Airtac MKJ Adjustable Cylinder MKJ25X5-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ25X5-10 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 MKJ25X5-10
The MKJ25X5-10 is an AirTAC multi-mount cylinder with an adjustable stroke: a compact square-bodied, no-rotating cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side to save space. With a 25 mm bore in double-acting, no-rotating configuration, it delivers a theoretical push force of 245.4 N at 0.5 MPa, and the bumper cushions the piston at the end of travel. The short 5 mm stroke with a 10 mm adjustable range on top suits short, tunable moves.
This is a genuine AirTAC part. The MK family is the no-rotating version of the multi-mount range (the MD family is the standard type), so this model suits jobs where the rod must not rotate. This SKU has no trailing S, so it is supplied without a magnet. Dimensions and sizing details vary with the stroke, so confirm them 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
Choose the 25 mm bore when your clamp or push job needs roughly 245.4 N of theoretical thrust at 0.5 MPa. Pick MK when the rod must not turn, or MD when rotation does not matter. This is the adjustable-stroke version: the 5 mm stroke carries a 10 mm adjustable range on top, letting you tune the throw without redesigning the fixture. Note the short cover - strokes beyond the bore 25 table (up to 60 mm for double acting) can compromise guidance. Add the trailing S if you need a magnet, and choose PT (blank) or G thread; bore 25 uses M5x0.8 ports. Route side-load questions to us.
Applications
Fine part positioning
Nudge parts into position on an assembly jig with the short 5 mm stroke and 10 mm adjustable range, tuning the throw to the part without reworking the fixture.
Small-parts ejection
Eject or press small pins and inserts from a nest: about 245.4 N of push at 0.5 MPa, with the no-rotating rod keeping the tooling face square.
Fine-adjust stopper
Act as a fine-adjust stopper on a fixture or conveyor, fixed from any of six directions and adjusted over the 10 mm range to suit the part height.
FAQ
How much force does the 25 mm bore deliver?
As a double-acting MK cylinder, this 25 mm bore gives a theoretical push force of 245.4 N at 0.5 MPa on the push side (the pull side is lower). Operating pressure for this bore is 0.15-1.0 MPa (22-145 psi).
Why such a short stroke, and what adjusts?
The 5 mm stroke suits short clamp, eject or position moves, and the MKJ adjustable-stroke design adds a 10 mm adjustable range on top. Keep strokes within the bore's table - the short cover means over-long strokes compromise guidance - and confirm dimensions and side-load limits from the datasheet.
