About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX210-10
The AirTAC SAIJ63X210-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 200 to 210 mm. It delivers a robust 2182 N of push force at 0.7 MPa, making it well-suited for mid-range industrial motion tasks. The barrel is extruded aluminum with sensor grooves on both sides, and this specific configuration features an SUS420J2 stainless steel rod and PT tapered port threads.
Unlike a fixed-stroke SAI cylinder, this model integrates an external rear stopper screw that allows technicians to dial back the nominal stroke by up to 10 mm during commissioning. This mechanism enables fine end-position tuning without swapping the cylinder or adding external stops. The adjuster functions strictly as a travel stop to set the end position, not as a lock, so it will not hold a load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX210-10 Is Used
Commissioning End-Stop Tuning
Dial in the exact 200 to 210 mm travel limit during machine setup without physically swapping cylinders or adding external mechanical stops.
Product Size Changeover
Quickly adjust the retract end-position by up to 10 mm to accommodate minor product size variations on a packaging line.
Mid-Range Positioning
Leverage the 2182 N push force at 0.7 MPa to move and position moderate workloads reliably within the tuned travel window.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX210-10 the Right Cylinder?
Select this 63 mm bore cylinder when your application requires precise 200 to 210 mm travel tuning and approximately 2182 N of force at 0.7 MPa. If your setup needs less push force, stepping down to a 50 mm bore yields 1374 N at the same pressure. Conversely, an 80 mm bore provides 3518 N for heavier payloads. This SKU uses PT tapered ports and lacks a magnet, so position sensing is not available without a different configuration. For holding loads without live air, consider a SAIL or BSAI series cylinder instead.
Because the 210 mm stroke is under the 300 mm side-load threshold, standard mounting is generally acceptable, though long unsupported loads should still use an external guide. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 standards.

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 SAIJ63AX210-10 FAQ
The rear adjuster screw acts as an external stopper, allowing you to shorten the effective stroke by up to 10 mm. This creates a 200 to 210 mm usable travel window for fine-tuning the end position at commissioning. The adjuster is a travel stop, not a lock, meaning it cannot hold a load without continuous air pressure.
At an operating pressure of 0.7 MPa, the SAIJ63X210-10 provides 2182 N of push force and 1402 N of pull force. It operates at speeds between 30 and 800 mm/s.
