About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-40
The AirTAC SAIJ32X450-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 410-450 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is equipped with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
The 40 mm adjustment range allows you to fine-tune the retract end position during commissioning or product changeovers without swapping the cylinder or adding external stops. It uses variable air cushions at both ends to decelerate the load, but the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-40 Is Used
Product Changeover
Dial in the 410-450 mm end position during format changes on packaging lines without replacing hardware.
Variable End Stops
Fine-tune the retract stroke to accommodate varying package sizes on a sorting conveyor.
Machine Commissioning
Adjust the 40 mm travel window during setup to perfectly time the sequence of operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-40 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force (345 N pull) at 0.5 MPa, stepping up to the 40 mm bore yields 628 N if your payload increases. The adjustable stroke is ideal for variable end-stops and machine setup, whereas a fixed SAI cylinder is sufficient for static positioning. If load-holding without continuous air pressure is required, consider the SAIL or BSAI series instead.
Because the 450 mm stroke is relatively long for a 12 mm rod, it is highly recommended to use an external guide to prevent excessive side-loading and premature seal wear. For a true ISO 15552 replacement match, verify the 450 mm stroke, 40 mm adjustment, PT port, and mounting choice from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ32BX450-40 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach 724 N push at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 450 mm down to 410 mm. It decelerates the travel end but does not lock the load without live air.
