About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-75S
The AirTAC SAIJ32X75-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 0 to 75 mm window. Delivering 402 N of push force at 0.5 MPa, it uses a PT tapered port and a SUS304 stainless steel rod for superior corrosion resistance. The integrated magnet (-S) supports electronic DMSE and reed CMSE sensor switches housed in the dual-side extruded barrel grooves.
Because the adjustment range matches the nominal stroke, you can dial the extension down to a near-zero end position without adding external stops. The rear screw acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-75S Is Used
Variable End-Stop Tuning
Dial in the extension from 0 to 75 mm during machine commissioning to set precise end positions without physically remounting the actuator.
Product Size Changeovers
Quickly adapt conveyor stops and positioning arms to different package lengths on the fly, using the rear adjuster to modify the usable stroke.
Corrosive Setup Actuation
Leverage the SUS304 stainless steel rod for light-duty positioning tasks in washdown or corrosive manufacturing environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-75S the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of push force at 0.5 MPa, or step up to the 40 mm bore if you need 628 N. The massive 75 mm adjustment window is ideal for machine setups requiring variable end-stops during product changeovers. Unlike a fixed-stroke SAI cylinder, this adjustable version lets you set the exact extension at commissioning without swapping the hardware. To match this ISO 15552 replacement, specify the 32 mm bore, 75 mm stroke, 75 mm adjustment, PT port, Basic/LB/TC/FA/FTC/TCM1/TCM2 mounting, and the -S magnet.

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 SAIJ32BX75-75S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm. Since the nominal stroke is 75 mm, the usable travel window is 0 to 75 mm. The adjuster acts as a mechanical stop and does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. It features a SUS304 stainless steel rod (code B) for excellent corrosion resistance.
