About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-75
The AirTAC SAIJ32X90-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 15-90 mm usable travel window from its 90 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. This bore size operates at speeds from 30-800 mm/s and includes variable air cushions at both ends.
The integrated rear stopper screw allows precise end-position tuning during commissioning without adding external stops. Remember that this adjuster acts only as a travel stop and does not hold the load without live air pressure. For load-holding requirements, consider an external pilot-operated check valve or the SAIL lock series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-75 Is Used
Product Changeovers
Dial in the 15-90 mm travel window on the fly to accommodate different package sizes on a packaging line without changing the cylinder.
Machine Setup
Fine-tune the retract end-position during commissioning to achieve exact sensor alignment and mechanical synchronization.
Variable End Stops
Use the rear stopper to test multiple extend lengths during prototyping before locking in a final mechanical position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-75 the Right Cylinder?
Choose this 32 mm bore when an application requires up to 402 N push force at 0.5 MPa but demands highly variable end positions; if you need greater thrust, stepping up to the 40 mm bore provides 628 N. The massive 75 mm adjustment range on a 90 mm stroke is ideal for machines processing multiple product sizes on a single line, replacing the need to swap fixed-stroke SAI cylinders. This model uses a SUS304 rod and PT ports, making it dimensionally interchangeable per ISO 15552.
Because the nominal stroke is under 300 mm, side-load stress is manageable, but always ensure the load is guided to prevent binding. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Note that without a magnet, this base unit cannot host CMSE or DMSE sensors.
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 SAIJ32BX90-75 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 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to trim the effective stroke back by up to 75 mm, creating a 15-90 mm usable travel window. It acts as a mechanical stop and does not lock the load without air pressure.
