About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX175-10
The AirTAC SAIJ63X175-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a highly specific 165-175 mm usable stroke window, giving you exact end-position control during machine commissioning without needing to swap out the entire unit. Built with a SUS420J2 stainless steel rod, it provides excellent resistance to moisture and minor environmental corrosion compared to standard carbon steel.
Delivering a robust 2182 N of push force at 0.7 MPa, this 63 mm bore actuator is designed for variable air cushioning at both ends to smooth out deceleration. It features PT tapered port threads and a standard M16x1.5 rod thread. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE solid-state switches if position feedback is required later.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX175-10 Is Used
Machine Changeover
Dial in the 165-175 mm travel window during product size transitions without swapping actuators or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract distance by up to 10 mm during commissioning to perfect seating pressure against a workpiece or tooling.
Assembly Line Actuation
Provides 2182 N of push force at 0.7 MPa for driving heavy clamps or lifts, with PT tapered ports for leak-free pneumatic connections.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX175-10 the Right Cylinder?
Choose this 63 mm bore when your application requires more thrust than a 50 mm cylinder (which provides 1374 N push at 0.7 MPa), but you want to avoid the larger footprint and higher air consumption of an 80 mm model. The 10 mm adjustable stroke is ideal for product changeovers on a line, letting you dial in the exact 165-175 mm travel window on the fly rather than machining external stops.
Remember that the rear adjuster acts purely as a mechanical travel stop to set the end position; it does not hold the load if air pressure drops. For fail-safe load holding without live air, you would need to step up to an SAIL pneumatic lock or BSAI clamp-lock cylinder. As a dimensionally interchangeable ISO 15552 profile cylinder, it uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Because the 175 mm stroke is relatively short, side-loading stress on the M16x1.5 rod is minimal, but external guides are still recommended for heavy lateral 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 SAIJ63AX175-10 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 175 mm stroke by up to 10 mm, providing a usable travel window of 165-175 mm. It sets the end position but does not lock the load without live air pressure.
At a 0.7 MPa operating pressure, this 63 mm bore cylinder provides 2182 N of push force and 1402 N of pull force. It can deliver a maximum push force of 2805 N at 0.9 MPa.
