Airtac MKJ Adjustable Cylinder MKJ6X25-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ6X25-10 is a genuine MK multi-mount cylinder (adjustable stroke), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 14.1 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 MKJ6X25-10
The MKJ6X25-10 is an AirTAC multi-mount cylinder with a compact square body 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 no-rotating, double-acting unit has a 6 mm bore with a 25 mm stroke plus a 10 mm adjustable range, giving about 14.1 N of theoretical push force at 0.5 MPa for light clamping and positioning work. Cushioning is a bumper, the media is air filtered to 40 um, and it runs at 0.2-1.0 MPa (28-145 psi) over -20 to 70 C.
This is a genuine AirTAC part. The MK family uses a no-rotating plate, bushing and fixed rod to stop the piston rod turning, which this SKU provides without a magnet (no S suffix). Porting is M5x0.8 with PT thread. Dimensions and sizing details vary with stroke, so ask us and we will confirm them from the datasheet.

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 6 mm bore when your duty needs about 14.1 N of push at 0.5 MPa. MK prevents rod rotation while MD allows it, and this adjustable-stroke MKJ version is double acting with a 10 mm adjustable range on top of the 25 mm stroke; bore 6/10 double-acting strokes run up to 35 mm. This SKU has no magnet (no S suffix) and PT thread; a G-thread version and the S magnet option are listed separately. Keep the stroke modest - the short cover warns against over-long strokes - and route any side-load question to us.
Applications
Small-parts clamping
The fixed rod and no-rotating plate keep the pushing face square to the part, so the 6 mm bore clamps tiny components in fixtures without the rod twisting under load.
Slide-gate stopper
Mounted top or bottom on a conveyor line, the cylinder extends a stopper to halt small parts, with the 10 mm adjustable range dialling in the exact stop position.
Indexing fixture
Bolted side by side along an indexing jig, the compact square body advances each station precisely while the non-rotating rod keeps the index pin aligned.
FAQ
What does the -10 in MKJ6X25-10 mean?
MKJ is the AirTAC adjustable-stroke version of the MK no-rotating multi-mount cylinder. The code reads as a 6 mm bore, 25 mm stroke, with a 10 mm adjustable range on top, double acting, no magnet (no S suffix) and PT thread. A -20 version gives a 20 mm adjustable range, and the S suffix adds a magnet.
How does the no-rotating design help in tight layouts?
The MKJ body can be fixed from six directions and mounted side by side, and the built-in plate, bushing and fixed rod stop the rod from turning. That keeps push faces and attached plates aligned without external guides. For exact dimensions at your stroke, confirm from the datasheet, and check any side-load requirement with us.
