Airtac MDD Multi-position Double Rod Cylinder MDD6X25S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD6X25S 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 MDD6X25S
The MDD6X25S 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. The trailing S means this SKU carries a magnet for position detection in the body's switch slots. 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. The S suffix adds the magnet, so reed or solid-state switches can read position in the slots around the body.
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.
Positioned stopper on an assembly station
The magnet lets sensors confirm the stopper is fully out or retracted before the station cycles, while the 25 mm stroke raises and lowers a small pause blade on a parts feeder.
Two-sided part ejection in a compact indexer
Both rod ends push together to advance or eject a micro-part from a pallet nest on a rotary indexing table, with the magnet signalling end-of-stroke between indexes.
FAQ
What does the S in MDD6X25S mean?
The trailing S means this cylinder is supplied with a magnet in the piston, so magnetic switches can detect rod position in the slots around the body. The same cylinder without the S (MDD6X25) has no magnet. The magnet is an option, not a standard feature.
How does the 6-way mounting work on this cylinder?
The square body can be fixed from six directions - front, back, left, right, top and bottom - and several cylinders can sit side by side to save space. Stroke-length dimensions and allowable side load are not stated here; confirm them from the datasheet before finalising the fixture design.
