About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-10S
The AirTAC SAIJ63X260-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal travel of 260 mm that can be dialed back by up to 10 mm, yielding a 250-260 mm usable window for exact end-position tuning at commissioning. Operating at 0.7 MPa, it delivers a push force of 2182 N and a pull force of 1402 N.
This variant features a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S model, it contains a magnet ready for CMSE reed or DMSE electronic solid-state switches. The rear stopper mechanism simply acts as a travel stop to set deceleration endpoints; it is not a lock and cannot hold a load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-10S Is Used
Machine Setup Calibration
Dial in the exact 250-260 mm end position during commissioning to perfect product changeovers without external stopper hardware.
Variable End-Stop Assembly
Adjust the retract distance precisely on the fly for modular assembly lines handling varying component sizes.
Positioning Clamp
Utilize the 2182 N push force at 0.7 MPa to secure parts, fine-tuning the travel limit to match fixture dimensions.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-10S the Right Cylinder?
Choose this 63 mm bore when your application requires the 2182 N push force at 0.7 MPa. If you need less force, stepping down to a 50 mm bore yields 1374 N push force, while stepping up to an 80 mm bore provides 3518 N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers without swapping the entire cylinder or adding external stops.
For any load-holding requirements without continuous air pressure, this cylinder is not suitable as the adjuster is only a stop. You would need to look at the SAIL air-released lock or BSAI clamp-lock series instead. When replacing an ISO 15552 cylinder, match the 63 mm bore, 260 mm stroke, 10 mm adjustment, PT tapered port threads, and the -S magnet option. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories. Because the 260 mm stroke is moderately long, ensure external guides are used if the application subjects the M16x1.5 rod thread to high side loads.

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 SAIJ63AX260-10S FAQ
At an operating pressure of 0.7 MPa, this 63 mm bore cylinder generates a push force of 2182 N and a pull force of 1402 N. At the maximum pressure of 1.0 MPa, the push force reaches 2805 N.
The rear adjuster screw allows you to shorten the 260 mm nominal stroke by up to 10 mm, providing a 250-260 mm travel window. This stopper sets the deceleration endpoint but does not lock or hold the load without live air pressure.
