Airtac MDD Multi-position Double Rod Cylinder MDD20X15S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD20X15S 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 MDD20X15S
The AirTAC MDD20X15S is a double-rod multi-mount cylinder: a compact square-body cylinder with a rod on both ends that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with other cylinders to save space. With a 20 mm bore and 15 mm stroke it delivers about 157.1 N of theoretical push force at 0.5 MPa on each side, and its cushion is a bumper that absorbs end-of-stroke impact. Magnetic-switch slots around the body take position sensors, and this SKU carries the built-in magnet (trailing S) for switch detection.
This is a genuine AirTAC part in the standard MD family, so rotation of the rod is not prevented; it is a double-acting double-rod cylinder, air-operated in both directions with output available from both rod ends. Operating pressure is 0.15-1.0 MPa (22-145 psi), the medium is air filtered to 40 um, and the working temperature is -20 to 70 C (0 to 150 C only with the optional high-temperature seal material). We confirm dimensions and 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.
How to choose
Choose the 20 mm bore when you need roughly 157.1 N theoretical push at 0.5 MPa; larger bores give more thrust, smaller bores less. This is the MDD double-rod variant of the standard MD family (rotation allowed); if the load must not turn, step to the MK no-rotating family instead. Acting is double with a rod on both ends, and the 15 mm stroke sits well inside the bore 20 table (up to 60 mm), keeping the covers short - avoid over-long strokes on a compact body. This SKU includes the magnet (S) for switch detection; non-magnet versions are available. Port thread is PT; a G thread version can be selected. Side-load capacity and exact dimensions per stroke come from the datasheet - ask us to confirm before you order.
Applications
Dual-side small-parts clamp
Mount the MDD20X15S in a compact fixture and clamp a small workpiece between the two rod ends of the double-rod body, fixing the cylinder from whichever of the 6 directions the jig allows.
Jig positioning with dual stops
Use the two rods of the double-rod cylinder to position a jig or workpiece from both sides in one compact envelope, with the 20 mm bore supplying about 157.1 N push at 0.5 MPa.
Inline gate or stopper on conveyors
Fix the cylinder to a machine frame from any of 6 directions and extend both rod ends to act as a gate or stopper for small parts on a conveyor line, with the bumper cushioning the stroke.
FAQ
What does the S in MDD20X15S mean, and what thrust does this bore give?
The trailing S means this cylinder is built with the magnet, so magnetic switches can detect piston position from the slots around the body; a code without S is the non-magnet version. The 20 mm bore gives about 157.1 N theoretical push force at 0.5 MPa on each rod side, with operating pressure 0.15-1.0 MPa (22-145 psi).
Can I mount this cylinder side by side, and are stroke-length options limited?
Yes. The square multi-mount body fixes from 6 directions (front, back, left, right, top and bottom), so cylinders can sit side by side to save space. Keep the stroke short relative to the compact body - this 15 mm stroke is well within the bore 20 table (up to 60 mm), but over-long strokes on short covers are best avoided. Exact per-stroke dimensions and side-load limits come from the datasheet; ask us to confirm.
