About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-75S
The AirTAC SAIJ32X140-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel window to 65-140 mm. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa. Equipped with a SUS304 stainless steel rod, it handles minor side loads effectively while resisting corrosion.
This unit includes a magnetic piston for position sensing, supporting AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The rear stopper allows precise end-position tuning without adding external stops, and the standard air cushions decelerate the travel at both ends.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-75S Is Used
Product Changeover
Dial in the 65-140 mm travel window during line changeovers to accommodate varying package sizes without swapping hardware.
End-Stop Calibration
Fine-tune the retract position during commissioning to perfect a pressing or clamping operation using the rear screw.
Sensor Equipped Setup
Leverage the magnetic piston with DMSE electronic sensors for precise position feedback in automated assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-75S the Right Cylinder?
Choose this 32 mm bore when you need up to 402 N of force at 0.5 MPa; if your application requires greater thrust, stepping up to the 40 mm bore yields 628 N. The 75 mm adjustment window is ideal for machine setups requiring variable end-stops during product changeover. To replace an existing ISO 15552 cylinder, match the 140 mm stroke, 75 mm adjuster, PT G1/8 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting.
Because the nominal stroke is 140 mm, external guiding is not yet critical, but always ensure the load is supported. Note that the rear adjuster acts only as a travel stop, not a lock; for fail-safe load holding without live air, select the SAIL or BSAI series instead.
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 SAIJ32BX140-75S FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the 140 mm nominal stroke by up to 75 mm. This creates a usable travel window of 65-140 mm for fine-tuning end positions without changing the cylinder.
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.
