The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD20X5 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 MDD20X5 is an AirTAC MD series double rod multi-mount cylinder: a compact square-body pneumatic cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with other units to save space. Its 20 mm bore in a double rod configuration gives a 157.1 N full-bore push figure at 0.5 MPa on the rod side (131.9 N); because rods project from both ends, confirm the exact effective thrust for your mounting from the datasheet. Cushioning is a bumper, and the very short 5 mm stroke suits compact, quick-retraction jobs.
This is a genuine AirTAC part in the standard MD family (rotation of the rod is not prevented - that is the MK family). This SKU carries no magnet and has PT threads as standard. Air filtered to 40 um is the medium, with an operating pressure of 0.15-1.0 MPa (22-145 psi) and a temperature range of -20 to 70 C. We confirm dimensions, weights 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.
Bore sets the thrust: a 20 mm double rod bore delivers up to 157.1 N (push) at 0.5 MPa. Choose MD if rod rotation is acceptable, or MK if the rod must not turn. This is the double rod variant - rods on both ends. The 5 mm stroke sits well inside the bore-20 table (up to 60 mm); the short body keeps the footprint tight, and an over-long stroke should be avoided where the cover projection gets in the way. No magnet is fitted on this SKU (choose an S suffix if you need one), and the thread is PT - G is available as an alternative.
Dual opposing rods press a workpiece from both sides in a tight fixture, with the 6-way body mounting wherever the jig frame allows and the bumper easing each clamp cycle.
Side-by-side mounting of several 20 mm bore bodies lets one manifold block position multiple short-stroke pins in an assembly jig without extra mounting hardware.
A 5 mm push kicks finished small parts out of a nesting station; the double rod keeps the ejector guided and the body bolts from the top or side of the nest plate.
The MDD20X5 has piston rods projecting from both ends of the cylinder. It stays a double acting MD family unit with 0.15-1.0 MPa (22-145 psi) operating pressure, but because both faces work against the rod area, effective thrust is lower than the full-bore push figure - confirm the exact value for your setup from the datasheet.
Yes. The multi-mount square body can be fixed from 6 directions - front, back, left, right, top and bottom - and several units can be mounted side by side to save space. Overall dimensions vary with stroke, so take mounting dimensions from the datasheet.
