Airtac MKJ Adjustable Cylinder MKJ20X15-10S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ20X15-10S 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 MKJ20X15-10S
The AirTAC MKJ series is a compact square-body multi-mount cylinder that fixes from six directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space. This MKJ20X15-10S is a double-acting no-rotating model with a 20 mm bore, a 15 mm stroke and an extra 10 mm adjustable range, producing about 157.1 N of theoretical push thrust at 0.5 MPa. Cushioning is by bumper, giving a simple, solid stop at each end.
This is a genuine AirTAC part. The MK family is the no-rotating version of the multi-mount range - a plate, brass bushing and fixed rod stop the rod turning - while the MD family is the standard variant. The trailing S on this SKU means a magnet is built in for switch position detection; 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
Match the bore to the thrust: this 20 mm bore gives 157.1 N push at 0.5 MPa (the pull side is lower); go to 25 mm or 32 mm for higher force. Select MKJ to prevent rod rotation, or MD where rotation is acceptable. The MKJ design adds a 10 mm adjustable range on top of the 15 mm stroke; double-acting strokes for this bore reach up to 60 mm, but the short compact covers caution against an over-long stroke. The S suffix means this SKU includes the magnet - the non-S version does not. Thread is PT with G available; route side-load questions to us, as the figure comes from the datasheet.
Applications
Gate and stopper control
Fitted on a conveyor line, the short adjustable stroke raises or lowers a stopper blade to hold and release cartons, with the no-rotating rod keeping the blade square.
Lab automation positioning
In compact benchtop automation, the magnet allows end-position sensing while the six-way fixing lets the cylinder be tucked under or beside a small parts nest.
Sorting chute diverters
Rows of units mounted side by side along a sortation chute flip diverter flaps between lanes, saving space in tight material-handling layouts.
FAQ
What does the S in MKJ20X15-10S indicate?
The trailing S means this cylinder is supplied with a built-in magnet, allowing magnetic switch detection of piston position. The same code without the S is supplied without a magnet, so pick the suffix that matches your control requirement.
Is a long stroke possible on this compact cylinder?
Double-acting strokes for the 20 mm bore run up to 60 mm in the table, but the compact covers are not designed for an over-long stroke, so keep the stroke short for best results. Confirm exact dimensions and allowable side-load from the datasheet for your stroke.
