About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-40
The AirTAC SAIJ32X475-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 40 mm. This creates a usable stroke window of 435-475 mm, letting you fine-tune the end position at commissioning without adding external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This specific configuration uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and while this unit lacks a magnet, the grooves are ready to host reed CMSE or electronic DMSE switches if you later require position feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-40 Is Used
Product Changeovers
Dial in the 435-475 mm travel window during format changes to accommodate different product sizes without swapping hardware.
Commissioning Tuning
Use the rear stopper screw to precisely set the retract end position, eliminating the need for external mechanical stops.
Assembly Positioning
Leverage the 402 N push force to move light components, fine-tuning the final approach distance on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-40 the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient, or step up to the 40 mm bore if your application requires 628 N of push force. An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product changeovers or precise machine setup.
Because the stroke is 475 mm, the M10x1.25 rod will experience leverage forces under side loading; an external guide is recommended to prevent binding. To replace an ISO 15552 cylinder, match the 32 mm bore, 475 mm nominal stroke, 40 mm adjustment, PT port threads, and your required mounting interface (Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ32BX475-40 FAQ
The rear adjuster acts as a travel stop, allowing you to shorten the 475 mm nominal stroke by up to 40 mm, resulting in a usable travel window of 435-475 mm. It is not a lock; the cylinder still requires live air to hold position.
It provides 402 N of push force and 345 N of pull force at 0.5 MPa. The operational speed range is 30-800 mm/s, and it features adjustable air cushions at both ends.
