The AirTAC Airtac MKJ Adjustable Cylinder MKJ6X20-10S is a genuine MK multi-mount cylinder (adjustable stroke), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 14.1 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.
The MKJ6X20-10S is an adjustable-stroke, no-rotating multi-mount cylinder from AirTAC's MK family. Its compact square body fixes from six directions (front, back, left, right, top and bottom), so it can be bolted face-down in a jig or stood side by side with neighbours to save space, and magnetic-switch slots run around the body. This 6 mm bore is double acting and pushes with a theoretical 14.1 N at 0.5 MPa (10.6 N on the pull side) over the 20 mm stroke, with a 10 mm adjustable range for trimming the effective stroke at setup. Cushioning is a bumper, operating pressure is 0.2-1.0 MPa (28-145 psi), and speed is 30-500 mm/s.
This is a genuine AirTAC part. Where the MD family is the standard multi-mount design, MK cylinders add a no-rotating plate, bushing and fixed rod that stop the piston rod turning, which suits loads that must hold orientation. The trailing S in this SKU shows the magnet is fitted; ports are M5x0.8 with PT thread. We confirm dimensions, exact thrust 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.
Choose this SKU when you need the smallest MKJ bore with adjustable stroke: 6 mm gives about 14.1 N push (10.6 N pull) at 0.5 MPa, so size up to 10, 16, 20, 25 or 32 mm if your clamp or press needs more force. MKJ is double acting with a no-rotating rod; if rotation is harmless and you want the standard body, pick MD instead. The 20 mm base stroke sits well inside the 35 mm maximum for a 6 mm double-acting bore, and the 10 mm adjustable range is set at installation. The trailing S means magnet; without it, switch reading is not possible. Thread is PT by default (G available on request), and side-load limits come from the datasheet, so confirm with us.
Bolt the cylinder top-down into a fixture to clamp tiny components during glue, mark or test steps; the no-rotating rod keeps the clamp pad facing the same way every cycle.
Mount through the conveyor side frame as a pop-up gate that stops or diverts small parts; the 6-direction fixing lets the body sit flush under the belt line.
Use the adjustable stroke to set an exact part-present position in a small pick-and-place head, with the magnet fitted for end-of-stroke switch feedback.
It is the adjustable stroke range in millimetres, added on top of the 20 mm base stroke, so you can trim the effective stroke by up to 10 mm at setup. MKJ is the adjustable-stroke, double-acting, no-rotating variant; the trailing S shows the magnet is fitted, and this bore uses M5x0.8 ports with PT thread.
The MK body adds a plate, bushing and fixed rod that stop the piston rod turning, so clamp pads, gates and carriers hold their orientation without an external guide. Because the square body fixes from six directions and mounts side by side, the whole assembly stays short and compact; confirm side-load limits and dimensions from the datasheet.
