About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-10S
The AirTAC SAIJ32X550-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 540-550 mm usable travel window by allowing you to trim the 550 mm nominal stroke back by up to 10 mm. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod for improved corrosion resistance and features a built-in magnet for position sensing.
Unlike fixed-stroke SAI units, this model lets you fine-tune the retract end position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, supporting CMSE reed and DMSE electronic switches. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-10S Is Used
Product Changeover
Dial in the 10 mm adjustment window to quickly switch end-stroke positions when handling different product sizes on the same conveyor line.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to achieve precise 540-550 mm travel without swapping out the entire cylinder.
Sensor-Driven Automation
Leverage the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches for reliable end-of-stroke detection in automated assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa. If your setup needs less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is ideal for product changeovers on a line, letting you dial in the exact end-of-stroke position. For load-holding without continuous air pressure, you must look to the SAIL (air-released lock) or BSAI (clamp-lock) series, as the SAIJ adjuster is not a locking device.
Because the 550 mm stroke is relatively long for a 12 mm rod, an external guide is recommended to prevent excessive side-loading and rod deflection. This cylinder uses PT tapered ports (G1/8) and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. It is dimensionally interchangeable per ISO 15552 standards.

- ✓ 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 SAIJ32AX550-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The operational speed range is 30-800 mm/s, adjustable via flow controls on the G1/8 PT ports.
The rear adjuster screw allows you to shorten the 550 mm nominal stroke by up to 10 mm, creating a 540-550 mm usable travel window. This stopper sets the retract end position but does not lock or hold the load without live air pressure.
