The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX200-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 200mm 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 SAIJ32X200-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 200 mm travel by up to 50 mm. This creates a precise 150-200 mm usable window, perfect for fine-tuning end positions during commissioning without swapping hardware.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts purely as a travel stop to set deceleration alongside the air cushions, so it will not hold a 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.

Quickly adapt the 150-200 mm travel window when switching product sizes on a packaging line, avoiding the need to physically swap out cylinders for different formats.
Fine-tune the retract position during initial commissioning to achieve exact mechanical alignment, using the rear screw rather than adding external stopper blocks.
Leverage the SUS304 stainless steel rod in light chemical or washdown environments while dialing in the exact stroke needed for repetitive test cycles.
The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed SAI cylinder locks you into a single exact dimension. For any load-holding requirements without continuous air pressure, you must look to the SAIL or BSAI series, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 200 mm nominal stroke, 50 mm adjustment range, PT tapered port threads, and the -S magnet option. Because the 200 mm stroke is relatively long for this compact bore, ensure you provide an external guide to handle side loads, as the 12 mm rod and M10x1.25 thread can only support so much lateral stress. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
Quick checklist
If you increase pressure to 0.7 MPa, the push force rises to 563 N.
The rear adjuster allows you to shorten the 200 mm nominal stroke by up to 50 mm, creating a usable travel window of 150-200 mm. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
