About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX25-10S
The AirTAC SAIJ32X25-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 15 to 25 mm for precise end-position tuning. Built with an SUS420J2 stainless steel rod (code A), it delivers 402 N of push force at 0.5 MPa. The PT tapered port threads and integrated magnet for CMSE or DMSE sensors make it highly adaptable for compact automation.
This adjustable-stroke model allows you to fine-tune the retract position at commissioning without adding external stops. The rear adjuster acts purely as a travel stop and relies on the variable air cushion for deceleration; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX25-10S Is Used
Precision Component Seating
Dial in the exact 15-25 mm travel needed to seat delicate electronic components without damaging the product.
Machine Changeover
Quickly adjust the rear stopper by up to 10 mm during product size changeovers to minimize machine downtime.
Sensor Calibration Rigs
Leverage the -S magnet with DMSE sensors to verify position while tweaking the end-stop for calibration fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX25-10S the Right Cylinder?
Choose the SAIJ32X25-10-S when your application requires exact end-position tuning within a tight 15 to 25 mm travel window. If your setup needs slightly more thrust, stepping up to a 40 mm bore increases push force to 628 N at 0.5 MPa. This cylinder includes a magnet (-S) for electronic DMSE or reed CMSE position sensing.
As a dimensionally interchangeable ISO 15552 profile cylinder, it uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The 12 mm rod and M10x1.25 thread handle moderate side loads well, but always guide the load externally to prevent binding. Because the stroke is under 300 mm, side-load concerns are minimal, though proper alignment remains essential.
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 SAIJ32AX25-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the nominal 25 mm stroke by up to 10 mm, creating a 15 to 25 mm usable travel window. It only sets the end position and does not lock the load without continuous air pressure.
