About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-10S
The AirTAC SAIJ63X165-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position by up to 10 mm. This yields a usable travel window of 155-165 mm, letting you dial in the exact end-stop during commissioning without swapping out the unit. Built with a SUS420J2 stainless steel rod and a PT tapered port, it delivers 1559 N of push force at 0.5 MPa.
Because it includes a magnet (-S), this model directly supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side sensor grooves. The rear adjuster acts purely as a mechanical stop to set deceleration and end-position; it 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-10S Is Used
Machine Changeover
Dial in the 155-165 mm travel window during product size changes on a packaging line, using the rear screw to set new end positions instantly without changing the cylinder.
End-Stop Tuning
Achieve exact retract positions during machine commissioning by adjusting the stopper, eliminating the need to fabricate and bolt on external spacers.
Assembly Positioning
Drive a 1559 N press or assembly head at 0.5 MPa, relying on the built-in magnet and DMSE electronic sensors to confirm the adjusted end-position.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-10S the Right Cylinder?
Select this 63 mm bore when an application requires precise variable end-stops and moderate thrust, stepping up from a 50 mm bore that yields 982 N at 0.5 MPa. The adjustable stroke is chosen over a fixed-stroke SAI when you need on-the-fly product changeover or commissioning fine-tuning. To match this ISO 15552 replacement exactly, specify the 63 mm bore, 165 mm stroke, 10 mm adjustment, PT G3/8 port, and the -S magnet.
With a 165 mm stroke, the 20 mm diameter rod and M16x1.5 thread handle standard loads well, but any long unsupported travel still requires an external guide to prevent side-loading damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

- ✓ 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-10S FAQ
The rear adjuster allows you to shorten the nominal 165 mm stroke by up to 10 mm, creating a 155-165 mm usable travel window. It functions as a mechanical stop to tune the end position and does not lock or hold the load without live air.
At 0.5 MPa operating pressure, the SAIJ63X165-10-S provides a push force of 1559 N and a pull force of 1402 N. The maximum push force reaches 2805 N at 0.9 MPa.
