About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-75S
The AirTAC SAIJ32X150-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 75 to 150 mm. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-800 mm/s.
This pneumatic actuator utilizes a PT tapered port (G1/8) and includes a magnet for CMSE reed and DMSE electronic sensors. The rear adjustment screw acts purely as a mechanical stop to decelerate the piston, meaning it cannot hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-75S Is Used
Product Size Changeovers
Dial in the exact 75 to 150 mm end-stop during format changes on packaging lines without physically replacing the actuator.
Machine Setup Calibration
Fine-tune the final retract position at commissioning to precisely locate tooling, absorbing mechanical tolerances easily.
Variable End-Stop Positioning
Adjust the effective stroke dynamically for assemblies requiring multiple insertion depths within the 75 mm trim window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-75S the Right Cylinder?
Choose this 32 mm bore actuator when you need 402 N push force at 0.5 MPa with extensive on-machine end-position tuning, stepping up from smaller bores or down from a 40 mm bore that yields 628 N. The 75 mm adjustment range is perfect for product-size changeovers without swapping hardware. To replace an ISO 15552 cylinder, match the 150 mm nominal stroke, PT port, and desired mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Because the nominal stroke is 150 mm, side-load risks are moderate, but always ensure external guiding if pushing off-center. For applications requiring true load holding without live air, select an AirTAC SAIL or BSAI lock cylinder instead, as the SAIJ adjuster is strictly a travel stop.

- ✓ 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 SAIJ32BX150-75S FAQ
The rear adjuster screw lets you mechanically trim the effective travel back by up to 75 mm, providing a usable stroke window of 75 to 150 mm. The screw acts as a deceleration stop and does not lock the load without live air.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
