About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-10
The AirTAC SAIJ32X225-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the external stopper screw, you can fine-tune the effective travel within a 215 to 225 mm window, allowing precise end-position calibration at commissioning without adding external stops. It delivers 402 N of push thrust at 0.5 MPa, making it suited for lighter-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Remember that the rear adjuster functions strictly as a travel stop, not a load-holding lock; the cylinder requires live air to maintain its position.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-10 Is Used
Machine Changeover
Dial in the exact end-stop between 215 and 225 mm during product size changeovers without swapping out the entire cylinder.
End-Position Tuning
Fine-tune the retract position during initial commissioning to align tooling perfectly, eliminating the need for external stopper blocks.
Light Assembly
Utilize the 402 N push force at 0.5 MPa for precise pressing or feeding tasks that require a compact 32 mm profile body.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-10 the Right Cylinder?
Choose this 32 mm bore when your application requires a 225 mm stroke but demands exact end-position tuning within a 215 to 225 mm adjustable window. If your process needs less force, stepping down is not an option below 32 mm in this series, but if you need to overcome higher friction or move heavier payloads, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. An adjustable stroke is ideal for machine setups that face frequent product changeovers, whereas a fixed-stroke SAI cylinder is simpler for dedicated, single-product lines.
To replace this cylinder with an ISO 15552 interchangeable unit, match the 32 mm bore, 225 mm stroke, 10 mm adjustment range, PT G1/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 225 mm, the 12 mm diameter rod and M10x1.25 thread handle moderate side loads, but for any unsupported overhung loads, an external guide is recommended to prevent premature seal wear. For applications requiring the load to be held mechanically without live air pressure, consider the SAIL or BSAI series instead.

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 SAIJ32AX225-10 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push thrust and 345 N of pull thrust. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 225 mm stroke by up to 10 mm. This creates a usable travel window of 215 to 225 mm, allowing precise end-position tuning without replacing the cylinder.
