About the Airtac SAI32 Standard Cylinder SAI32X425
The AirTAC SAI32X425 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and 425mm stroke. It provides a push force of 402N at 0.5 MPa and 563N at 0.7 MPa, making it well-suited for medium-duty linear motion tasks. The extruded aluminum barrel design omits tie rods for a clean exterior.
This model features a standard carbon steel piston rod and PT tapered port threads. Because no magnet is specified, it does not include the internal magnetic ring required for reed or solid-state sensor switches. For high-temperature environments up to 70 C, the standard TPU seals handle typical operations, though Viton (H) options exist for more extreme thermal demands.

Where the Airtac SAI32 Standard Cylinder SAI32X425 Is Used
Package Sorting
Drives diverters and pushers on conveyor lines with precise 425mm travel for medium-weight boxes.
Component Ejection
Ejects molded or machined parts from fixtures with reliable 563N force at 0.7 MPa.
Material Handling
Positions pallets and totes in automated storage systems requiring long linear displacement.
Is the Airtac SAI32 Standard Cylinder SAI32X425 the Right Cylinder?
If your application requires less force, stepping down is not an option below 32mm, but stepping up to the 40mm bore yields 628N at 0.5 MPa for heavier loads. Because this 425mm stroke exceeds the 300mm threshold, the unsupported rod length is susceptible to bending under side loads. We recommend using an external guide rail or a guided cylinder to prevent rod-bearing wear and premature failure.
As a genuine AirTAC component, this cylinder serves as a direct replacement for any ISO 15552 profile cylinder with a 32mm bore, 425mm stroke, G1/8 port, and standard mounting accessories like FA or LB. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If the load must be prevented from drifting when air pressure is lost, specify the SAIL variant with an air-released 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.
Airtac SAI32 Standard Cylinder SAI32X425 FAQ
At 0.5 MPa, the push force is 402N and the pull force is 345N. At 0.7 MPa, the push force increases to 563N.
Yes. It is built to the ISO 15552 standard, making its mounting dimensions interchangeable with other ISO 15552 profile cylinders of the same 32mm bore size.
