About the Airtac SAI32 Standard Cylinder SAI32X550S
The AirTAC SAI32X550-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 550mm non-standard stroke. It provides a push force of 402N at 0.5 MPa and 563N at 0.7 MPa, making it a precise fit for compact automation tasks requiring extended reach. This unit includes a magnet for proximity switching.
This model uses a carbon steel piston rod for structural rigidity over its long travel distance. The extruded aluminum barrel incorporates sensor grooves on both sides, directly supporting CMSE and DMSE reed switches for exact position detection across the 550mm travel path.

Where the Airtac SAI32 Standard Cylinder SAI32X550S Is Used
Extended Transfer
Pushes products between distant processing stations on a 550mm stroke without needing a secondary carriage.
Component Sorting
Actuates diverter gates in compact assembly machinery where a 32mm bore provides adequate 402N push force at 0.5 MPa.
Packaging Rejects
Extends to push defective items off a packaging line, using CMSE sensors to confirm the full 550mm extension.
Is the Airtac SAI32 Standard Cylinder SAI32X550S the Right Cylinder?
Because this 550mm stroke exceeds the standard 1000mm limit for the 32mm bore, it is manufactured as a made-to-order item. If your application requires greater thrust, stepping up to the 40mm bore yields 628N at 0.5 MPa, but verify your spatial envelope first. For strokes of 300mm or more, side load creates bending moments on the rod bearing; pair this cylinder with an external guide rail or select a guided cylinder to prevent premature seal wear.
This unit mounts via the ISO 15552 interface using accessories like LB foot brackets or FA flanges. It features a PT tapered port thread and includes the -S magnet option for sensors. Note that the adjustable air cushions decelerate the piston at end-of-stroke but do not lock the load; if you need true position holding without air pressure, consider the SAIL locking variant.
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 SAI32X550S 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, the SAI32X550-S is dimensionally interchangeable per ISO 15552 standards, allowing it to drop into existing mounting footprints like FA flanges or LB foot brackets.
