The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX300-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 300mm 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 SAIJ32X300-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster.
This variant uses an SUS420J2 stainless steel rod for improved corrosion resistance and accepts PT tapered port threads. Because the 300 mm stroke is relatively long for a 32 mm bore, the 12 mm rod should be guided externally to prevent excessive side-loading. The rear screw acts purely as a travel stop and does not lock 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.

Fine-tune the retract distance within a 280-300 mm window during machine setup to achieve perfect product alignment without external shims.
Quickly adjust the stroke by up to 20 mm when switching between part sizes on a packaging line, reducing downtime.
The adjustable window is perfect for dialing in a 280-300 mm travel distance on the fly.
For any 300 mm stroke, ensure external guides support the load to minimize side-load wear on the rod. If your process requires the cylinder to hold its position without continuous air pressure, select a SAIL lock or BSAI clamp-lock cylinder instead, as the SAIJ adjuster is a stop, not a brake. This model uses the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a 280-300 mm usable travel window. This stopper fine-tunes the end position but does not lock the load without live air pressure.
