About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-100S
The AirTAC SAIJ80X115-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. Equipped with a -S magnet for position sensing, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted into the dual-side sensor grooves. With a substantial 100 mm adjustment range, this 115 mm nominal stroke model yields a highly versatile usable travel window of 15 to 115 mm, allowing precise end-position tuning during commissioning.
Delivering 2513 N of push force and 2268 N of pull force at 0.5 MPa, this 80 mm bore actuator handles robust loads. The carbon steel rod features an M20x1.5 thread, providing a durable interface for mounting attachments. It utilizes PT tapered port threads (G3/8) and includes variable air cushions at both ends to decelerate the payload smoothly across its 30-800 mm/s speed range.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 15 to 115 mm during machine setup to accommodate varying material thicknesses without adding external stopper blocks.
Product Line Changeover
Quickly adapt the stroke end-position on packaging lines when switching between different carton sizes, leveraging the 100 mm adjustment range for rapid format changes.
Sensor-Driven Clamping
Use the integrated -S magnet with DMSE solid-state sensors to confirm clamp engagement before applying the 2513 N of thrust at 0.5 MPa.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-100S the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires high thrust (2513 N push at 0.5 MPa) but demands frequent product-size changeovers, as the 100 mm adjuster allows you to shift the end-stop anywhere within a 15-115 mm window without swapping hardware. If your force requirements are lower, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
The rear adjuster screw acts strictly as a mechanical travel stop to fine-tune the retract position, not as a lock. A plain SAIJ cylinder will not hold a load without live air pressure; for fail-safe load holding, select an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or install an external pilot-operated check valve. This unit is dimensionally interchangeable per ISO 15552.

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 SAIJ80X115-100S FAQ
The rear adjuster screw lets you mechanically shorten the effective stroke by up to 100 mm. This creates a usable travel window of 15 to 115 mm, allowing precise end-position tuning at commissioning or during product changeovers without replacing the cylinder.
At 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 513 kgf.
