Airtac MKJ Adjustable Cylinder MKJ20X15-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ20X15-10 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 MKJ20X15-10
The AirTAC MKJ series is a compact square-body multi-mount cylinder that can be fixed from six directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space. This MKJ20X15-10 is a double-acting no-rotating model with a 20 mm bore, a 15 mm stroke and an extra 10 mm adjustable range, giving about 157.1 N of theoretical push thrust at 0.5 MPa. Cushioning is a bumper, keeping the stop simple and dependable.
This is a genuine AirTAC part. Where the MD family is the standard multi-mount, the MK family adds a no-rotating plate, bushing and fixed rod so the rod cannot turn - ideal where a fixture must stay oriented. This SKU has no trailing S, so it is supplied without a magnet; dimensions and sizing can be confirmed 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
Size the bore to your thrust: the 20 mm bore delivers 157.1 N push at 0.5 MPa, with a lower pull figure; step up to 25 mm or 32 mm for more force. Choose MKJ when the rod must not rotate, or MD when rotation is allowed. This MKJ combines a 15 mm stroke with a 10 mm adjustable range; double-acting strokes for this bore run up to 60 mm, but remember the compact covers are not meant for an over-long stroke. With no trailing S the cylinder comes without a magnet; thread is PT as standard, with G as the option. Allowable side-load is application-dependent - check it with us from the datasheet.
Applications
Pick-and-place Z-stroke
On a compact pick-and-place head, the no-rotating rod keeps the gripper plate from spinning as it lifts and lowers small components between stations.
Indexing fixture actuation
The adjustable 10 mm range fine-tunes the indexing movement of an indexing fixture, while six-direction fixing lets the cylinder bolt directly into tight tooling.
Press-fit assist station
Mounted side by side on a small assembly bench, twin units deliver the short controlled push needed to seat bearings or bushings in light press-fit work.
FAQ
Should I choose the MKJ no-rotating cylinder or the standard MD version?
If the rod or anything fixed to it must stay square - a plate, gripper or stop - choose the MKJ, whose plate and fixed rod prevent rotation. If rotation does not matter, the standard MD multi-mount family is the simpler choice for the same compact body.
Can this cylinder be fitted from any face of the body?
Yes. The square body fixes from six directions - front, back, left, right, top and bottom - and multiple units can sit side by side to save space. Stroke-specific dimensions and side-load limits should be confirmed from the datasheet before final design.
