About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-30S
The AirTAC SAIJ32X350-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a 402N push force at 0.5 MPa. By turning the rear stopper screw, you can fine-tune the effective travel window from 320 to 350 mm without adding external stops. This makes it highly effective for commissioning setups where precise end-of-stroke positioning is critical.
This variant features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a built-in magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the PT tapered porting ensures a tight, reliable pneumatic connection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-30S Is Used
End-Position Tuning
Dial in the exact retract distance within the 320-350 mm window during machine commissioning without swapping out the entire cylinder.
Product Changeovers
Quickly adapt the stroke length on automated lines handling varying product sizes by adjusting the rear stopper screw.
Precision Assembly
Use the fine-tuned end-stop to guarantee consistent pressing or placement depth across multiple cycles.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-30S the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your machine requires exact end-position tuning during product changeovers rather than a fixed-stroke SAI model. If your application demands greater thrust, stepping up to the 40mm bore yields a 628N push force at 0.5 MPa. Because the stroke is 350mm, the 12mm rod requires an external guide rail to prevent side-loading damage.
The rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. To match this ISO 15552 dimensionally interchangeable cylinder, specify: 32mm bore, 350mm stroke, 30mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet option.

- ✓ 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 SAIJ32AX350-30S FAQ
It provides a push force of 402N and a pull force of 345N at 0.5 MPa. The operating speed ranges from 30 to 800 mm/s.
The rear adjuster screw lets you trim the nominal 350mm stroke back by up to 30mm, creating a usable travel window of 320 to 350mm to fine-tune the end position.
