About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-50S
The AirTAC SAIJ32X475-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 475mm nominal stroke that can be fine-tuned down by up to 50mm, creating a precise 425-475mm usable travel window. This built-in adjustability allows you to dial in the retract end-position at commissioning without swapping hardware.
Configured with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread, this model includes a magnet for position sensing. It accepts AirTAC CMSE reed and DMSE electronic solid-state switches in its dual-sided sensor grooves. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while omitting the FB, CA, CB, and CR mountings in favor of Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-50S Is Used
Changeover Calibration
Dial in the 425-475mm retract position precisely during machine changeovers without adding external mechanical stops.
Variable End Stops
Sort or divert items on a long conveyor line by fine-tuning the stroke endpoint in 50mm of rear adjustment.
Long-Reach Positioning
Push components into a fixture over a 475mm span, using the SUS304 rod for corrosion resistance in varied environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-50S the Right Cylinder?
Select this 32mm bore when an application requires exact end-position tuning over a long 475mm travel. The 50mm adjustment window is ideal for product changeovers, whereas a fixed SAI cylinder would require external stops. If your setup needs less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore yields 628N of push force at 0.5 MPa. Because the 475mm stroke is substantial for a 32mm bore, the 12mm rod and M10x1.25 thread will still need an external guide to prevent excessive side-loading on the piston.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 475mm stroke, 50mm adjustment, PT ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ32X475-50-S cannot hold a load without live air, so consider an AirTAC SAIL or BSAI cylinder if true load-holding is required.
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 SAIJ32BX475-50S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. If operated at 0.7 MPa, the push force increases to 563N.
The rear adjuster screw lets you shorten the effective stroke by up to 50mm from the 475mm nominal length, providing a usable travel window of 425-475mm. This stopper only sets the end position; it does not lock the load without continuous air pressure.
