Airtac MKJ Adjustable Cylinder MKJ25X15-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ25X15-10 is a genuine MK multi-mount cylinder (adjustable stroke), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 245.4 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 MKJ25X15-10
The MKJ25X15-10 is a 25 mm bore adjustable-stroke multi-mount cylinder with a 15 mm base stroke plus a 10 mm adjustable range, double acting for powered movement in both directions. The square body fixes from six directions - front, back, left, right, top and bottom - and units can be mounted side by side to save space in tight machine layouts, with magnetic-switch slots machined around the body. The cushion is a bumper, and at 0.5 MPa this bore delivers a theoretical push force of 245.4 N.
This is a genuine AirTAC part. The MK family is the no-rotating type: a plate, bushing and fixed rod stop the piston rod from turning, unlike the standard MD family where rod rotation is allowed. As the SKU shows no S suffix, this model comes without a magnetic piston. Dimensions vary with stroke, so confirm sizing and detailed dimensions from the datasheet, which we can supply 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
Choose the 25 mm bore when you need roughly 245.4 N of theoretical push at 0.5 MPa; smaller bores in the range give less force. MKJ is the adjustable-stroke no-rotating choice, so use it where the rod must not rotate. This unit is double acting, and the 15 mm stroke plus a 10 mm adjustable range sits well inside the 60 mm maximum for this bore - note the short body cover, which cautions against over-long strokes. There is no magnet on this SKU; add the S suffix if you need switch detection. Ports are M5x0.8 with PT thread, with G available as an option. Side-load limits are not quoted here - confirm from the datasheet or ask us.
Applications
Jig positioning
Extend and retract a locating pin into drilled jigs. The no-rotating rod keeps the pin orientation fixed stroke after stroke, and the 245.4 N push at 0.5 MPa seats parts repeatably.
Small-parts clamping
Clamp small components in a machining or assembly fixture. The six-direction fixing lets the cylinder bolt into cramped fixture plates, and the adjustable range trims the clamp position to the part.
Gate and stopper duty
Raise a stopper or deflect gate on a light conveyor line. Units mount side by side for multi-lane layouts, and the bumper cushion softens the stop at the end of each 15 mm stroke.
FAQ
What does the -10 in MKJ25X15-10 mean?
It is the adjustable stroke. The cylinder has a 15 mm base stroke plus a 10 mm adjustable range, so the effective stroke can be set anywhere within 10 mm on top of the base. The 25 is the bore in mm. Because the SKU has no S suffix, no magnet is fitted.
How does the six-direction mounting help in a tight layout?
The square body fixes from the front, back, left, right, top and bottom, so you can bolt it down from whichever face is accessible and line units up side by side to save space. Keep strokes within what the short cover allows, and confirm dimensions and side-load limits from the datasheet before finalising the layout.
