The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX1000-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ80X1000-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 960 mm from the 1000 mm nominal stroke. This specific configuration uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads.
Because the adjustment mechanism acts purely as a mechanical stop at the retract end, it does not lock the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE or DMSE switches for position feedback. With a 25 mm rod and M20x1.5 thread, this 1000 mm stroke unit benefits from an external guide to prevent excessive side-loading on the long unsupported piston rod.

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 position within the 960-1000 mm window when switching production lines to different product sizes without machining new hard stops.
Use the 1000 mm travel for large-format assembly tasks, relying on the rear adjuster to set precise end-of-stroke deceleration before the air cushion takes over.
The rear screw on this SAIJ allows a 40 mm commissioning adjustment window, which is ideal for product changeovers where a fixed-stroke SAI cylinder would require external stops. For load-holding without continuous air pressure, this cylinder is not a lock; you should consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 1000 mm stroke, PT G3/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Given the 1000 mm stroke, always use an external guide rail to support the load and protect the 25 mm rod from deflection.
Quick checklist
The maximum thrust is 513 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 960 to 1000 mm. The adjuster acts as a mechanical stop at the retract end and does not function as a lock to hold the load without air pressure.
