About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-75
The AirTAC SAIJ80X950-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 875 to 950 mm, letting you dial back the nominal stroke by up to 75 mm during commissioning. Delivering a robust 3518 N push force at 0.7 MPa, it handles heavy dynamic loads while maintaining a standard ISO 15552 mounting interface.
This SKU is configured with an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and carries PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper mechanism allows fine end-position tuning without adding external stops or swapping the cylinder.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-75 Is Used
Machine Changeovers
Dial in the 875-950 mm travel window during product size transitions without physically swapping out the actuator.
Variable End Stops
Fine-tune the retract position on long conveyor sorting gates to accommodate varying package lengths quickly.
Assembly Station Tuning
Adjust the stroke end-point precisely during commissioning to perfect the pressing depth of heavy components.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-75 the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N push at 0.5 MPa) lacks thrust or 100 mm (5497 N at 0.7 MPa) is oversized for your frame. The 75 mm adjustment range is ideal for product-size changeovers on a line, providing variable end stops without replacing the actuator. Because the 950 mm stroke is long and unsupported, an external guide is required to prevent rod sag and side-load damage.
The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, select a SAIL or BSAI series cylinder. This profile cylinder is dimensionally interchangeable per ISO 15552. To match this replacement, specify bore 80, stroke 950, 75 mm adjustment, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

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 SAIJ80AX950-75 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm from the 950 mm nominal length, creating an 875 to 950 mm usable travel window for fine-tuning the retract end position.
At 0.7 MPa operating pressure, this 80 mm bore cylinder provides a push force of 3518 N and a pull force of 2268 N. It can deliver up to 513 kgf at 1.0 MPa.
