm stroke provides the extension needed for compact sorting and clamping tasks.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. Fluid connections use PT tapered threads, and because no magnet is specified, it operates without electronic position sensing. For higher temperature environments, the standard TPU seals can be swapped for Viton (H) or NBR (N).

Where the Airtac SAI32 Standard Cylinder SAI32BX140 Is Used
Package Diverting
Provides the precise 140 mm extension needed to push small cartons off a sorting belt with 402 N of force.
Small Part Clamping
Ideal for holding light aluminum or plastic components during machining, utilizing its SUS304 rod for clean environments.
Gate Actuation
Reliable double-acting motion for opening and closing lightweight access gates on automated machinery.
Is the Airtac SAI32 Standard Cylinder SAI32BX140 the Right Cylinder?
Choose this 32 mm bore when an application requires roughly 400 N of push force at 0.5 MPa. If your assembly needs less energy, stepping down is not an option below 32 mm in the SAI series, but stepping up to a 40 mm bore yields 628 N at 0.5 MPa for heavier payloads. At 140 mm of stroke, side-load stress on the rod bearing remains moderate, but ensure your payload is guided to maximize seal life.
This cylinder serves as a dimensionally interchangeable direct replacement per ISO 15552. To match this exact unit, specify a 32 mm bore, 140 mm stroke, PT port thread, and your desired mounting accessory like an LB foot or FA flange. Because it lacks a magnet, do not order CMSE or DMSE sensors. Note that standard air cushions only decelerate the piston at stroke ends; they will not hold a load if air pressure drops. Use the SAIL variant if dead-end locking is required.
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.
