Airtac MDJ Adjustable Cylinder MDJ25X10-10
The AirTAC Airtac MDJ Adjustable Cylinder MDJ25X10-10 is a genuine MD 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.

About the Airtac MDJ Adjustable Cylinder MDJ25X10-10
The MDJ25X10-10 is an AirTAC MD-series adjustable-stroke multi-mount cylinder with a 25 mm bore, a short 10 mm base stroke and a 10 mm adjustable range. Like all multi-mount cylinders, its compact square body fixes from 6 directions - front, back, left, right, top and bottom - and units sit side by side to save space, with magnetic-switch slots around the body and high guide precision needing no added lubrication. Double acting, it produces about 245.4 N of theoretical push thrust at 0.5 MPa (206.2 N on the pull side), and cushioning comes from a bumper.
This is a genuine AirTAC part. It belongs to the standard MD family; the MK family is the no-rotating counterpart, so this model permits normal rod rotation. The SKU has no trailing S, meaning it is supplied without a magnet. It runs at 0.15-1.0 MPa (22-145 psi) on air filtered to 40 um. We 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
The 25 mm bore is the choice when a short stroke must still deliver meaningful force - about 245.4 N theoretical push at 0.5 MPa - such as a firm clamp over 10 mm of travel. Pick MD if the rod may rotate, MK if it must not. The MDJ adjustable-stroke prefix adds a 10/20/30 mm range on top of the base stroke; this model pairs a 10 mm base stroke with the 10 mm range, ideal where travel must be fine-tuned in a very tight envelope. The compact body uses short covers, so resist stretching the stroke beyond the need - confirm dimensions with us from the datasheet. No magnet on this SKU (S adds one); PT threads fitted, G optional. Side-load questions come to us.
Applications
Small-parts clamping
A 10 mm base stroke with 10 mm of adjustment is made for clamping small parts in machining or assembly fixtures, and the 245.4 N push at 0.5 MPa gives a firm hold from a body only 25 mm across.
Jig positioning stops
Fixed from the top or side of a drill or assembly jig, the cylinder acts as an adjustable hard stop or pusher, with the 6-way mounting letting it bolt directly onto the jig face.
Conveyor stopper blades
Side-by-side multi-mount bodies make compact pop-up or end stops on narrow conveyors, where the short stroke is an advantage and the bumper cushions each part arrival.
FAQ
Is the MDJ25X10-10 single acting because the stroke is short?
No. The acting type comes from the prefix, not the stroke. MDJ means a double-acting adjustable-stroke cylinder, so air drives the rod both ways. Single-acting push types carry the MSD prefix and pull types MTD, and they operate at 0.2-1.0 MPa. This model runs at 0.15-1.0 MPa (22-145 psi) and has a bumper cushion.
What are the limits of a short-stroke compact cylinder like this?
The compact square body is built around short covers, which is why over-long strokes should be avoided - the 10 mm base stroke with a 10 mm adjustable range is the intended envelope. Overall dimensions depend on stroke, and allowable side-load is not quoted as a figure here, so confirm both from the datasheet before designing the fixture.
