The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX275-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 275mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ32X275-100 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. With a nominal 275mm stroke and a 100mm adjustment range, it provides a usable travel window of 175-275mm, allowing you to dial in the exact retract end-position during commissioning without swapping the cylinder.
The rear adjuster acts purely as a mechanical stop to fine-tune the travel end and works in tandem with the variable air cushions at both ends; it is not a lock and will not hold a load without live air. This extruded aluminum profile barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches (requires a magnet, not specified here). It uses a PT tapered G1/8 port and supports a speed range of 30-800 mm/s.

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.

Quickly fine-tune the retract distance within the 175-275mm window when switching between product sizes on a packaging line.
Set exact end-of-stroke positions during commissioning without machining external stopper blocks.
Choose this 32mm bore adjustable-stroke cylinder when your machine requires precise end-position tuning over a wide 175-275mm window, avoiding the need to bolt on external stops or maintain multiple fixed-stroke SAI cylinders for product changeovers. Conversely, if you need less force in a smaller footprint, the 32mm bore is the optimal baseline.
Because the 275mm stroke is relatively long for a 32mm bore, the 12mm rod and M10x1.25 thread can carry some side load, but an external guide is recommended to prevent rod binding. For load-holding without continuous air pressure, pair this cylinder with an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series instead. To replace an ISO 15552 cylinder, match the 32mm bore, 275mm stroke, 100mm adjustment, PT G1/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2 — omitting FB, CA, CB, CR).
Quick checklist
It features a rear adjusting screw that allows you to mechanically shorten the effective stroke by up to 100mm. This creates a usable travel window of 175-275mm, letting you fine-tune the retract end-position at commissioning. The adjuster functions as a travel stop, not a lock, so it cannot hold a load without live air pressure.
At 0.7 MPa, the push force increases to 563N. The operational speed range is 30-800 mm/s.
