About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-75
The AirTAC SAIJ63X160-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 160 mm travel back by up to 75 mm, creating a precise 85-160 mm usable window. Delivering 1559 N of push thrust at 0.5 MPa, it handles robust actuation tasks while the extruded aluminum barrel integrates sensor grooves on both sides for flexible switch placement.
This SKU is configured with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and utilizes PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-75 Is Used
Machine Changeover
Dial in the 85-160 mm travel window during product size transitions without physically replacing the actuator or bolting on external stops.
Variable End-Stop Tuning
Use the rear adjuster to fine-tune the retract position precisely during initial commissioning or when optimizing a multi-stage assembly process.
Robust Actuation
Leverage the 1559 N push force at 0.5 MPa and SUS420J2 stainless steel rod for durable performance in demanding, repetitive industrial environments.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-75 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) is insufficient, but a full 80 mm bore (2513 N at 0.5 MPa) would be excessive overkill. The 75 mm adjustment range is ideal for product changeovers on a line, letting operators dial in the exact end-of-stroke position without swapping the cylinder or adding external stops. If your process requires the load to be held mechanically without continuous air pressure, use an SAIL lock or BSAI clamp-lock cylinder instead of relying on this adjuster. For this 160 mm stroke, standard mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ63AX160-75 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 318 kgf (3180 N) of push thrust.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the nominal 160 mm, providing an adjustable travel window of 85 to 160 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
