Airtac MDJ Adjustable Cylinder MDJ25X20-20
The AirTAC Airtac MDJ Adjustable Cylinder MDJ25X20-20 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 MDJ25X20-20
The AirTAC MDJ25X20-20 is a genuine AirTAC multi-mount cylinder, a compact square-body double-acting cylinder that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side to save space. The 25 mm bore with a 20 mm base stroke and a 20 mm adjustable-stroke range gives generous trim for end-position tuning. At 0.5 MPa the bore produces a theoretical push force of about 245.4 N (pull side about 206.2 N), and cushioning is a bumper.
This is a genuine AirTAC part in the standard MD family, so the rod is not constrained against rotation - for that you need the MK no-rotating family. This SKU carries no magnet designation, so it is supplied without a magnet, although switch slots are machined around the body. Ports are PT (M5x0.8 on this bore). 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 right choice around a 245.4 N theoretical push requirement at 0.5 MPa. As an MDJ double-acting cylinder it carries a 20 mm base stroke plus a 20 mm adjustable range, with bore 25 double-acting strokes running up to 60 mm in the table - but keep the stroke short where you can, since the short cover design cautions against over-long strokes. MD allows rod rotation; MK prevents it, so switch families if that matters. This SKU has no trailing S, so it comes without a magnet - add an S variant if switch detection is required. Thread here is PT; G is offered on request. Route side-load questions to us and we will confirm from the datasheet.
Applications
Press-fit assist
Fix the body vertically above a light press station and use the 245.4 N push force with the 20 mm adjustable range to seat small components consistently.
Part alignment before machining
Mount side-mounted on a fixture to nudge and square parts against a backstop; the compact body fits where long tie-rod cylinders cannot.
Gate diverter on small conveyors
Fix from the top or side of a narrow conveyor frame and swing a lightweight gate to divert small parts, with the bumper softening each stroke.
FAQ
How much force does the 25 mm bore produce on this cylinder?
As a double-acting cylinder, the push side gives a theoretical force of about 245.4 N at 0.5 MPa, and the pull side about 206.2 N. Operating pressure for the MD family is 0.15-1.0 MPa (22-145 psi). Actual usable force depends on your supply pressure and load conditions.
Why is there no magnet in the model name MDJ25X20-20?
A trailing S marks a cylinder supplied with a magnet. This SKU has no S, so it is supplied without a magnet - though magnetic-switch slots are still machined around the body. If you later need position detection, select the matching S variant instead.
