About the Airtac SAI32 Standard Cylinder SAI32X425S
The AirTAC SAI32X425-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion tasks. It provides a push force of 402 N and a pull force of 345 N at 0.5 MPa, making it well-suited for medium-duty handling across a 425 mm travel distance. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that easily drops into standardized ISO 15552 mounting interfaces.
This specific configuration includes a standard carbon steel piston rod for robust everyday industrial service. Equipped with a -S magnet, the barrel's dual-side sensor grooves readily accept CMSE or DMSE reed switches for exact end-of-stroke position detection. Air filtration to 40 um and adjustable pneumatic cushioning at both ends guarantee smooth, impact-free operation.

Where the Airtac SAI32 Standard Cylinder SAI32X425S Is Used
Package Sorting
Drives diverting arms on sorting conveyors, using the magnet and CMSE sensors to confirm pusher extension and retraction over the 425 mm travel.
Vertical Elevation
Lifts small material trays in automated assembly cells, relying on the 402 N push force to elevate light-to-medium payloads smoothly.
Component Transfer
Moves delicate electronic parts between processing stations, benefiting from the adjustable end-cushioning to prevent impact damage at cycle completion.
Is the Airtac SAI32 Standard Cylinder SAI32X425S the Right Cylinder?
Choosing this 32 mm bore over the larger 40 mm variant (which yields 628 N push force at 0.5 MPa) is ideal when footprint minimization and efficiency are prioritized over raw thrust. The 425 mm stroke is a standard length, but because it exceeds 300 mm, the extended rod is susceptible to bending under lateral loads. To prevent premature rod-bearing wear, pair this cylinder with an external linear guide or use a guided cylinder assembly to absorb any side forces.
For applications requiring the piston to remain locked during air loss or valve centering, note that the standard adjustable air cushions only decelerate the rod near stroke ends and do not hold loads. In such scenarios, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. Replacement planning requires matching the 32 mm bore, 425 mm stroke, G1/8 PT port, and appropriate mounting accessories like LB foot brackets or TC trunnions.
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 SAI32X425S FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder generates a push force of 402 N and a pull force of 345 N. If higher pressure is applied, the push force increases to 563 N at 0.7 MPa and 724 N at 0.9 MPa.
Yes, the SAI32X425-S is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing ISO 15552 mounting footprints and use standard accessories, matching the 32 mm bore, 425 mm stroke, and G1/8 port size.
