About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-40S
The AirTAC SAIJ32X175-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 135-175 mm usable travel window by trimming up to 40 mm off the 175 mm nominal stroke, allowing precise end-position tuning during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant is equipped with a SUS420J2 stainless steel rod for improved corrosion resistance and includes a standard magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. Pneumatic cushioning at both ends manages deceleration, but the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-40S Is Used
Machine Changeover
Dial in the end-stop from 175 mm down to 135 mm instantly when switching product sizes on a packaging line, avoiding physical cylinder swaps.
Commissioning Calibration
Fine-tune the retract end position during initial setup to perfect a pressing or clamping distance without adding external mechanical stops.
Variable End-Stop Tooling
Accommodate slight variations in workpiece thickness on an assembly fixture by trimming the effective stroke up to 40 mm.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-40S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires 402 N push force at 0.5 MPa and variable end-stop positioning within a 135-175 mm window. The integrated rear adjuster allows fine-tuning during machine changeovers, whereas a fixed-stroke SAI cylinder requires exact stroke calculations upfront. If your process demands higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa.
Because this unit features a 175 mm stroke, the 12 mm rod diameter and M10x1.25 rod thread provide adequate support, though any long unsupported travel still necessitates an external guide to manage side loads. For dimensionally interchangeable ISO 15552 replacements, match the 32 mm bore, 175 mm stroke, 40 mm adjustment, PT tapered ports, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For applications requiring the load to be held without live air, 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 SAIJ32AX175-40S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the effective travel from the 175 mm nominal stroke down to 135 mm. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
