About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X475-30
The AirTAC SAIJ32X475-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel between 445 and 475 mm. Delivering 402 N of push force at 0.5 MPa, it utilizes a 12 mm carbon steel rod and G1/8 PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during product changeovers. The rear stopper simply dials in the end position, while the standard variable air cushion handles deceleration. Note that the adjuster acts as a travel stop, not a lock, so it cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X475-30 Is Used
Product Changeovers
Dial in the 445-475 mm travel window on packaging lines to accommodate different carton lengths without swapping hardware.
End-Stop Calibration
Fine-tune the rear stopper during machine commissioning to achieve exact positioning without adding external mechanical stops.
Variable Diverting
Adjust the stroke on the fly for sorting mechanisms that need to route items of varying widths down a production line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X475-30 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning in a compact footprint, stepping up from a 25 mm bore if your application requires more than the 402 N push force available here at 0.5 MPa. The adjustable 445-475 mm window is ideal for machines processing varying product sizes, replacing a fixed-stroke SAI cylinder when exact end stops fluctuate. For drop-in compatibility, match the PT port thread, the Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set, and omit the magnet if position sensing is not required.
Because this model features a 475 mm stroke, the 12 mm carbon steel rod will experience leverage forces at full extension. Always pair it with an external guide to prevent excessive side-loading, which can damage the seals and bearing. If your process requires the load to be held mechanically without continuous air pressure, consider an external rod lock or the AirTAC SAIL lock variant 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 SAIJ32X475-30 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 up to 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 475 mm stroke by up to 30 mm, providing a usable travel window of 445 to 475 mm. It sets the end position but does not lock the load without live air.
