The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X50-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 50mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ200X50-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations requiring precise end-position tuning. By integrating a rear stopper mechanism, this model allows you to dial back the nominal 50 mm stroke by up to 30 mm, creating a highly adaptable 20-50 mm usable travel window. This built-in adjustability eliminates the need to swap out the entire cylinder or bolt on external stops during machine commissioning or product changeovers.
The robust 40 mm carbon steel rod and M36x2 thread provide exceptional rigidity, while the extruded aluminum barrel features sensor grooves on both sides for straightforward CMSE or DMSE sensor integration. Equipped with PT tapered G3/4 ports and 50 mm variable air cushions at both ends, it ensures smooth deceleration of heavy payloads across its 30-500 mm/s speed range.

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 retract distance between 20 and 50 mm on heavy press machinery without physically replacing the cylinder or adding external mechanical stops.
Quickly adapt automated heavy-duty conveyor diverter arms to accommodate different product lengths by turning the rear adjuster screw during line setup.
Fine-tune the end-of-stroke position during initial equipment buildup to perfectly synchronize multi-cylinder motion without machining custom spacer blocks.
The rear adjuster acts purely as a travel stop to fine-tune the retract position; it does not lock the load. If your process requires true load-holding without continuous live air pressure, you should pivot to the SAIL air-released lock or BSAI clamp-lock series. Because the 50 mm nominal stroke is relatively short, side-loading is less of a concern than with longer strokes, though the substantial 40 mm rod naturally handles high bending moments. To match this ISO 15552 dimensionally interchangeable cylinder, ensure your setup specifies a 200 mm bore, 50 mm stroke, 30 mm adjustment range, PT G3/4 port, and the appropriate mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Quick checklist
At the maximum rated pressure of 1.0 MPa, it delivers a peak thrust of 3204 kgf.
The rear adjuster screw allows you to mechanically shorten the effective stroke from its 50 mm nominal length by up to 30 mm, resulting in a usable travel window of 20-50 mm. This stopper only sets the end position; it does not lock the load without live air pressure.
