About the Airtac SAI32 Standard Cylinder SAI32AX400S
The AirTAC SAI32X400-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. It provides a push force of 402 N and a pull force of 345 N at 0.5 MPa, making it suitable for medium-duty handling tasks. The 400 mm stroke offers extended travel for packaging and sorting equipment.
This variant includes a magnet for CMSE and DMSE sensor switches, which seat directly into the dual grooves on the extruded aluminum barrel. The piston rod is constructed from SUS420J2 stainless steel (material code A) for enhanced corrosion resistance, and it uses PT tapered port threads for a secure pneumatic connection.

Where the Airtac SAI32 Standard Cylinder SAI32AX400S Is Used
Package Sorting
Pushes light parcels across sorting belts over a 400 mm travel distance using 402 N of thrust at 0.5 MPa.
Component Transfer
Moves small machined parts between workstations, utilizing the SUS420J2 stainless rod for durability in mild industrial environments.
Drawer Actuation
Extends and retracts storage drawers or tool trays with reliable double-acting air pressure and integrated position sensing.
Is the Airtac SAI32 Standard Cylinder SAI32AX400S the Right Cylinder?
Choose this 32 mm bore when an application requires a compact footprint but a long 400 mm reach. If your setup needs less extension, stepping down to a shorter stroke reduces overall cycle time and rod mass. For tasks demanding higher thrust, the 40 mm bore provides 628 N at 0.5 MPa.
Because this model features a 400 mm stroke, the unsupported rod length is susceptible to bending under side loads. Implement an external guide rail or use a guided cylinder to prevent rod-bearing damage. If the machinery must hold a load vertically without continuous air pressure, add an external pilot check valve or select the SAIL locking variant, as standard air cushions only decelerate the piston at end-of-stroke and do not brake or hold loads.
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 SAI32AX400S 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. It can reach a maximum push force of 724 N at 0.9 MPa.
Yes, the SAI32X400-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounting interfaces using standard accessories like LB foot brackets or FA flanges, matching the exact 32 mm bore and 400 mm stroke.
