Airtac MKJ Adjustable Cylinder MKJ32X40-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X40-10 is a genuine MK multi-mount cylinder (adjustable stroke), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 N of push force at 0.5 MPa. A bumper cushions the impact. As an MK unit a fixed rod stops the piston rod rotating.

About the Airtac MKJ Adjustable Cylinder MKJ32X40-10
The MKJ32X40-10 is an AirTAC adjustable-stroke multi-mount cylinder that fixes from six directions (front, back, left, right, top and bottom) and mounts side by side to save space on compact machines. With a 32 mm bore and a 40 mm base stroke plus a 10 mm adjustable range, it is a double-acting, no-rotating cylinder that delivers about 402.1 N of theoretical push force at 0.5 MPa. Cushioning is a bumper, and magnetic-switch slots are machined around the body (this SKU is built without a magnet).
This is a genuine AirTAC part. The MK family keeps the piston rod from turning via a no-rotating plate, bushing and fixed rod, unlike the standard MD family where rotation is allowed. Operating pressure for this 32 mm bore is 0.15-1.0 MPa (22-145 psi) with air filtered to 40 um, and the media temperature range is -20 to 70 C (up to 0-150 C only with the optional high-temperature seal material). We confirm exact dimensions and sizing from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Choose the 32 mm bore when you need the largest thrust in this range: 402.1 N push or 345.6 N pull at 0.5 MPa. Pick MK over MD when the rod must not rotate; pick MD when rotation is acceptable. The MKJ adjustable-stroke variant adds a 10, 20 or 30 mm adjustable range on top of the base stroke (this SKU: 40 mm base plus 10 mm adjustable; bore 32 double-acting strokes run up to 60 mm). This SKU has no magnet (no S suffix) and a PT thread; a G thread and the magnet option (S) are available on request. Note the short covers favor short strokes, so avoid over-long strokes, and confirm side-load limits with us from the datasheet.
Applications
Rotating fixture clamp
The no-rotating rod clamps a fixture flat face-on so the plate does not twist the workpiece, with the six-direction body fix letting the cylinder bolt into a tight fixture cavity.
Pick-and-place push
Mounted side by side on a compact gantry head, the 32 mm bore gives 402.1 N of push at 0.5 MPa to seat parts squarely, and the non-turning rod keeps the gripper aligned.
Conveyor stopper gate
Fixed from the top or side of a conveyor frame, the adjustable stroke dials in the stopper height and the no-rotating rod keeps the stop plate square to oncoming parts.
FAQ
What does the -10 in MKJ32X40-10 mean?
MKJ is the AirTAC adjustable-stroke variant of the no-rotating MK multi-mount cylinder. The code decodes as a 32 mm bore with a 40 mm base stroke plus a 10 mm adjustable range, double acting, no magnet (no S suffix) and PT thread. The adjustable range is offered as 10, 20 or 30 mm on top of the base stroke.
How many ways can I mount this cylinder, and where do I get exact dimensions?
The multi-mount square body fixes from six directions: front, back, left, right, top and bottom, so cylinders can sit side by side to save space. Overall dimensions and side-load limits vary by stroke, so confirm them from the datasheet or ask us and we will send the specifics.
