About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-30S
The AirTAC SAIJ32X145-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 115-145 mm usable travel window, allowing you to trim the 145 mm nominal stroke by up to 30 mm during commissioning without swapping hardware. In the compact 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed or DMSE electronic solid-state switches fitted into the dual sensor grooves on the extruded aluminum barrel.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-30S Is Used
Machine Changeover
Dial in the 115-145 mm stroke window during product size changes to set new retract endpoints without adding external stopper blocks.
End-Position Tuning
Fine-tune the final retract position at commissioning to resolve minor mechanical misalignments in tooling and fixturing.
Sensor-Driven Sorting
Leverage the integrated magnet with DMSE electronic sensors to verify the adjusted position in automated sorting gates.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-30S the Right Cylinder?
Select this 32 mm bore adjustable cylinder when you need precise end-position tuning for product changeovers, stepping up from smaller units if you need over 400 N of push force at 0.5 MPa, or dropping down from a 40 mm bore (628 N push force) when space is constrained. The rear screw acts purely as a travel stop to set the 115-145 mm window; it does not lock the load. For load-holding without live air pressure, consider an external rod lock or the AirTAC SAIL series.
To match this ISO 15552 interchangeable cylinder, confirm the 145 mm stroke, 30 mm adjustment range, PT G1/8 port, and your preferred mounting from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for this 145 mm stroke, ensure adequate guiding if the load is heavy or off-center.
Quick checklist
- ✓ 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 SAIJ32BX145-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the 145 mm nominal stroke by up to 30 mm, creating a 115-145 mm travel window. It functions as a mechanical stop to fine-tune the retract position and is not a locking device.
