About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-20S
The AirTAC SAIJ80X110-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a built-in rear stroke adjuster. It utilizes a robust 25mm carbon steel rod and generates 2513N of push force at 0.5 MPa, scaling up to 4523N at 0.9 MPa. Equipped with a magnet, it integrates seamlessly with CMSE reed and DMSE electronic sensors housed in the dual-side extruded aluminum barrel grooves.
This specific SKU provides a nominal 110mm stroke that can be dialed back by up to 20mm, creating a precise 90-110mm usable travel window for commissioning. The rear stopper screw allows you to fine-tune the retract end position without swapping out the entire cylinder or fabricating external stops. The adjuster acts purely as a travel stop and works in tandem with the variable air cushions at both ends to decelerate the load; it does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-20S Is Used
Variable End-Stop Tuning
Dial in the exact 90-110mm retract position during machine commissioning to accommodate varying material thicknesses without adding external physical stops.
Product Changeover
Quickly adjust the effective stroke by up to 20mm on automated lines when switching between different product sizes, reducing setup downtime significantly.
Deceleration Calibration
Pair the 20mm rear stopper with the built-in variable air cushions to precisely tune the end-of-stroke deceleration for heavy 80mm bore tooling.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-20S the Right Cylinder?
Choose this 80mm bore variant when a 50mm bore (982N push at 0.5 MPa) lacks the thrust for your tooling, but a 100mm bore (3927N at 0.5 MPa) is physically oversized. The 20mm adjustment range is ideal for machine setups requiring variable end-stops during product changeovers. Because the standard 110mm stroke is relatively short, side-load stress is minimal, though long unsupported strokes would still require an external guide. For true load-holding without continuous air pressure, this cylinder is insufficient; consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. To match this ISO 15552 interchangeable cylinder, specify: 80mm bore, 110mm stroke, 20mm adjustment, PT G3/8 port thread, Basic/LB/TC mounting, and a magnet for sensors.

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 SAIJ80X110-20S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.9 MPa, the push force increases to 4523N.
The rear adjuster screw allows you to mechanically shorten the 110mm nominal stroke by up to 20mm, providing a 90-110mm travel window. It functions as a physical stop to fine-tune the end position, but it does not lock or hold the load without live air pressure.
