About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-30
The AirTAC SAIJ80X195-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position during commissioning. It provides a usable travel window of 165-195 mm, letting you dial back the nominal 195 mm stroke by up to 30 mm without adding external stops. In this configuration, the piston rod uses SUS420J2 stainless steel (code A) for improved corrosion resistance, and the PT tapered port threads ensure a robust, sealed connection at the G3/8 air supply.
Delivering a pull force of 2268 N at 0.5 MPa (or 4523 N at 0.9 MPa), this 80 mm bore actuator handles demanding loads while operating at speeds of 30-800 mm/s. The extruded aluminum barrel incorporates sensor grooves on both sides, and while this specific SKU lacks a magnet, the grooves are ready to host CMSE reed or DMSE electronic sensors when position feedback is required. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-30 Is Used
Machine Changeover
Dial in the 165-195 mm travel window during product size transitions to set new end positions rapidly without changing the actuator.
End-Position Tuning
Use the 30 mm rear stopper screw to fine-tune the retract stroke during commissioning, hitting exact mechanical targets without external shims.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-30 the Right Cylinder?
Choose this adjustable SAIJ model over a fixed-stroke SAI when your machine setup requires variable end-stops or precise product changeover tuning without physically swapping the cylinder. If your application needs less force, stepping down to a 63 mm bore yields 1402 N of pull force at 0.5 MPa; stepping up to a 100 mm bore provides 3681 N. Because the stroke is 195 mm, an external guide rail is recommended to prevent side-load wear on the rod over longer unsupported travels.
This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552. Remember that neither the rear adjuster nor the variable air cushions function as a lock; for true load-holding without live air, consider an external rod lock, the SAIL series, or the BSAI clamp-lock cylinder.
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 SAIJ80AX195-30 FAQ
The rear adjuster screw lets you shorten the 195 mm nominal stroke by up to 30 mm, creating a 165-195 mm usable travel window. It acts as a mechanical stop to set the retract end position precisely during setup.
At 0.9 MPa, the push force increases to 4523 N.
