About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-100
The AirTAC SAIJ32X475-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 375 to 475 mm. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers 402 N of push force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Because the stroke extends to 475 mm on a 12 mm rod, an external guide is recommended to prevent excessive side-loading. The rear adjuster acts strictly as a travel stop for commissioning end-position tuning, not a lock, and holds no load without live air pressure. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-100 Is Used
Machine Changeover
Dial the travel back from 475 mm to 375 mm during product size changes without bolting on external stoppers or swapping the cylinder.
End-Position Tuning
Use the rear screw to precisely set the retract end-stop during commissioning, absorbing mechanical tolerance variations on the line.
Variable End Stops
Adjust the stroke on the fly for sorting or positioning different package sizes on a conveyor system.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-100 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa but needs a highly variable end-position. The 100 mm adjustment range is ideal for product changeovers, letting you dial back the 475 mm nominal stroke to 375 mm without swapping cylinders. If you need more thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa.
For load-holding without continuous air pressure, this plain SAIJ is insufficient since the rear adjuster only provides a deceleration stop. You would need an external rod lock or a related SAIL air-released lock cylinder. As an ISO 15552 interchangeable unit, match your replacement by confirming the 475 mm stroke, 100 mm adjust, PT ports, and SUS304 rod material.
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 SAIJ32BX475-100 FAQ
This 32 mm bore cylinder provides 402 N of push force and 345 N of pull force at 0.5 MPa, reaching up to 724 N push at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 475 mm nominal stroke down to a minimum of 375 mm. It functions as a travel stop, not a load lock.
