About the Airtac MDJ Adjustable Cylinder MDJ25X40-10
The AirTAC MDJ series is a compact multi-mount cylinder with a square body that can be fixed from six directions: front, back, left, right, top and bottom. Bodies can be mounted side by side to save space, with magnetic-switch slots machined around the body and high guide precision that needs no added lubricant. This MDJ25X40-10 is double acting with a 25 mm bore, a 40 mm stroke and an extra 10 mm of adjustable stroke, giving a theoretical push thrust of 245.4 N at 0.5 MPa. Cushioning is by bumper. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), from -20 to 70 C.
This is a genuine AirTAC part. The MD family is the standard multi-mount cylinder, while the MK family adds a no-rotating plate for jobs where the rod must not turn. This SKU is supplied without a magnet, exactly as listed. We are glad to 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
Choose the 25 mm bore when you need roughly 245.4 N of push thrust at 0.5 MPa (206.2 N on the pull side). MDJ is the adjustable-stroke, double-acting member of the standard MD family; pick MK instead if the rod must be prevented from rotating. The 40 mm base stroke sits within the 60 mm maximum for this bore in double acting, and the -10 suffix adds a further 10 mm of adjustment on top. Avoid over-long strokes, since the short cover limits how far the stroke can run, and confirm side-load capacity with us. Port thread is PT as standard (G available); this SKU has no magnet.
Applications
Adjustable clamp on assembly jigs
Clamping small machined parts on a drilling or riveting jig, where the fine 10 mm stroke tuning lets the pad seat on each part without crushing.
Stopper on pallet conveyors
Halting pallets at a manual station or robot pick point; the square body bolts from the top or side of the frame and units sit side by side in tight cells.
Part-present eject on pick-and-place
Pushing a small component off a nest into a pick pocket, with the adjustable stroke trimmed so the part lands square in the gripper zone.
FAQ
What does the -10 in MDJ25X40-10 mean?
MDJ is AirTAC's adjustable-stroke, double-acting multi-mount cylinder. The 25 is the bore in mm, the first 40 is the stroke in mm, and -10 means an extra 10 mm of stroke adjustment on top of the base stroke. This SKU has no magnet and a PT port thread.
Can I mount this cylinder from any direction?
Yes. The multi-mount body fixes from six directions: front, back, left, right, top and bottom, and cylinders can be mounted side by side to save space. For exact overall dimensions and side-load limits, confirm from the datasheet or ask us.
