The AirTAC Airtac MD Multi-Position Clamping Cylinder MD20X30S is a genuine MD multi-mount cylinder (double acting), 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 MD20X30S is a double acting multi-mount cylinder from AirTAC with a 20 mm bore and 30 mm stroke. The square body fixes from six directions, so cylinders mount side by side to save space, and magnetic-switch slots sit around the body for position sensing. At 0.5 MPa the bore gives a theoretical push force of about 157.1 N, cushioned by an elastic bumper for light-duty clamping and positioning.
This is a genuine AirTAC part, and the SKU includes the built-in magnet shown by the S suffix. It comes from the standard MD family - choose the MK family instead where the rod must not rotate. Operating range, port size and exact per-stroke dimensions can be confirmed 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.
A 20 mm bore gives a theoretical push thrust of 157.1 N at 0.5 MPa, the figure to size light clamping or gating against. MD means rod rotation is allowed, MK prevents it. Acting type is your call: double (this model), single push (MSD/MSK), single pull (MTD/MTK), double rod (MDD/MKD) or adjustable stroke (MDJ/MKJ). Strokes for this bore run up to 60 mm, though the short-cover design means very long strokes should be avoided. This SKU carries the S magnet and PT thread; G is available.
Extend and retract a locating pin in a drill or weld jig; six-way fixing lets the body sit wherever the jig frame allows.
Drive a light pneumatic slide that moves small parts a short 30 mm between nest and outlet, with units mounted side by side on one rail.
Push small finished parts out of a nest or chute with a short vertical stroke, using the compact body where full-size cylinders will not fit.
It means this SKU includes the built-in magnet, so the cylinder can be paired with magnetic switches seated in the slots around the body. Order the code without the S if you do not need position sensing; the S suffix is a choice, not a fixed feature of the family.
The bore 20 table runs up to 60 mm, but the short-cover design means an over-long stroke should be avoided. This 30 mm stroke is a comfortable fit; confirm any longer option or unusual mounting with us and the datasheet before ordering.
