About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX800-30
The AirTAC SAIJ80X800-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 800 mm travel that can be fine-tuned down by up to 30 mm, yielding a precise 770-800 mm usable window during commissioning.
This variant is equipped with a SUS420J2 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads for a reliable pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily add CMSE reed or DMSE electronic switches if position feedback is later required.

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 SAIJ80AX800-30 Is Used
Variable End-Stop Positioning
Ideal for dialing in the exact retract distance within the 770-800 mm window during machine setup, allowing operators to fine-tune part ejection without replacing the entire actuator.
Product Size Changeover
Perfect for automated lines handling varying product lengths, where the 30 mm adjustment quickly adapts the stroke end-position to accommodate different package dimensions on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX800-30 the Right Cylinder?
The integrated 30 mm rear adjuster allows you to dial in the exact retract end-position without swapping components or adding external stops, which is far more efficient than using a fixed-stroke SAI cylinder during machine changeovers. Note that the rear screw acts only as a travel stop; it does not hold the load without live air, so for fail-safe load holding you should consider a SAIL or BSAI cylinder.
Because this model features an 800 mm stroke, the 25 mm rod and M20x1.5 rod thread will experience significant leverage under side loading. An external guide rail is strongly recommended to prevent premature seal wear. This SKU is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It operates at speeds between 30-800 mm/s.
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 SAIJ80AX800-30 FAQ
At the maximum 0.9 MPa operating pressure, the push force increases to 4523 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm, creating a 770-800 mm travel window. It only sets the end-position and does not lock the load without continuous air pressure.
