About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-75
The AirTAC SAIJ32X300-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 225-300 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it uses a 12 mm carbon steel rod with an M10x1.25 thread and PT tapered port. This bore size operates efficiently at speeds between 30-800 mm/s.
Unlike a fixed-stroke SAI, this model lets you dial in the retract end-position during commissioning without adding external stops. The rear adjuster acts purely as a travel stop and works alongside the 27 mm air cushion to decelerate the load; it does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of AirTAC CMSE reed or DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-75 Is Used
Machine Commissioning
Fine-tune the 225-300 mm travel window during setup to hit exact retract positions without swapping cylinders.
Product Changeover
Quickly shorten the stroke by up to 75 mm when line product sizes change, minimizing downtime.
Variable End-Stop
Use the rear stopper to set precise ejection points on a conveyor without adding external mechanical stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-75 the Right Cylinder?
Choose this 32 mm bore when you need precise retract tuning on a 300 mm stroke but only moderate thrust, such as 402 N push at 0.5 MPa. If your application requires greater force, stepping up to the 40 mm bore yields 628 N push at the same pressure. The 75 mm adjustment range is ideal for product changeovers, allowing you to shorten the travel from 300 mm down to 225 mm on the fly.
Because the stroke is 300 mm, the 12 mm rod requires an external guide to prevent excessive side-loading on the seals. For load-holding without continuous air pressure, this cylinder is not a lock; consider the SAIL or BSAI series instead. This SAIJ configuration features a SUS420J2 stainless steel rod, PT tapered ports, and omits the magnet. It uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ32AX300-75 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers 82 kgf.
The rear adjuster screw lets you trim the effective travel back by up to 75 mm from the 300 mm nominal stroke, creating a 225-300 mm travel window. It acts as a mechanical stop to set the end position and is not a locking device.
