Airtac MKJ Adjustable Cylinder MKJ10X30-20
The AirTAC Airtac MKJ Adjustable Cylinder MKJ10X30-20 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 MKJ10X30-20
The MKJ10X30-20 is an AirTAC multi-mount cylinder with a compact square body that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side to save space. This no-rotating, adjustable-stroke version pairs a 10 mm bore and 30 mm base stroke with a generous 20 mm adjustable range, giving flexibility when the working position must be dialled in on the machine. Double acting, it produces a theoretical push force of about 39.3 N at 0.5 MPa, and cushioning is by a bumper.
This is a genuine AirTAC part. In the MK family a no-rotating plate, brass bushing and fixed rod stop the piston rod from turning, whereas the standard MD family permits normal rotation. The code has no trailing S, so this SKU is supplied without a magnet. We can 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
Start from thrust: at 0.5 MPa this 10 mm bore gives a theoretical push of 39.3 N (pull is lower), right for light clamping, stopping and sliding duties. The MKJ variant suits jobs where rod rotation must be prevented and the stroke needs on-machine adjustment - this code carries a 20 mm adjustable range over the 30 mm base stroke, comfortably within the 35 mm stroke limit for a double acting 10 mm bore. Avoid stretching the stroke beyond the bore's table; the compact body is not built for it. No magnet in this code (choose the S version for switching) and PT thread as standard, G on request. Confirm side-load capability from the datasheet with us.
Applications
Adjustable part stopper at a work station
Extend the non-rotating rod to halt parts at a manual or automatic station; the 20 mm adjustable range lets operators re-set the stop position for different product sizes without shimming.
Height-set positioning in test rigs
Fix the body from above or below in a fixture and use the adjustable stroke to set a precise probe or sensor height, with the fixed rod preventing twist in the carried element.
Side-by-side diverting fingers on a conveyor
Mount several cylinders flush along a conveyor edge to push small items off the line; the square bodies sit side by side in tight frames and the bumper cushions each divert.
FAQ
What is the difference between the -10 and -20 adjustable ranges on this bore?
Both models share the MKJ no-rotating adjustable-stroke design, a 10 mm bore and a 30 mm base stroke; the number after the dash is the adjustable range added on top. MKJ10X30-20 therefore gives a 20 mm tuning window instead of 10 mm, useful when the end position must be re-set across a wider span on the machine.
What stops the rod from rotating, and does it need lubrication?
In the MK family a no-rotating plate, brass bushing and fixed rod hold the rod against turning, keeping pads and tooling square. The cylinder runs on air filtered to 40 um with high guide precision and no added lubricant required; if your application carries side load, confirm allowable values from the datasheet before relying on them.
