Airtac MDD Multi-position Double Rod Cylinder MDD20X15
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD20X15 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.

About the Airtac MDD Multi-position Double Rod Cylinder MDD20X15
The MDD20X15 is a double-rod multi-mount cylinder with a compact square body that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side with matching cylinders to save space. The 20 mm bore and 15 mm stroke give a theoretical push force of 157.1 N and 131.9 N on the rod-return side at 0.5 MPa, with a bumper cushioning the end of stroke. Magnetic-switch slots surround the body, and guide precision is high without any added lubrication.
This is a genuine AirTAC part in the MD standard family; the MK family is the no-rotating equivalent. As the SKU shows, no magnet is fitted on this model. Operating pressure is 0.15-1.0 MPa (22-145 psi) on air filtered to 40 um. Because overall dimensions change with stroke, we confirm exact figures 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
Pick the 20 mm bore for roughly 157.1 N of theoretical push at 0.5 MPa, with double rods giving a working rod at each end of the piston. This is the MD standard version where rotation is allowed; if your application needs rotation prevented, move to the MK no-rotating family. The 15 mm stroke fits the bore 20 table, which goes up to 60 mm, but the covers on this series are short - keep strokes modest rather than forcing an over-long stroke into the multi-mount format, and send side-load questions to us. This SKU has no magnet; choose an S suffix for the magnetic version. Port thread is PT as standard, with G offered as a suffix option.
Applications
Jig part alignment
Double rods nudge and align parts into position from either side of a fixture within a 15 mm stroke, with the body fixed through whichever mounting face the jig allows.
Small-parts ejection
Mounted top-down on a compact station, the 20 mm bore ejects or knocks finished small parts off a nest, with the bumper softening each short push.
Multi-point indexing fixture
Side-by-side MDD20X15 cylinders act as identical indexing pins or supports at several points on a machining or assembly fixture, each fixed independently from any of 6 directions.
FAQ
How does the MDD20X15 differ from the MK no-rotating version?
MDD is the standard MD family: double rods, double acting, with rod rotation allowed. The MK family adds a no-rotating plate, brass bushing and fixed rod so the rod or plate cannot turn. Both share the same 6-direction, side-by-side square body.
What should I check before specifying the 15 mm stroke?
The bore 20 table allows strokes up to 60 mm, but this series has short covers, so a very long stroke is better served by another series. Also confirm side-load limits and exact overall dimensions for your stroke from the datasheet before finalising the design.
