About the Airtac SAI32 Standard Cylinder SAI32AX55
The AirTAC SAI32X55 is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit with a 55 mm stroke fits perfectly into space-constrained machinery. Its extruded aluminum barrel omits traditional tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches requires adding the -S option at order. The adjustable air cushions at both ends ensure smooth deceleration even at the maximum 800 mm/s operating speed.

Where the Airtac SAI32 Standard Cylinder SAI32AX55 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably knock small molded parts out of a fixture in tight assembly cells.
Package Diverting
Actuates a short-stroke diverter arm to route lightweight boxes on a conveyor line without occupying excessive frame width.
Clamp Actuation
Drives a secondary holding clamp for thin materials, utilizing the 55 mm stroke to clear the workspace when retracted.
Is the Airtac SAI32 Standard Cylinder SAI32AX55 the Right Cylinder?
Select this 55 mm stroke variant when a compact extension is needed without the bulk of larger bores. If your application requires slightly less force, stepping down is not an option below 32 mm in the SAI series, but if you need substantially more power, the 40 mm bore offers 628 N at 0.5 MPa. For this 55 mm stroke, side-load stress on the rod bearing is minimal, making it ideal for direct inline pushing without external guides.
Being dimensionally interchangeable per ISO 15552, this cylinder serves as a direct replacement for other ISO 15552 profile cylinders with matching 32 mm bore, 55 mm stroke, PT G1/8 ports, and standard mounting accessories like LB foot or FA flange. Note that if air pressure is lost, the piston will drift; maintaining a load mid-stroke requires live pressure or an external pilot-operated check valve.
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 SAI32AX55 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X55 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 and original ISO 6431 cylinders of the same bore and stroke. You can reuse existing mounting accessories like FA flanges or TC trunnions.
