About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX140-10S
The AirTAC SAIJ100X140-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 140 mm travel that can be dialed back by up to 10 mm, giving you a precise 130-140 mm usable window for fine-tuning end positions at commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy positioning tasks with ease.
This SKU is built with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads (G1/2). The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic sensors, which seat cleanly into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts strictly as a travel stop to decelerate the load, not as a lock, so live air pressure is required to hold position.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX140-10S Is Used
Tooling Calibration
Dial in the exact 130-140 mm end-stop during machine commissioning to perfect press strokes without adding external shims.
Product Changeover
Quickly adjust the retract position by up to 10 mm on packaging lines when switching to a slightly shorter product format.
Heavy Positioning
Leverage 3927 N of push force at 0.5 MPa to move heavy jigs into place, using the rear screw to fine-tune the resting point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX140-10S the Right Cylinder?
Choose this 100 mm bore when 80 mm (2513 N at 0.5 MPa) lacks the thrust for your tooling or 125 mm (6136 N) is oversized. The 10 mm adjustable window is ideal for machine setups requiring variable end-stops without swapping hardware. For load-holding without air pressure, select the BSAI clamp-lock or SAIL locking cylinder instead, as the SAIJ adjuster is not a brake. Since this is a 140 mm stroke, side-load is minimal, but for strokes 300 mm or above, an external guide rail is recommended to protect the M20x1.5 rod thread. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR), ensuring dimensionally interchangeable ISO 15552 mounting.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100AX140-10S FAQ
It features a rear adjusting screw that lets you shorten the 140 mm nominal stroke by up to 10 mm, providing a 130-140 mm travel window. This allows you to fine-tune the retract end-position during setup without changing the cylinder.
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
