Airtac MKJ Adjustable Cylinder MKJ32X60-20

This MKJ32X60-20 is AirTAC's adjustable-stroke, no-rotating multi-mount cylinder in a 32 mm bore: a compact square body that fixes from six directions (front, back, left, right, top and bottom) and mounts side by side so neighboring cylinders share the same pitch and save space. Double acting on filtered air, it produces 402.1 N of theoretical push force at 0.5 MPa within an operating pressure of 0.15-1.0 MPa (22-145 psi), with cushioning by bumper and a working temperature of -20 to 70 C. The -20 in the code adds a 20 mm adjustment range on top of the 60 mm stroke for setting the end of travel precisely.

This is a genuine AirTAC part. In the MK family a no-rotating plate, brass bushing and fixed rod (typical construction) prevent the rod from turning, which is the key difference from the standard MD family. As coded, this unit has no magnet; magnet versions carry a trailing S if position detection is later needed, and the optional high-temperature seal material extends the range to 0-150 C. We confirm dimensions and detailed sizing from the datasheet on request.

The 32 mm bore is the strongest in the MKJ range, delivering 402.1 N push and 345.6 N pull at 0.5 MPa, so choose it when clamp or push force is the deciding factor. Select MK over MD whenever the rod or a mounted plate must stay rotationally fixed. This is a double-acting adjustable model: air powers both directions and the -20 gives a 20 mm adjustment on top of the 60 mm stroke. The SKU without an S carries no magnet; choose the S suffix when a switch slot will be used. The port thread is PT by default with G offered as an option. Keep the stroke within the bore's table - the short covers are not meant for stretched-out strokes - and send side-load questions to us.
