The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 105mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAIJ80X105-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5 MPa and features a 25mm carbon steel piston rod with an M20x1.5 thread. By turning the rear screw, you achieve a usable travel window of 65-105mm, allowing precise end-position tuning without swapping hardware.
This extruded aluminum barrel utilizes a PT tapered G3/8 port and includes variable air cushions at both ends to decelerate the load smoothly. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear stopper sets the retract distance but does not lock the load; for dead-pilot holding, consider SAIL or BSAI variants.

Dial in the 65-105mm stroke window during format changes on packaging lines without bolting on new external stops.
Fine-tune the retract distance at commissioning to compensate for mechanical wear or sensor variance.
Leverage the 2513N push force to seat components, using the adjustable stop to prevent over-travel.
Choose this 80mm bore when an application requires higher thrust than a 63mm cylinder (which provides 1559N at 0.5 MPa) but has spatial constraints limiting a 100mm bore. The 40mm adjustment range is ideal for product changeovers on a packaging line, letting operators dial in the exact 65-105mm stroke on the fly instead of installing external physical stops.
When replacing an ISO 15552 cylinder, verify the 105mm stroke, 40mm adjuster, PT G3/8 port, and required mounting bracket. Because the stroke is 105mm, the 25mm rod handles side loads well, but any application approaching the 30-800mm/s speed range should still use an external guide to prevent binding.
Quick checklist
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the nominal 105mm stroke by up to 40mm. This creates a usable travel window of 65-105mm, which can be fine-tuned during setup without replacing the cylinder.
