Airtac MKJ Adjustable Cylinder MKJ10X20-20S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ10X20-20S is a genuine MK multi-mount cylinder (adjustable stroke), 10 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 39.3 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 MKJ10X20-20S
The MKJ10X20-20S is a compact AirTAC multi-mount cylinder with a square body that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side to save space. As an MK no-rotating type, its fixed rod and plate stop the piston rod from turning, so the rod face stays oriented. The 10 mm bore and 20 mm stroke, extendable by a 20 mm adjustable range, produce about 39.3 N of theoretical push thrust at 0.5 MPa (33.0 N on the pull side), with a bumper for cushioning.
This is a genuine AirTAC part in the no-rotating MK family, the counterpart to the standard MD series. The trailing S in the code means this SKU includes a magnet for switch sensing in the slots around the body. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), with 1.5 MPa (215 psi) proof pressure and -20 to 70 C operation (0 to 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
Pick the 10 mm bore for jobs needing about 39.3 N of push at 0.5 MPa; bores 16-32 raise the thrust in the same square footprint. MK (this series) prevents rod rotation; MD allows it - match the series to whether your part must stay square. Acting types: double acting (this model), single push (MSK), single pull (MTK), double rod (MKD), adjustable stroke (MKJ). This SKU's 20 mm stroke carries a 20 mm adjustable range on top; keep the total within the short-stroke limits the compact covers impose. The trailing S adds the magnet; choose PT thread by default or G - confirm side-load limits and exact dimensions from the datasheet or ask us.
Applications
Stopper on a transfer line
Stop flowing parts at a station with a non-rotating stopper blade, and use the magnet signal to confirm the blade is fully retracted before parts resume.
Test station clamping
Hold small assemblies under a test probe in a bench-top fixture; the adjustable stroke sets clamping reach and the no-rotating rod keeps contact pads square.
Compact pick-and-place
Lower a suction or gripper head onto small parts where space is tight; the 6-way body mounting and side-by-side layout fit multi-axis compact gantries.
FAQ
How does MKJ10X20-20S differ from a standard MD cylinder of the same size?
Both are multi-mount cylinders, but MK is the no-rotating type: a fixed rod and plate stop the piston rod turning, so the rod face keeps its orientation - useful where a blade or pad must stay square. MD allows rotation. This SKU also has the S magnet and a 20 mm adjustable range on its 20 mm stroke.
What should I watch out for when applying this cylinder?
Keep the set stroke within the short-stroke capability of the compact covers - the design cautions against over-long strokes at this bore. Also confirm the exact overall dimensions for your set stroke from the datasheet, and check any side-load on the rod with us before finalising the fixture.
