The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX280-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 280mm 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 SAIJ160X280-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stopper, allowing you to dial back the nominal 280 mm stroke by up to 100 mm. This yields a highly flexible usable travel window of 180 to 280 mm, which is ideal for accommodating multiple product formats on a single piece of machinery without physically swapping the actuator. Built with a SUS304 stainless steel rod, it handles aggressive washdown environments while delivering a robust 10053 N pull force at 0.5 MPa.
This bore size features a G3/4 PT port and a 50 mm air cushion at both ends to manage heavy kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-travel detection. The rear adjuster acts purely as a travel stop to set deceleration limits, so it will not hold a load if air pressure is lost.

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.

Adjust the travel window from 180 to 280 mm on packaging lines to handle different carton sizes without physically replacing the cylinder or repositioning hard stops.
Dial in the exact retraction end-point during machine setup to perfect timing sequences, avoiding the need to machine custom spacer blocks.
An adjustable stroke is preferred over a fixed SAI cylinder when you need in-line commissioning flexibility to fine-tune end positions during machine setup or product changeover. The rear screw allows you to trim the travel distance precisely without adding external stops.
Because the 280 mm stroke is substantial, the 40 mm rod diameter and M36x2 thread provide rigidity, but you should still use an external guide to prevent excessive side loading on the piston. For load-holding requirements without live air pressure, this actuator cannot lock in place; you must integrate an external pilot-operated check valve or select a related SAIL or BSAI series cylinder. This unit mounts via Basic, FA, LB, TC, FTC, TCM1, or TCM2 interfaces, omitting FB, CA, CB, and CR options.
Quick checklist
At 0.7 MPa, the push force increases to 14074 N.
The rear adjusting screw acts as a mechanical stop that can shorten the 280 mm nominal stroke by up to 100 mm, providing an effective travel range of 180 to 280 mm. It only sets the travel end and deceleration point; it does not lock the load without continuous air pressure.
