Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 350mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-30
The AirTAC SAIJ32X350-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 350 mm nominal stroke that can be fine-tuned backward by up to 30 mm, yielding a usable travel window of 320-350 mm. Driven by a 12 mm rod and G1/8 port, it delivers 402 N of push force at 0.5 MPa. The barrel is extruded aluminum with sensor grooves on both sides.
This configuration features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The rear adjustment screw acts purely as a mechanical stop to dial in end positions during commissioning; it does not lock the load without live air. For load-holding requirements without pneumatic pressure, an external pilot-operated check valve or a related SAIL lock cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-30 Is Used
Product Size Changeovers
Dial in the 320-350 mm retract position during format changes on a packaging line without physically replacing the cylinder or adding shims.
Machine Setup Commissioning
Fine-tune the end-of-stroke stop during initial machine commissioning to achieve exact positioning without recalculating fixed mechanical stops.
Variable End-Stop Diverter
Adjust the stroke dynamically on a conveyor diverter to accommodate different package lengths on the fly using the 30 mm trim range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628 N at the same pressure. The adjustable stroke is ideal for product changeovers on a line, allowing you to shift the retract end-stop by up to 30 mm without swapping the cylinder or adding external stops. Unlike a fixed-stroke SAI, this model gives you a 320-350 mm window for exact positioning.
Because this cylinder features a 350 mm stroke, the 12 mm rod and M10x1.25 rod thread may be subjected to side loads if the payload is unsupported; an external guide rail is recommended to prevent binding. Replacement or interchangeability is seamless via the ISO 15552 mounting interface, using PT tapered ports and the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series.

- ✓ 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 SAIJ32AX350-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the 350 mm nominal stroke by up to 30 mm, providing an effective travel window of 320-350 mm. The adjuster functions only as a travel stop and does not hold the load pneumatically.
