About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-75S
The AirTAC SAIJ32X105-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a push force of 402 N at 0.5 MPa and features a carbon steel piston rod with an M10x1.25 thread. The integrated magnet supports position sensing via CMSE reed or DMSE solid-state switches.
With a 105 mm nominal stroke and a 75 mm adjustment code, this model provides a highly flexible usable travel window of 30 to 105 mm. You can dial back the retract position precisely at commissioning without swapping the cylinder or adding external stops. It features an extruded aluminum barrel with sensor grooves on both sides and uses a PT tapered port thread.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 30 to 105 mm during machine commissioning to accommodate different product sizes without external stops.
Product Changeover
Quickly adjust the stroke window on packaging lines when switching between part variants, saving setup time and reducing downtime.
Precise Feed Positioning
Fine-tune the end-of-stroke position on light-duty feeding mechanisms where a 402 N push force is sufficient.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-75S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa but require significant travel flexibility on the retract end. If your application needs less adjustment range, a fixed-stroke SAI cylinder is simpler, but this SAIJ model excels in machine setups requiring variable end-stops during product changeovers. For higher force demands, stepping up to the 40 mm bore yields 628 N at 0.5 MPa.
When ordering, confirm the 105 mm stroke, 75 mm adjustment, PT port, and the -S magnet. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for load-holding without pneumatic pressure, consider an external rod lock or the AirTAC SAIL series. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32X105-75S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the nominal 105 mm, giving an adjustable travel window of 30 to 105 mm. It functions as a mechanical stop and does not lock the load without air pressure.
