Airtac MDD Multi-position Double Rod Cylinder MDD6X25
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD6X25 is a genuine MD multi-mount cylinder (double rod), 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.

About the Airtac MDD Multi-position Double Rod Cylinder MDD6X25
The MDD6X25 is a compact square-body multi-mount cylinder that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side to save space. This double rod version in a 6 mm bore with 25 mm stroke extends a rod from both ends, so both faces can do work, such as clamping between two points or pushing in two directions from one cylinder. It is double acting, runs at 0.15-1.0 MPa (22-145 psi) and delivers a theoretical push force of about 14.1 N at 0.5 MPa on each rod side. Cushioning is a bumper, and magnetic-switch slots run around the body.
This is a genuine AirTAC part. The MD family is the standard multi-mount cylinder; the MK family is the no-rotating version with a plate that stops the rod turning, so choose MK if rotation must be prevented. This SKU has no magnet (no trailing S). Overall dimensions and rod details vary by stroke - we confirm them 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
Bore sets the force: this 6 mm bore gives about 14.1 N theoretical push at 0.5 MPa (double acting), so size up to bore 10, 16 or beyond if you need more. The double rod (MDD) variant gives you working force on both ends of the piston - useful for symmetric clamping or dual pushes. Strokes for double acting bore 6 run up to 35 mm, and this 25 mm stroke sits comfortably inside that; the compact body should not be pushed to an over-long stroke. No magnet on this SKU; add the S suffix if you need switch detection.
If rod rotation must be prevented, pick the MK family instead. Ports are M5x0.8 with PT thread on this SKU; G thread is available as a suffix. Allowable side load is a datasheet value - confirm it with us before applying side loads.
Applications
Small-parts clamping between fixtures
The double rod clamps a small plastic or electronics part between the two rod ends in a compact test or assembly fixture, with 6-way fixing letting the cylinder bolt flush inside a tight jig.
Miniature conveyor gate/stopper
Mounted side by side along a narrow conveyor edge, the 25 mm stroke lifts or drops a small stopper blade to divert or pause tiny parts flowing down the line.
Dual-action ejector in a small die or mould
Both rod ends push simultaneously to eject or index a finished micro-part from a compact workholder, saving the space a second cylinder would occupy.
FAQ
What is the difference between the MDD6X25 and the single-rod MD6X25?
The MDD is the double rod variant: a rod extends from both ends of the piston, so both sides deliver the same theoretical push force, about 14.1 N at 0.5 MPa for the 6 mm bore. The standard MD has a rod on one side only, where the pull side force is lower. Both are double acting at 0.15-1.0 MPa (22-145 psi).
Can I detect the piston position on this cylinder, and can it take side loads?
This SKU has no magnet (no trailing S), so position detection is not built in - choose the MDD6X25S for the magnet and switch slots. Multi-mount bodies fix from 6 directions and mount side by side, but allowable side load is not stated here; confirm it from the datasheet before applying side loads.
