About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X85-75S
The AirTAC SAIJ100X85-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa and features a 25mm carbon steel rod with an M20x1.5 thread. A built-in magnet enables position sensing with AirTAC CMSE reed and DMSE solid-state switches.
With a nominal 85mm stroke and a 75mm adjustment range, you can fine-tune the usable travel window anywhere from 10mm to 85mm. This built-in rear stopper lets you dial in exact end positions at commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set omits FB, CA, CB, and CR brackets, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X85-75S Is Used
Variable End-Stop Tuning
Dial in the exact 10-85mm travel window during machine setup to accommodate new product sizes without physically replacing the actuator.
Changeover Optimization
Rapidly adjust the retract end-position on the fly during format changeovers, minimizing downtime on automated production lines.
High-Force Positioning
Leverage the 3927N push force to move heavy pallets or fixtures, relying on the rear stopper to set precise final positioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X85-75S the Right Cylinder?
Choose this 100mm bore when you need higher thrust than a 63mm bore (1559N at 0.5 MPa) but want to avoid the bulk of a 125mm unit. An adjustable stroke is ideal for product changeovers on a packaging line, letting you alter the end-stop without swapping the cylinder. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an SAIL or BSAI cylinder. To match this ISO 15552 footprint, specify the 100mm bore, 85mm stroke, 75mm adjustment, PT ports, and the -S magnet option.
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 SAIJ100 Adjustable Cylinder SAIJ100X85-75S FAQ
The external rear screw acts as a mechanical stopper, allowing you to trim the effective travel back from the 85mm nominal stroke down to a 10mm minimum, creating a 10-85mm usable window.
At 0.5 MPa operating pressure, it provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
