About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-30
The AirTAC SAIJ32X475-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 445-475mm usable travel window. Equipped with a 12mm carbon steel rod and M10x1.25 threading, it delivers 402N of push thrust at 0.5MPa. This unit utilizes a SUS420J2 stainless steel rod (code A) for improved corrosion resistance.
The extruded aluminum barrel includes sensor grooves on both sides, though no magnet is fitted to this configuration. The rear adjustment screw functions strictly as a travel stop to decelerate the end position, meaning it will not hold a load without continuous live air pressure. For applications requiring pneumatic locking, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-30 Is Used
Machine Changeover
Dial in the exact retract distance within the 445-475mm window when switching machinery between different product sizes.
End-Position Tuning
Trim the stroke up to 30mm during setup to perfect the end-of-travel stopping point without swapping the cylinder.
Assembly Line Setup
Use the rear stopper to dial back the nominal travel for precise component placement on automated assembly lines.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-30 the Right Cylinder?
Choose this 32mm bore when your application requires less force than the 40mm bore (which provides 628N push at 0.5MPa) but still needs a long 475mm stroke. The adjustable stroke is selected over a fixed SAI cylinder when you need to fine-tune the retract end position during commissioning or product changeovers without adding external stops.
When replacing an ISO 15552 cylinder, match the 32mm bore, 475mm stroke, 30mm adjustment range, PT tapered port thread, and standard mounting interface. Because the stroke is 475mm, the 12mm rod requires an external guide to prevent excessive side-loading and premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.
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 SAIJ32AX475-30 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it delivers 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from 475mm down to 445mm. It sets the travel end but does not lock the load without live air pressure.
