The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX65-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 65mm 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 SAIJ32X65-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 25 and 65 mm without adding external stops. The PT tapered ports ensure a tight pneumatic seal during high-speed operations.
This 32 mm bore variant includes a built-in magnet for position sensing with CMSE reed or DMSE solid-state switches. It utilizes a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The rear adjuster acts purely as a travel stop for end-position tuning, not a lock, meaning live air is required to hold the load.

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 25 to 65 mm travel window during initial machine commissioning to perfectly align picking heads without swapping hardware.
Quickly shorten the effective stroke on a packaging line when switching to a smaller product size, using the 40 mm rear adjustment range.
Establish a precise, repeatable retract end-stop for a light-load assembly press, utilizing the 345 N pull force at 0.7 MPa.
Choose this 32 mm bore model when an application requires precise end-position tuning during commissioning or product changeover, offering a 25-65 mm adjustable travel window. Conversely, if lower force is acceptable, the 32 mm provides a compact footprint.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 65 mm nominal stroke, 40 mm adjustment range, PT port threads, and the -S magnet requirement. Remember that the rear adjuster and air cushions only set the travel end and decelerate the piston; they do not hold the load without live air. For true load-holding without continuous pressure, consider the SAIL or BSAI series instead.
Quick checklist
The rear adjuster screw allows you to mechanically shorten the 65 mm nominal stroke by up to 40 mm, creating a usable travel window of 25 to 65 mm. This stopper only sets the end position and does not lock the load without live air.
