About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-10S
The AirTAC SAIJ63X290-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 280 to 290 mm, allowing you to trim the retract end-position by up to 10 mm during commissioning. Delivering a pull force of 1402 N at 0.5 MPa, it fits medium-force applications perfectly. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.
This variant uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It accepts PT tapered port threads sized G3/8 and relies on variable air cushions at both ends to decelerate the piston. Remember that the rear adjuster and cushions act only as travel stops; they do not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-10S Is Used
Machine Changeover
Dial in the exact 280-290 mm retract position when switching product sizes on a packaging line, using the rear screw to set the new end stop without changing hardware.
End-Position Tuning
Trim up to 10 mm off the nominal stroke during commissioning to perfect the seating force against a workpiece, ensuring precise alignment without external shims.
Variable End Stops
Establish a customizable retract depth for assembly presses, allowing operators to adjust the cushioning and physical stop point for delicate components.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-10S the Right Cylinder?
Choose this 63 mm bore cylinder when you need 1402 N of pull force at 0.5 MPa, stepping up from a 50 mm bore that yields 825 N, or down from an 80 mm bore providing 2268 N. The 10 mm adjustable range is ideal for fine-tuning the end stop during machine setup or product changeover, avoiding the need to swap physical cylinders or bolt on external stopper blocks. As a direct ISO 15552 dimensionally interchangeable replacement, match your bore, 290 mm stroke, PT G3/8 port, and preferred mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 290 mm, use an external guide to support the load and prevent excessive side-loading on the M16x1.5 rod thread.

- ✓ 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 SAIJ63AX290-10S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 280-290 mm travel window. It acts as a physical stop to fine-tune the end position at commissioning, but it does not lock or hold the load without continuous air pressure.
At 0.5 MPa operating pressure, it provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
