About the Airtac SAI32 Standard Cylinder SAI32AX550S
The AirTAC SAI32X550-S is a double-acting ISO 15552 profile cylinder engineered for extended reach applications. Delivering a push force of 563 N at 0.7 MPa, this 32 mm bore unit utilizes a 550 mm stroke to handle lengthy traversing motions. As a non-standard made-to-order stroke, it is tailored specifically for machinery requiring displacement well beyond typical intermediate distances.
Built with an extruded aluminum barrel and integrated sensor grooves on both sides, this model supports CMSE and DMSE switches via its integrated magnet. The piston rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and it features PT tapered port threads. It operates reliably at speeds between 30 and 800 mm/s.

Where the Airtac SAI32 Standard Cylinder SAI32AX550S Is Used
Extended Transfer Lines
Pushes products between distant processing stations on long conveyor systems where a 550 mm reach is necessary.
High-Bay Ejection
Ejects totes or cartons from deep storage lanes, utilizing the full 550 mm stroke to clear shelving obstructions.
Long-Stroke Part Feeding
Advances raw material blanks into machining centers, relying on the 563 N push force to overcome sliding friction.
Is the Airtac SAI32 Standard Cylinder SAI32AX550S the Right Cylinder?
Selecting this 550 mm stroke cylinder requires careful attention to rod-bearing loading. At extended lengths, unsupported rods are highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature wear. If your application requires less travel, stepping down to a 25 mm bore offers 402 N at 0.5 MPa, while a 40 mm bore provides 628 N at 0.5 MPa for heavier payloads.
This unit provides true ISO 15552 mounting interchangeability, allowing seamless integration with standardized foot (LB), flange (FA/FB), or trunnion (TC) accessories. Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If pressure is lost, the rod will drift, requiring an external pilot-operated check valve or the SAIL locking variant for secure positioning.
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 SAI32AX550S FAQ
At an operating pressure of 0.7 MPa, this 32 mm bore cylinder generates a push force of 563 N and a pull force of 345 N at 0.5 MPa.
Yes, the SAI32X550-S is dimensionally interchangeable per ISO 15552. You can match the bore, stroke, PT port, and mounting accessories directly, but always verify overall length dimensions from the datasheet.
