Airtac MDD Multi-position Double Rod Cylinder MDD6X20
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD6X20 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 MDD6X20
MDD6X20 is a double-rod, double-acting AirTAC multi-mount cylinder with a compact square body that can be fixed from 6 directions - front, back, left, right, top and bottom - and mounted side by side to save space. The 6 mm bore and 20 mm stroke suit light-duty clamping and positioning in tight fixtures, with an operating pressure of 0.15-1.0 MPa (22-145 psi) and double-acting speed of 30-500 mm/s. Cushioning is a bumper. For this bore the facts-sheet double-acting figures are 14.1 N push and 10.6 N pull at 0.5 MPa; because the MDD carries a rod on both sides, confirm the per-side thrust from the datasheet before sizing.
This is a genuine AirTAC part in the MD family, the standard multi-mount range (the MK family is the no-rotating version, with an anti-rotation plate, brass bushing and fixed rod). Magnetic-switch slots surround the body and the design runs without added lubrication. This SKU is listed without a magnet (no S in the code). We confirm dimensions 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
Choose the 6 mm bore where only light force is needed: at 0.5 MPa the facts sheet lists 14.1 N push and 10.6 N pull for double acting. Stay in the MD family when rod rotation is acceptable, or step up to MK when it must be prevented. Acting choices are double acting (MD/MDD/MDJ), single push (MSD), single pull (MTD) and double rod (MDD). This 20 mm stroke sits within the 35 mm maximum for bore 6 double-acting cylinders, but note the short covers - avoid an over-long stroke on a compact body and check longer travel with us. This version has no magnet; add S to the code if you need switch detection, and pick PT (default) or G thread; side-load limits come from the datasheet - ask us.
Applications
Small-parts clamp
A push-pull clamp on an electronics fixture: the double rod gives a clamping face on each side of the 6 mm body, and 6-way fixing lets the cylinder bolt straight onto the jig plate.
Jig positioning
Nudging and locating small housings into a drill or press jig: the compact body mounts side by side where a tie-rod cylinder will not fit.
Pick-and-place shuttle
Short slide-and-return moves of tiny components between two nest points, where the 20 mm stroke and low-profile multi-mount body fit inside the machine envelope.
FAQ
Does MDD6X20 include a magnet for position switches?
No. This code has no trailing S, so it is supplied without a magnet. If you need reed or Hall-effect switch detection in the body slots, order the S version of the same bore and stroke instead.
Where can I find the exact dimensions and side-load limit for this cylinder?
Overall dimensions change with the stroke and the double-rod configuration, and the allowable side-load is not a fixed published number here, so both should be confirmed from the datasheet. We will provide the MDD6X20 datasheet and help with sizing on request.
