About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-100S
The AirTAC SAIJ80X175-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push force at 0.5 MPa. Its defining trait is a massive 100mm adjustment range, transforming the 175mm nominal stroke into a highly flexible 75-175mm usable travel window. This built-in adjustability allows you to dial in exact retract end-positions during commissioning without adding external stops.
This variant features a carbon steel piston rod and PT tapered ports. It includes a magnetic piston (-S) for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches housed in the dual-side sensor grooves. Remember that the rear screw acts purely as a travel stop to set deceleration, not as a load-holding lock; maintaining position requires continuous live air.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-100S Is Used
Product Changeovers
Quickly reconfigure the 75-175mm travel window for different packaging sizes on a single line without swapping out the entire actuator.
Machine Setup
Fine-tune the retract end-position during initial commissioning to achieve precise mechanical alignment without machining custom spacers.
Variable End Stops
Use the 100mm adjustment screw to test multiple retraction depths dynamically during prototype development and fixture testing.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-100S the Right Cylinder?
Choose this 80mm bore when an application requires substantial force (2513N push at 0.5 MPa) alongside extreme setup versatility. If you need less thrust, stepping down to a 63mm bore yields 1559N. Select this adjustable J-series over a fixed SAI cylinder when a machine handles frequent product changeovers, allowing operators to reconfigure the 75-175mm travel window on the fly. To replace an ISO 15552 cylinder, match the 80mm bore, 175mm stroke, PT port threads, and the -S magnet requirement.
Because the nominal stroke is 175mm, side-load risks are moderate, but you should still ensure adequate external guiding for heavy loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. If true load-holding without live air pressure is needed, look to the SAIL or BSAI locking cylinders instead of relying on the rear adjuster.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80X175-100S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 75-175mm, letting you set the exact retract position without changing the cylinder.
At 0.5 MPa operating pressure, it provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
