About the Airtac MDJ Adjustable Cylinder MDJ25X30-30
The MDJ25X30-30 is an AirTAC MD-series multi-mount cylinder with an adjustable stroke: a 30 mm base stroke plus a 30 mm adjustable range, giving a wide tuning window for positioning and stop applications. The compact square body fixes from six directions - front, back, left, right, top and bottom - and cylinders mount side by side to save space, with magnetic-switch slots around the body. This double-acting 25 mm bore version delivers about 245.4 N of theoretical push force at 0.5 MPa, runs at 30-500 mm/s, works on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), and is cushioned by a bumper.
This is a genuine AirTAC part. MD is the standard multi-mount family, so the rod is free to rotate unless your fixture prevents it; only the MK family adds a no-rotating plate. With no trailing S in the code, this SKU does not include the magnet. We will confirm dimensions, weight and sizing details 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
Size the bore to your thrust: the 25 mm bore pushes about 245.4 N at 0.5 MPa on the push side, with less on the pull side. Choose MD when rod rotation is allowed and MK when rotation must be stopped. Acting choices cover double acting, single push (MSD), single pull (MTD), double rod (MDD) and this adjustable-stroke MDJ, which adds a 10, 20 or 30 mm adjustable range; double-acting strokes in this bore run up to 60 mm. Add a trailing S if you want the magnet; thread is PT (default) or G. Keep the stroke within what the short body cover allows - for long strokes or side-load questions, ask us or check the datasheet.
Applications
Adjustable-height ejector
Fitted under a small chute or lift station, the 30 mm adjustable range lets the operator set the eject stroke precisely without changing cylinders between product variants.
Slide positioning on a transfer rail
Mounted side by side along a transfer rail, the compact square body fixes from the side or base to push parts between stations in a cramped layout.
Fine-adjust gauge stopper
Used as an end stop on a gauge or check station, where the adjustable range dials in the exact stop position and the bumper cushions each approach.
FAQ
Does MDJ25X30-30 include a magnet for switch sensing?
No. The code has no trailing S, so this SKU is without the magnet. The same cylinder with a magnet is ordered as MDJ25X30-30S. Magnetic-switch slots are machined around the body either way.
Where does this cylinder mount from, and what limits the stroke?
It fixes from six directions - front, back, left, right, top and bottom - so it can be placed wherever the fixture allows and units can sit side by side to save space. The short body cover cautions against an over-long stroke; confirm stroke-related dimensions and side-load limits from the datasheet before designing it in.
