About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-75S
The AirTAC SAIJ32X475-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5MPa and features a 12mm carbon-steel-derived rod, here upgraded to a SUS420J2 stainless steel rod for superior corrosion resistance. The integrated magnet (-S) enables seamless position sensing with CMSE reed or DMSE electronic switches.
With a 475mm nominal stroke and a 75mm adjustment range, this model yields a usable travel window of 400-475mm. This lets you fine-tune the retract end-position at commissioning or during product changeovers without adding external stops. The rear adjuster acts purely as a travel stop to set deceleration; it does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-75S Is Used
Machine Changeover
Dial in the exact 400-475mm end-position during product size changeovers without swapping the cylinder or bolting on external stops.
Variable End-Stop
Fine-tune the retract travel distance on automated assembly lines to accommodate varying part dimensions on the fly.
Sorting Diverters
Adjust the retract stroke of a sorting arm to handle different package sizes while maintaining ISO 15552 mounting interchangeability.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-75S the Right Cylinder?
Choose this 32mm bore when you need 402N push force at 0.5MPa and require trimming the stroke back by up to 75mm. If your application demands higher force, stepping up to the 40mm bore yields 628N at 0.5MPa. Because the 475mm stroke is long relative to the 32mm bore, the 12mm rod is susceptible to side-loading; an external guide is recommended to prevent premature seal wear.
An adjustable stroke is preferred over a fixed SAI cylinder when you need a variable end-stop for machine setup. For load-holding without live air, use a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on this rear stopper. This unit uses PT tapered ports and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 Adjustable Cylinder SAIJ32 SAIJ32AX475-75S FAQ
The 75mm rear adjuster acts as an external stopper that shortens the effective travel. For this 475mm stroke model, it creates a usable travel window of 400-475mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
It provides 402N of push force and 345N of pull force at 0.5MPa. The operational speed range is 30-800mm/s, and it features a SUS420J2 stainless steel rod with a PT tapered G1/8 port.
