Airtac MKJ Adjustable Cylinder MKJ32X20-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X20-10 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 MKJ32X20-10
The MKJ32X20-10 is an AirTAC multi-mount cylinder: a compact square-body unit that can be fixed from six directions (front, back, left, right, top and bottom) and mounted side by side to save space. This is the adjustable-stroke, no-rotating variant, double acting, with a 32 mm bore, a 20 mm base stroke and an added 10 mm adjustable range. On filtered air (40 um) it runs at 30-500 mm/s, operating pressure is 0.15-1.0 MPa (22-145 psi), and cushioning is a bumper. At 0.5 MPa the theoretical push force at this bore is 402.1 N, with 345.6 N on the pull side.
This is a genuine AirTAC part from the MK family, which uses a fixed rod and no-rotating plate to stop the piston rod turning; the standard MD family allows rotation instead. This SKU has no magnet (only model codes ending in S include the magnet). Temperature range is -20 to 70 C, or up to 0-150 C only with the optional high-temperature seal material. We confirm 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
Size the bore for thrust: at 32 mm the theoretical push force is 402.1 N at 0.5 MPa (345.6 N pull). MK prevents rod rotation, MD allows it. This code is double acting with a 20 mm base stroke plus a 10 mm adjustable range; MDJ/MKJ adjustable strokes add 10, 20 or 30 mm. Double-acting strokes for bore 32 run up to 60 mm, but keep the stroke short since long strokes over-extend the covers. Magnet is only on SKUs ending in S. Port thread is PT (default) or G; on bore 32 the port is 1/8". Allowable side-load is not quoted here: confirm from the datasheet or ask us.
Applications
Height setting of a lift-and-locate pin
The adjustable stroke trims the lift height of a locating pin under a pallet, while the non-turning rod keeps the pin aligned so it always enters the same bushing.
Eject pin on a small stamping or forming die
A short 20 mm stroke with 402.1 N of push at 0.5 MPa clears finished pieces from a die nest, and the square body bolts directly to the die shoe from any of six faces.
Gate control on AGV docking stations
Mounted side by side along the dock edge, these cylinders drive short locking gates for automated guided vehicles; the fixed rod keeps the gate hook from rotating under load.
FAQ
Why choose MKJ over a standard MK cylinder here?
The MKJ is the adjustable-stroke MK variant: this model has a 20 mm base stroke with an extra 10 mm adjustable range, so the end of stroke can be set within that window. It keeps the MK no-rotating fixed rod and plate, unlike the MD family where the rod can turn.
What should I check before ordering a long stroke?
These compact cylinders use short covers, so an over-long stroke should be avoided; double-acting strokes for bore 32 run up to 60 mm. Overall dimensions change with stroke, and allowable side-load is not a published number here, so confirm both from the datasheet or ask us before finalizing.
