About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X900-10
The AirTAC SAIJ63X900-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 1559N of push force at 0.5 MPa. Its extruded aluminum barrel features sensor grooves on both sides, and it operates at speeds between 30 and 800 mm/s. With a standard carbon steel piston rod and PT tapered port threads, it provides robust actuation for demanding environments.
This model features a 900mm nominal stroke with a 10mm adjustment range, creating a precise 890-900mm usable travel window. The rear stopper screw allows you to fine-tune the retract end position at commissioning without adding external stops. The adjuster acts strictly as a travel stop and works alongside the standard variable air cushions to decelerate the load; it does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X900-10 Is Used
Product Changeover Tuning
Dial in the 890-900mm retract position precisely during line format changes, accommodating minor mechanical drift without swapping out the entire actuator.
Long-Stroke Assembly Press
Provides 1559N of push force at 0.5 MPa for seating components over a long travel distance, using the 10mm rear stopper to finalize the exact pressing depth.
Extended Reach Diverters
Actuates sorting arms across wider conveyor belts, using the rear adjuster to set the exact home position and prevent overshooting the mechanical stops.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X900-10 the Right Cylinder?
Choose this 63mm bore when you need more thrust than a 50mm cylinder (which provides 982N push at 0.5 MPa) but want to avoid the larger footprint of an 80mm unit. The adjustable stroke is ideal for machine setups requiring exact end-position tuning during product changeovers, rather than relying on a fixed-stroke SAI cylinder. To match this ISO 15552 replacement exactly, verify the 900mm stroke, 10mm adjustment, PT port threads, and your required mounting style from the available set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Because this cylinder has a 900mm stroke, the 20mm diameter carbon steel rod will experience leverage forces under side loads. For optimal longevity, ensure an external guide supports the load to prevent rod binding. If your application requires the load to be held in place without continuous live air, note that this adjuster is not a lock; you would need an external rod lock or a related SAIL pneumatic lock cylinder instead.

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 SAIJ63X900-10 FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At a maximum 1.0 MPa pressure, it can deliver up to 318 kgf.
The rear adjuster screw allows you to shorten the 900mm nominal stroke by up to 10mm, providing a usable travel window of 890-900mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
