About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-100
The AirTAC SAIJ32X475-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 375 to 475 mm window. Delivering 563 N of push force at 0.7 MPa, this 32 mm bore unit uses a SUS420J2 stainless steel rod to resist corrosion in demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Unlike a fixed-stroke SAI cylinder, this model integrates an external stopper screw at the rear cap, enabling precise end-position calibration during machine commissioning without adding external stops. The adjuster acts solely as a travel limit and does not hold the load without live air pressure. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-100 Is Used
Machine Setup Calibration
Dial in the exact end-position during initial commissioning using the 100 mm rear adjustment range, eliminating the need to swap cylinders for minor dimensional tweaks.
Product Changeover Lines
Quickly adapt the 375-475 mm travel window to accommodate varying package sizes on a packaging conveyor without installing external mechanical stops.
Variable End-Stop Assembly
Fine-tune the retraction point during light-duty assembly tasks to accommodate part tolerances, relying on the 402 N push force at 0.5 MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-100 the Right Cylinder?
Choose this adjustable-stroke model when your application requires variable end-stops or frequent product changeovers, allowing you to dial in the exact 375-475 mm travel distance on the fly. If your setup needs higher thrust, stepping up to the 40 mm bore provides 879 N of push force at 0.7 MPa, whereas dropping to a smaller bore reduces the footprint. Because the 475 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread provide a robust interface, but an external guide is recommended to prevent side-loading damage. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead. To match this ISO 15552 interchangeable cylinder, specify the 32 mm bore, 475 mm stroke, 100 mm adjustment, PT tapered port thread, and the desired mounting kit.

- ✓ 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 SAIJ32AX475-100 FAQ
The nominal stroke is 475 mm, but the rear adjuster allows you to shorten the effective travel by up to 100 mm, creating a usable travel window of 375 to 475 mm.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
