The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 90mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAIJ80X90-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 15 to 90 mm without adding external stops. Delivering a robust 4523N of push force at 0.9 MPa, it is built for demanding positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This variant is equipped with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a built-in magnet (-S) that operates seamlessly with CMSE reed and DMSE electronic solid-state sensors. The rear adjustment screw acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Rapidly dial in the stroke from 90mm down to 15mm when switching machinery to handle a different product size, eliminating the need to physically swap cylinders.
Precisely set the retract end-position during machine commissioning to prevent mechanical crashes, using the rear screw rather than relying on fixed stops.
Adapt the travel distance on automated assembly lines for varying component widths, leveraging the 2513N push force to move heavy fixtures.
Choose this 80mm bore cylinder when an application requires high thrust, such as the 2513N push force at 0.5 MPa, but demands flexible end-position tuning during commissioning or product changeovers. If your process requires less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa, whereas larger loads up to 7068N push at 0.9 MPa would necessitate moving up to a 100mm bore.
The SAIJ80X90-75-S is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It features PT tapered port threads (G3/8) and a 25mm rod with an M20x1.5 thread. For load-holding without live air pressure, consider the SAIL or BSAI series, as the adjuster here is strictly a travel stop.
Quick checklist
The rear adjuster screw acts as a mechanical stop that trims the effective stroke. For this model, you can reduce the nominal 90mm stroke by up to 75mm, providing a usable travel window of 15 to 90mm. It only sets the end position and does not lock the load without air pressure.
At an operating pressure of 0.5 MPa, the SAIJ80X90-75-S generates 2513N of push force and 2268N of pull force. At 0.9 MPa, the push force increases to 4523N.
