About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-10S
The AirTAC SAIJ125X160-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 150-160 mm usable travel window, allowing you to trim the nominal 160 mm stroke by up to 10 mm during commissioning. In the 125 mm bore class, it delivers 6136 N push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This unit includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides. Operating speed is 30-500 mm/s, and the variable air cushions at both ends work with the rear stopper to decelerate the load smoothly.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-10S Is Used
Heavy-Duty Positioning
Provides 6136 N of thrust at 0.5 MPa for moving heavy fixtures, using the 10 mm stroke adjuster to dial in the exact final position during machine setup.
Product Changeover
Quickly adapt the end-of-stroke stop from 150 to 160 mm when switching product sizes on a line, eliminating the need to physically swap out the cylinder.
Assembly Line Dials
Handles robust clamping and pressing tasks with its 32 mm stainless steel rod, while the DMSE electronic sensors confirm exact end positions.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-10S the Right Cylinder?
Select this 125 mm bore cylinder when a 100 mm bore (offering 3927 N push at 0.5 MPa) is insufficient for your load, but a 160 mm bore (10053 N at 0.5 MPa) would be excessive overkill. The 10 mm adjustable range is ideal for fine-tuning the end position on product changeovers without swapping the cylinder or adding external stops. Ensure your control system uses PT tapered port threads for a leak-free connection.
For any stroke of 160 mm or more, consider side-load risks; the 32 mm rod diameter handles robust loads, but long unsupported strokes still require an external guide. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air. For fail-safe load holding, use an external rod lock or consider the AirTAC SAIL or BSAI series. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ125 Adjustable Cylinder SAIJ125AX160-10S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, providing a usable travel window of 150 to 160 mm. This stopper sets the travel end and works with the air cushion to decelerate the load, but it does not lock the position without live air pressure.
At 0.5 MPa operating pressure, it provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N.
