Airtac MDD Multi-position Double Rod Cylinder MDD20X60S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD20X60S 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 MDD20X60S
The AirTAC MD multi-mount family is a compact square-body cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side with neighbouring units to save space, with magnetic-switch slots around the body and high guide precision. This MDD20X60S is the double-rod, double-acting variant: the rod leaves both covers, so the 20 mm bore can push and pull from either end over a 60 mm stroke, cushioned by a TPU bumper. Because both faces are rod sides, the theoretical rod-side thrust is about 131.9 N at 0.5 MPa, over an operating pressure of 0.15-1.0 MPa (22-145 psi) and speeds of 30-500 mm/s.
This is a genuine AirTAC part from the standard MD family - double rod, not the no-rotating MK type. The trailing S in the code means the magnet is fitted. It runs on air filtered to 40 um between -20 and 70 C, with an M5x0.8 port and PT thread. We confirm dimensions, weight 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
Bore 20 gives a theoretical rod-side thrust of about 131.9 N at 0.5 MPa; choose a larger bore if the load needs more force. Stay in the MD family when rod rotation is acceptable; pick MK when rotation must be prevented. This MDD double-rod, double-acting variant offers a working face at each cover and air power in both directions at 30-500 mm/s. Note that 60 mm is the top of the bore-20 stroke table - the short covers keep the body compact, but an over-long stroke adds length for no benefit, so choose the shortest stroke that covers the job. The trailing S orders the magnet; drop the S for no magnet. Thread here is PT, with G available as the alternative. Route any side-load requirement to us and confirm from the datasheet.
Applications
Pick-and-place transfer
Fix the cylinder to a small gantry through any mounting face and let the rod carry a suction-cupped part sideways across a 60 mm transfer step, with the bumper easing the end of travel.
Rotary-index assist
Mount units side by side on an indexing fixture so one double rod locks the dial while the opposite rod end releases it, giving a compact push-pull pair in one body.
Gate and stopper duty
Bolt the body to a conveyor bracket from the top or side and use a rod end to raise and lower a stopper blade, diverting or holding parts as they pass.
FAQ
How much stroke can a bore 20 multi-mount cylinder take?
Bore 20 double-acting units are listed up to 60 mm, so this MDD20X60S sits right at that maximum. The short covers keep the body compact, but an over-long stroke adds length for no benefit, so choose the shortest stroke that covers the job and confirm the overall length from the datasheet.
Can I put a side load on the rod?
The body offers high guide precision and runs without added lubricant, but an allowable side-load figure is not published here, so route any off-axis or side-load requirement to us and confirm it from the datasheet before sizing the application.
