About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-20
The AirTAC SAIJ32X65-20 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, providing a usable travel window of 45 to 65 mm. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa. This bore features a 12 mm carbon steel rod, M10x1.25 rod thread, and PT G1/8 porting.
The rear adjustment screw acts as a travel stop to fine-tune end positions at commissioning without adding external stops. This version uses SUS420J2 stainless steel for the rod and omits the magnet, meaning CMSE or DMSE sensors cannot be used here. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-20 Is Used
Stroke Fine-Tuning
Dial in the exact end-of-stroke position within the 45 to 65 mm window during machine commissioning to perfect product placement.
Product Changeover
Quickly adjust the travel distance by up to 20 mm to accommodate slight variations in product size on the same production line.
Light Assembly
Utilize the 402 N push force for precise, low-force pressing and clamping tasks where exact end-positioning matters.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-20 the Right Cylinder?
Choose this 32 mm bore when your application requires roughly 402 N of push force at 0.5 MPa. If you need less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. The 20 mm adjustment range is ideal for product changeovers on a line, allowing you to dial back the 65 mm stroke by up to 20 mm without swapping the cylinder for a fixed-stroke SAI. Remember that the rear adjuster is a stop, not a lock; it will not hold the load without live air. For load-holding without pressure, consider a SAIL or BSAI cylinder, or use an external rod lock.
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 SAIJ32AX65-20 FAQ
At an operating pressure of 0.5 MPa, the SAIJ32X65-20 cylinder provides a push force of 402 N and a pull force of 345 N. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 65 mm nominal stroke by up to 20 mm, providing an effective travel window of 45 to 65 mm. It is a travel stop, not a lock, and does not hold the load without live air pressure.
