Airtac MKJ Adjustable Cylinder MKJ20X10-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ20X10-10 is a genuine MK multi-mount cylinder (adjustable stroke), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 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 MKJ20X10-10
The MKJ20X10-10 is an AirTAC MKJ adjustable-stroke multi-mount cylinder: double acting, 20 mm bore, 10 mm stroke plus a 10 mm adjustable range, and a no-rotating rod. Its compact square body fixes from 6 directions (front, back, left, right, top, bottom) and mounts side by side to save space, with magnetic-switch slots around the body and a bumper cushion. At 0.5 MPa this bore gives about 157.1 N of push-side thrust, enough for light clamping, gating and positioning jobs in tight footprints.
This is a genuine AirTAC part. The MK family is the no-rotating version of the MD multi-mount range: a fixed rod, plate and brass bushing stop the piston rod turning, which the standard MD body does not do. The trailing S on this SKU means a magnet is fitted for switch detection. We confirm dimensions, weights and sizing for your exact configuration 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 20 mm bore when you need roughly 157.1 N of push thrust at 0.5 MPa (the pull side is lower). Pick MK over MD when the rod must not rotate; MD allows rotation. Acting options are double acting (MK), single push (MSK), single pull (MTK), double rod (MKD) and adjustable stroke (MKJ). The standard bore-20 stroke table runs up to 60 mm; this SKU carries a short 10 mm stroke plus a 10 mm adjustable range, which keeps the cover compact. A long stroke extends the cover beyond the body, so avoid over-long strokes where you can. Magnet: this SKU carries the S suffix. Ports are M5x0.8 with PT threads on this SKU; G threads are selectable. Route side-load limits to us.
Applications
Compact clamp on a fixture
Clamps brackets or trays on a test or assembly fixture; the 6-direction fixing suits tight fixture faces and the short 10 mm stroke keeps the body low.
Stopper for small totes
Acts as a stopper for small totes on a conveyor; the no-rotating rod holds the stopper blade square and side-by-side mounting fits narrow frames.
Pick-and-place orientation
Drives a small pick-and-place plate where the part must not twist; the fixed rod and no-rotating plate keep orientation through the 10-20 mm travel.
FAQ
What does the -10 in MKJ20X10-10 mean?
It is the adjustable range: up to 10 mm of extra travel on top of the 10 mm base stroke, set within the standard 10, 20 or 30 mm options. The trailing S also tells you a magnet is fitted on this SKU for switch detection.
When should I pick the MK no-rotating version over the standard MD?
When the rod must not turn: a fixed rod and no-rotating plate stop rotation, keeping plates, stopper blades and gripper brackets square - the standard MD body allows rotation. Side-load limits and exact dimensions for your stroke come from the datasheet; we can confirm them on request.
