The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX850-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 850mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ32X850-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The PT tapered port thread and SUS420J2 stainless steel rod (code A) ensure robust corrosion resistance for demanding environments.
This adjustable-stroke model lets you fine-tune the retract end position at commissioning without adding external stops. The rear adjuster acts purely as a travel stop, not a lock, so live air is required to hold the load. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.

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.

Dial in the exact 840 to 850mm retract position during machine commissioning without swapping physical hardware.
Quickly adjust the end-stop by up to 10mm to accommodate slight length variations when changing product runs on a line.
Stepping up to the 40mm bore increases push force to 628N, while dropping to a smaller bore reduces the footprint. Because the 850mm stroke is long and the 12mm rod is relatively slim, an external guide is recommended to prevent excessive side-load deflection.
An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product changeovers. For load-holding without continuous air pressure, this cylinder is insufficient; consider the SAIL air-released lock or BSAI clamp-lock instead. This SKU uses PT ports, omits the FB/CA/CB/CR mounting set, and lacks a magnet for sensors.
Quick checklist
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke by up to 10mm, creating a usable travel window of 840 to 850mm. It is a travel stop, not a lock, so it cannot hold the load without live air pressure.
