About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX425-30
The AirTAC SAIJ32X425-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 395 to 425 mm, allowing you to dial back the nominal 425 mm stroke by up to 30 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This SKU is configured with an SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting AirTAC CMSE reed or DMSE electronic switches. Because the rear adjuster functions strictly as a mechanical stop to set the travel end, it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX425-30 Is Used
Machine Changeover
Fine-tune the 395-425 mm travel window during product size changes to set precise end positions without replacing the entire cylinder assembly.
Variable End Stops
Dial in the exact retraction point for sorting gates or pushers, using the 30 mm rear adjuster to compensate for mechanical wear over time.
Assembly Positioning
Achieve precise lower-end positioning for pressing or locating pins, relying on the 402 N push force and the rear mechanical stop.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX425-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa, or step up to the 40 mm bore if you need a higher 628 N output. The adjustable stroke is ideal for product changeovers on a line, letting you fine-tune the end position without swapping the cylinder or bolting on external stops. For true load-holding without continuous air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock series instead.
With a 425 mm stroke on a 32 mm rod, this configuration requires an external guide to prevent excessive side-loading and rod deflection. It uses a G1/8 port and maintains the standard ISO 15552 mounting interface, supporting Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories.
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 SAIJ32AX425-30 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The 30 mm rear adjuster allows you to trim the 425 mm nominal stroke, creating a usable travel window of 395 to 425 mm.
No, the rear adjuster is a travel stop, not a locking device. It sets the end-of-stroke position but does not hold the load without live air. For true load-holding, use a SAIL or BSAI series cylinder.
