About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-10S
The AirTAC SAIJ32X125-10-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 125mm nominal stroke that can be fine-tuned down by 10mm, providing a precise 115-125mm usable travel window for exact end-position calibration.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet for position sensing. It accepts PT tapered port threads (G1/8) and utilizes variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-10S Is Used
Machine Commissioning
Dial in the exact 115-125mm end-stop during initial setup to compensate for mechanical tolerances without adding external shims.
Product Changeover
Quickly adjust the stroke by up to 10mm on the line when switching between slightly different product sizes.
Sensor Mapping
Leverage the integrated magnet to confirm exact CMSE or DMSE switch trip points relative to the adjusted travel limit.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-10S the Right Cylinder?
Choose this 32mm bore when an application requires 402N push force at 0.5 MPa but demands on-the-fly end-position tuning without swapping cylinders. If your setup needs less force, stepping down is not an option in this series, but stepping up to a 40mm bore yields 628N. The 10mm adjustment range is perfect for dialing in slight mechanical differences during machine commissioning. Remember that the rear adjuster acts only as a travel stop, not a load-holding lock; for dead-air positioning, consider an external pilot-operated check valve or the SAIL series. To replace an ISO 15552 cylinder, match the 32mm bore, 125mm stroke, PT port, and -S magnet.
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 SAIJ32BX125-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach up to 724N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 125mm nominal stroke by up to 10mm, creating a 115-125mm travel window. It acts as a physical stop to set the end position and does not lock the load without live air pressure.
