About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-40
The AirTAC SAIJ63X160-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 120-160 mm usable travel window by allowing you to dial back the 160 mm nominal stroke by up to 40 mm. This bore size delivers 1559 N of pull force at 0.5 MPa and 2805 N of push force at 0.9 MPa, making it well-suited for medium-duty handling tasks.
The piston rod is constructed from SUS420J2 stainless steel, offering enhanced corrosion resistance compared to standard carbon steel. The barrel is an extruded aluminum profile with sensor grooves on both sides. Because this is an adjustable-stop cylinder rather than a locking device, the rear screw sets the end position but will not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-40 Is Used
Machine Setup Calibration
Dial in the exact 120 to 160 mm end-stop during initial commissioning to perfect pressing positions without machining custom spacers.
Product Size Changeover
Quickly adjust the retract distance up to 40 mm on packaging lines switching between different product widths.
Variable End-Stop Positioning
Use the rear adjuster screw to set precise retraction limits for multi-stage assembly processes requiring flexible travel.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-40 the Right Cylinder?
Select this 63 mm bore cylinder when your application requires 1559 N of pull force at 0.5 MPa and you need the flexibility to fine-tune the retract end-position during commissioning without swapping components. If your setup demands less force, the 50 mm bore provides 825 N of pull; if you need more clamping power, stepping up to the 80 mm bore yields 2268 N. The SAIJ63X160-40 uses a PT tapered G3/8 port and supports mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 160 mm stroke, 40 mm adjustment range, PT G3/8 port, and SUS420J2 rod material. For load-holding applications without continuous air pressure, consider the AirTAC SAIL or BSAI series instead of relying on the rear stopper. Since the 160 mm stroke is below the 300 mm threshold, side-load stress is minimal, but external guides are still recommended for rigid loads.

- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ63AX160-40 FAQ
The rear adjuster screw allows you to shorten the 160 mm nominal stroke by up to 40 mm, providing an adjustable travel window of 120 to 160 mm. It acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it provides 1559 N of pull force and 2182 N of push force. At the maximum 1.0 MPa pressure, the push force reaches 2805 N.
