About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-10
The AirTAC SAIJ32X450-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 440-450mm usable travel window. Delivering 402N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and PT tapered ports. This configuration provides precise end-position tuning without swapping out the entire actuator.
Because the adjuster acts purely as a mechanical stop and does not lock the load, live air is required to maintain position. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the easy addition of CMSE or DMSE switches if sensing is needed later.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-10 Is Used
Commissioning Calibration
Dial in the exact 440-450mm end-of-stroke position during initial machine setup to accommodate sensor targets or mechanical variances.
Product Changeover
Quickly trim the stroke up to 10mm on a packaging line when switching to a slightly different carton or product size.
Fixture Positioning
Fine-tune the retraction point of a clamping fixture without adding bulky external stopper blocks to the machine frame.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-10 the Right Cylinder?
Choose this 32mm bore when an application requires a 402N thrust at 0.5 MPa with exact end-position tuning; step up to a 40mm bore if you need 628N of push force. An adjustable stroke is preferred over a fixed SAI cylinder when you need to dial in a 440-450mm travel window during machine commissioning. For drop-in compatibility, match the 32mm bore, 450mm stroke, 10mm adjustment, PT ports, and standard mounting options.
With a 450mm stroke, the 12mm rod should be guided externally to prevent excessive side-loading and premature seal wear. If the machinery demands true load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI cylinder instead of relying on this rear stopper.
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 SAIJ32BX450-10 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 450mm nominal stroke by up to 10mm, creating a 440-450mm travel window. It functions as a mechanical stop for end-position tuning and is not a locking device.
