About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-75S
The AirTAC SAIJ100X350-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 275 to 350 mm. Built with a 100 mm bore, it generates 5497 N of push force at 0.7 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves.
This adjustable-stroke model uses a standard carbon steel rod and a PT tapered G1/2 port. The rear stopper mechanism allows precise end-position tuning during commissioning without adding external stops. The adjuster acts solely as a travel stop for deceleration and does not hold the load without live air pressure; for true load-holding, consider SAIL or BSAI variants.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-75S Is Used
Machine Setup Changeover
Dial in the 275 to 350 mm travel window during product changeovers to fine-tune end positions without physically swapping cylinders or adding external stops.
Variable End-Stop Positioning
Use the rear adjuster to set precise retract distances for multi-tier tooling plates, ensuring accurate mechanical stops before the air cushion takes over.
Heavy Material Handling
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or actuators, using the 25 mm rod to handle high dynamic loads with external guidance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-75S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust, such as 3927 N at 0.5 MPa, combined with variable end-stop positioning. If a smaller footprint is needed, the 80 mm bore offers 2513 N push at 0.5 MPa, while the 125 mm bore provides 6136 N for heavier loads. The 75 mm adjustment range is ideal for product-size changeovers on a line without swapping the cylinder.
Because the 350 mm stroke is significant, the 25 mm rod diameter should be supported by an external guide to prevent side-load damage. This SAIJ model shares the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552, featuring a PT port and the -S magnet option.

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 SAIJ100X350-75S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 350 mm down to 275 mm. This provides a 75 mm tuning window for commissioning without changing the cylinder mount.
At 0.7 MPa operating pressure, the SAIJ100X350-75-S generates 5497 N of push force and 3681 N of pull force. It can reach a maximum push force of 7068 N at 0.9 MPa.
