About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-75S
The AirTAC SAIJ32X300-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to fine-tune the effective travel down from 300 mm to a 225 mm minimum. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod and a PT tapered port.
This configuration includes a piston magnet for positioning feedback via CMSE reed or DMSE electronic sensors. Because the 300 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to prevent excessive side-load wear on the M10x1.25 rod thread.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 225-300 mm window during machine commissioning to perfect pick-and-place locations without adding external stopper blocks.
Product Size Changeover
Quickly adapt a packaging line to different carton lengths by turning the rear adjustment screw, reducing downtime between production runs.
Sensor-Calibrated Movement
Leverage the built-in magnet with DMSE electronic sensors to confirm stroke endpoints across the adjusted travel range in automated assembly equipment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-75S the Right Cylinder?
Select this 32 mm bore unit when an application requires exact end-position tuning during commissioning without swapping cylinders, providing a 225-300 mm adjustable travel window. If your setup needs higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa.
The rear adjuster on this SAIJ acts purely as a travel stop and cannot hold a load without live air pressure; for true fail-safe load holding, consider an AirTAC SAIL or BSAI series cylinder. To match this ISO 15552 dimensionally interchangeable cylinder, specify: 32 mm bore, 300 mm stroke, 75 mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet option.

- ✓ 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 SAIJ32AX300-75S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 300 mm stroke by up to 75 mm. This creates a usable travel window of 225-300 mm for fine-tuning end positions at commissioning.
