About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-30
The AirTAC SAIJ80X195-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push force at 0.5 MPa. By turning the external stopper screw, you can trim the nominal 195mm travel back by up to 30mm, creating a precise 165-195mm usable window. This allows operators to fine-tune end positions during commissioning without swapping out the entire unit.
Built with a carbon steel piston rod and a PT tapered port thread, this extruded aluminum barrel design integrates variable air cushions at both ends to manage kinetic energy. The rear screw acts purely as a travel stop to set deceleration limits and does not lock the load without live air. For position holding without pneumatic pressure, external rod locks or related types like SAIL and BSAI are required.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-30 Is Used
Product Changeovers
Dial in the 165-195mm travel window during format size changes on packaging lines, using the rear screw to set new end positions rapidly without changing hardware.
Variable End Stops
Provide adjustable diverting or stopping points along a conveyor by fine-tuning the stroke limit in 30mm increments during machine commissioning.
Assembly Pressing
Apply up to 2513N of push force at 0.5 MPa for pressing tasks, using the adjustable stopper to precisely control the insertion depth of different components.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-30 the Right Cylinder?
Selecting this 80mm bore makes sense when an application requires substantial thrust, such as 2513N push at 0.5 MPa, but demands on-the-fly end-position tuning. If your setup only requires 1559N of push force, stepping down to a 63mm bore saves space, whereas moving up to a 100mm bore yields 3927N for heavier loads. The adjustable stroke is ideal for product-size changeovers on a line, providing a variable end-stop instead of relying on a fixed-stroke SAI cylinder.
When matching this ISO 15552 cylinder for a direct replacement, verify the 80mm bore, 195mm stroke, 30mm adjustment range, PT port thread, and standard carbon steel rod. Because the 195mm stroke approaches the threshold where rod deflection becomes a concern, ensure adequate external guiding to prevent excessive side loading on the rod seals. This unit supports a mounting subset of 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 SAIJ80 Adjustable Cylinder SAIJ80X195-30 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 195mm nominal stroke by up to 30mm, providing an effective travel range of 165-195mm. It functions as a travel stop and does not hold the load without live air pressure.
