About the Airtac SAI32 Standard Cylinder SAI32X400
The AirTAC SAI32X400 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 400mm stroke. It delivers 402N of push force and 345N of pull force at 0.5 MPa, making it a solid choice for standard industrial actuation. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that aligns with ISO 15552 dimensional interchangeability standards.
This specific configuration utilizes a carbon steel piston rod and PT (tapered) thread ports. Since no magnet is specified, it operates without integrated magnetic sensing; should position detection become necessary, adding a magnet (-S) allows the use of CMSE or DMSE switches in the dual-side sensor grooves.

Where the Airtac SAI32 Standard Cylinder SAI32X400 Is Used
Package Sorting
Provides 402N of push force at 0.5 MPa to deflect parcels and totes on automated distribution lines.
Small Press Assembly
Drives light-duty press fits and sub-component seating over a 400mm travel range without tie-rod obstructions.
Drawer Ejection
Extracts filled trays or product cassettes from machinery, utilizing the full 400mm stroke length.
Is the Airtac SAI32 Standard Cylinder SAI32X400 the Right Cylinder?
When specifying this 32mm bore unit, verify that 402N at 0.5 MPa is sufficient for your load; if higher thrust is required, stepping up to the 40mm bore yields 628N. For a 400mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, guide the load externally or select a guided linear actuator. Keep in mind that this standard cylinder relies on adjustable air cushions to decelerate the piston at both ends and will not hold a load if air pressure is lost—consider the SAIL locking variant if mid-stroke positioning safety is required. Replacement direct units must match the 32mm bore, 400mm stroke, PT G1/8 port, and standard mounting accessories.
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 SAI32X400 FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
No, the adjustable air cushions only decelerate the piston at the end of the stroke and do not lock the load. If you need fail-safe holding, use the SAIL variant with an air-released lock or an external rod lock.
