About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-75
The AirTAC SAIJ32X375-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 300-375mm usable travel window. Delivering 402N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod for superior corrosion resistance and uses a PT tapered G1/8 port.
Because the nominal 375mm stroke is relatively long for a 32mm bore, the 12mm rod diameter requires external guidance to prevent excessive side-loading. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic sensors for position feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-75 Is Used
Machine Changeover
Dial in the exact end-stop for different product sizes on a packaging line without physically replacing the cylinder or adding external stopper blocks.
Assembly Calibration
Fine-tune the 300-375mm travel window during initial commissioning to perfectly time the pressing or indexing motion.
Variable Diverting
Adjust the retract stroke length on the fly to accommodate different package dimensions moving down a conveyor system.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-75 the Right Cylinder?
Choose this 32mm bore model when an application requires precise end-position tuning during commissioning or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. If your setup needs higher force, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa.
This SAIJ variant utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider 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 SAIJ32AX375-75 FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 375mm down to 300mm. This stopper only sets the end position and deceleration; it does not lock or hold the load without continuous air pressure.
