About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-75S
The AirTAC SAIJ32X145-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This creates a usable 70-145 mm adjustable window, letting you fine-tune the retract end position during commissioning without swapping the barrel or adding external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
Built with a SUS304 stainless steel rod and PT tapered ports, this unit integrates dual-side sensor grooves for CMSE reed and DMSE electronic solid-state switches. The 12 mm rod and M10x1.25 thread provide a compact interface, while the extruded aluminum barrel maintains dimensional interchangeability per ISO 15552.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-75S Is Used
End-Position Tuning
Dial in the exact retract distance within the 70-145 mm window during machine commissioning to perfect product handling without machining custom spacers.
Product Changeover
Quickly adapt the cylinder's effective stroke on the fly when running a new product size on the line, minimizing downtime between batches.
Sensor-Ready Positioning
Leverage the integrated -S magnet with DMSE electronic sensors to confirm the adjusted end positions in automated assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-75S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning over a wide 70-145 mm travel window. If your application requires higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The rear screw acts purely as a travel stop and deceleration point, not a lock; the SAIJ cannot hold a load without live air pressure. For load-holding requirements, select the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 145 mm stroke, 75 mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Since the stroke is under 300 mm, side-load risks are minimal, but long unsupported loads should still use an external guide.
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 SAIJ32BX145-75S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the 145 mm nominal stroke by up to 75 mm, providing a usable travel window of 70 to 145 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
