About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-75S
The AirTAC SAIJ32X450-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 450 mm stroke that can be fine-tuned backward by up to 75 mm, creating a precise 375-450 mm usable travel window. Equipped with a SUS304 stainless steel rod and a PT tapered port, it delivers 402 N of push force at 0.5 MPa.
Because the adjuster acts purely as a mechanical stop on the retract end, it cannot hold a load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-75S Is Used
Product Size Changeover
Quickly dial the retract end position back by up to 75 mm to accommodate varying package lengths on a packaging line without changing hardware.
Machine Setup Tuning
Fine-tune the 450 mm travel window during commissioning to perfectly time the contact point, preventing impact damage to delicate tooling.
Variable End Stops
Provide adjustable physical stops for diverter arms or pushers where the exact required stroke length may shift based on process variables.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-75S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa, or step up to the 40 mm bore for 628 N if your payload increases. The 75 mm adjustment range is ideal for product changeovers, allowing you to dial in the end position without swapping cylinders or adding external stops. For fixed travel without the rear screw, a standard SAI cylinder is sufficient.
At 450 mm of travel, the 12 mm rod requires external guiding to prevent excessive side-loading and binding. This SAIJ model uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If your application requires true load-holding without continuous air pressure, 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 SAIJ32BX450-75S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective travel from the 450 mm nominal stroke down to as little as 375 mm. It functions as a mechanical stop to set the end position, but it is not a lock and will not hold the load without live air pressure.
