Airtac MKJ Adjustable Cylinder MKJ10X30-20S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ10X30-20S 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 MKJ10X30-20S
The MKJ10X30-20S is an AirTAC MK-family multi-mount cylinder: a compact square-body actuator you can fix from 6 directions (front, back, left, right, top and bottom) and mount side by side with neighbours to save panel space. Magnetic-switch slots are machined around the body, guide precision is high, and no added lubricant is needed. This unit is double acting, no-rotating, with a 10 mm bore and a 30 mm stroke that carries an extra 20 mm of adjustable stroke, so the effective stroke can be fine-trimmed in place. At 0.5 MPa the bore-10 push side gives about 39.3 N of theoretical thrust, and cushioning is a bumper.
This is a genuine AirTAC part. The MK family prevents rod rotation with a fixed rod, no-rotating plate and brass bushing, while the MD family is the standard version that allows rotation - choose MK when the load must not turn. Magnet is fitted on this SKU, as shown by the trailing S. Operating pressure is 0.2-1.0 MPa (28-145 psi) for this bore, the medium is air filtered to 40 um, and temperature range is -20 to 70 C (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
Bore sets thrust: this 10 mm bore delivers about 39.3 N push at 0.5 MPa (double acting), so pick a larger bore if your work needs more force. MK is the no-rotating family - rod rotation is prevented - while MD is the standard family where rotation is allowed. Acting type: this is a double-acting MKJ adjustable-stroke unit; single-acting push (MSK) and pull (MTK), double-rod (MKD) and standard (MK) variants also exist. The 30 mm stroke sits inside the bore-10 double-acting table (up to 35 mm), and the J variant adds 10, 20 or 30 mm of adjustable range on top - this SKU adds 20 mm. Keep the stroke short relative to the cover: an over-long stroke on a compact body is a common mis-selection. Trailing S means a magnet is fitted for switch sensing; thread on this SKU is PT (G is available). Side-load capacity is not quoted here - ask us and we will check the datasheet.
Applications
Small-parts clamping
Clamp small components in fixtures where the no-rotating rod keeps the clamp pad square to the part, and the 6-direction fixing lets the cylinder bolt into tight clamp positions.
Jig positioning
Push parts against a jig stop with the adjustable stroke trimmed to the exact position needed, mounting several MKJ cylinders side by side on a crowded jig plate.
Parts stopper on conveyors
Extend across a conveyor lane to stop or divert small parts; the compact square body fixes from the top or side and the rod will not twist under the load.
FAQ
What does the code MKJ10X30-20S mean?
MKJ is the MK-family adjustable-stroke variant (double acting, no-rotating), 10 is the bore in mm, 30 is the base stroke in mm, -20 is the 20 mm adjustable range added on top, and the trailing S means a magnet is fitted. No trailing G means PT thread. At 0.5 MPa this bore gives about 39.3 N push.
Where can I mount this cylinder and how far can the stroke go?
The square body fixes from 6 directions - front, back, left, right, top and bottom - and cylinders can sit side by side to save space. Note the compact cover: keep the stroke short and sensible for the bore rather than stretching it. Exact dimensions, side-load limits and stroke tables come from the datasheet, which we confirm on request.
