About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-10
The AirTAC SAIJ100X155-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 145-155 mm, letting you dial back the 155 mm nominal stroke by up to 10 mm during commissioning without adding external stops. It delivers a robust 5497 N push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. It supports a speed range of 30-800 mm/s and offers adjustable air cushions at both ends to decelerate moving loads smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-10 Is Used
Machine Changeover
Quickly adjust the retraction end-stop by up to 10 mm during product size changes without swapping the cylinder or adding external mechanical stops.
Heavy Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy jigs into exact position, using the rear screw for final micron-level tuning.
Assembly Line Indexing
Control the 145-155 mm travel window precisely on automated lines, relying on the adjustable air cushions to decelerate loads smoothly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-10 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires high thrust, such as 3927 N at 0.5 MPa, and precise end-position tuning. The 10 mm rear adjuster is ideal for product changeovers on a line, acting as a travel stop to set exact retraction distances. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N push force at 0.5 MPa. Conversely, a 125 mm bore provides 6136 N for heavier loads.
Keep in mind the rear adjuster only sets the travel end and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. This SAIJ100X155-10 is dimensionally interchangeable with ISO 15552 cylinders and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ100BX155-10 FAQ
It features a rear adjusting screw that acts as a stopper, allowing you to shorten the effective stroke within a 145-155 mm window. This provides up to 10 mm of fine-tuning at commissioning without changing the cylinder's physical mounting.
At 0.7 MPa operating pressure, the push force is 5497 N, and the pull force is 3681 N. It can deliver a maximum push force of 7068 N at 0.9 MPa.
