The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X65-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 65mm 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 SAIJ200X65-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, designed for heavy-duty pneumatic applications. It features a robust 40 mm carbon steel rod and PT tapered ports. By integrating an external adjusting screw at the rear, this model allows you to fine-tune the effective travel to a precise 45-65 mm window during commissioning without swapping out the entire unit.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear stopper lets you dial in the exact end position, remember it acts strictly as a travel stop and does not hold 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.

Dial in the exact 45-65 mm travel window during heavy press commissioning to accommodate material thickness variations without adding external stoppers.
Quickly adjust the end-stop position on a conveyor diverting system when switching between different large pallet sizes on the production line.
Fine-tune the retraction point of heavy tooling during initial machine setup, ensuring precise alignment before locking down the sequence.
Choose this 200 mm bore cylinder when your application requires extreme force, such as 15708 N at 0.5 MPa, combined with precise end-position tuning. If your setup demands less push force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which may better suit medium-heavy loads. The adjustable stroke is specifically beneficial for product-size changeovers on a line, allowing operators to set variable end stops on the fly rather than machining external stop blocks.
When integrating this cylinder, note that the rear adjuster and the variable air cushions manage deceleration but cannot hold a load without continuous air. For load-holding requirements without live pressure, consider an external rod lock or explore related AirTAC types like the SAIL or BSAI. This SAIJ model supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. It operates at speeds of 30-500 mm/s.
Quick checklist
At the maximum pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 65 mm nominal stroke by up to 20 mm. This creates a usable travel window of 45-65 mm for fine-tuning the end position at commissioning.
