The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD20X10S is a genuine MD multi-mount cylinder (double rod), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact.
The MDD20X10S is a double-rod multi-mount cylinder whose compact square body fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side with other cylinders to save space. The 20 mm bore with a 10 mm stroke gives a theoretical push force of 157.1 N and 131.9 N on the rod-return side at 0.5 MPa, with a bumper cushion at each end. Magnetic-switch slots run around the body, and the guide precision is high with no added lubricant needed.
This is a genuine AirTAC part from the MD standard family (the MK family is the no-rotating equivalent). The trailing S in the code means this unit carries a magnet for position sensing; the non-magnetic version is MDD20X10. Operating pressure is 0.15-1.0 MPa (22-145 psi) on air filtered to 40 um. Dimensions are per stroke, so we confirm exact 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.
The 20 mm bore delivers about 157.1 N theoretical push at 0.5 MPa with rods on both sides of the piston for balanced guiding. This is MD standard, where the rod is allowed to rotate; choose the MK no-rotating family if the load must not turn. The double-rod acting means a working rod at each end, and the 10 mm stroke is comfortably within the bore 20 table (up to 60 mm) - short covers favour short strokes, so avoid stretching an over-long stroke into this series and ask us about side-load figures instead. The trailing S gives you the magnet; drop it for the plain version. Thread is PT by default, with G available as a suffix.
The magnet lets a switch confirm rod position on both ends of the stroke, so the 20 mm double-rod unit can shift small parts a short 10 mm between stations in a side-by-side bank of cylinders.
Rods on both ends let one compact body clamp a part from two directions in a fixture, with the square housing bolted down through whichever of its 6 mounting faces suits the jig.
Use the 10 mm stroke to raise or retract a small stopper or gate on a conveyor, with switch feedback from the magnet confirming the stopper is clear before the next part passes.
The trailing S means this cylinder is built with a magnet in the piston, so magnetic switches can be seated in the slots around the body to signal position. The same cylinder without the S (MDD20X10) has no magnet.
No - the MDD series is the standard MD family and allows rod rotation. For applications that need the rod or plate held against turning, select the MK no-rotating family instead. Side-load limits and exact dimensions should be confirmed from the datasheet.
