The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD20X20S is a genuine MK 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. As an MK unit a fixed rod stops the piston rod rotating.
The MKD20X20S is an AirTAC MK-series multi-mount cylinder with a square body that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side to save space. It is the MKD double-rod variant, so the rod is available at both ends of the body, and being an MK cylinder it is no-rotating: a plate and fixed rod stop the rod turning so your tooling stays oriented. The 20 mm bore gives a theoretical 157.1 N push and 131.9 N pull at 0.5 MPa for small-part clamping and positioning, with a bumper cushion and operation on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
This is a genuine AirTAC part sold by an authorized distributor. Against the standard MD family, the MK family prevents rod rotation - choose MD when rotation is acceptable. The trailing S here means the cylinder comes WITH a magnet, so switch sensing on the body slots is ready to use. Body dimensions depend on stroke and mounting face, so confirm the 20 mm stroke envelope from the datasheet, and ask us for sizing or compatibility help 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.
Pick the 20 mm bore when your job needs about 157.1 N of push force (131.9 N on the pull side) at 0.5 MPa. The MKD construction adds a double rod to the no-rotating MK body, giving actuation from either end without rod twist - well suited to symmetric fixtures. This SKU is the magnet-fitted version (trailing S) with a 20 mm stroke and M5x0.8 ports with PT threads; a G-thread option exists on other SKUs if your piping needs it. Because these multi-mount bodies have short covers, avoid over-long strokes and confirm any longer variant with us first. Side-load ratings are not listed here - route those questions to us and the datasheet.
The magnet allows end-of-stroke sensing while the no-rotating double rod keeps a gripper plate square, so the cylinder presents small parts without rotation in tight cells.
With 157.1 N of push at 0.5 MPa from the 20 mm bore, this compact cylinder clamps small workpieces on fixtures where cylinders must sit side by side to save space.
Mounted top or bottom on the line frame, the magnet-fitted rod kicks rejects off a conveyor with a sensed stroke, and the fixed-rod design keeps the pusher blade aligned.
The trailing S means this SKU is supplied WITH a magnet for magnetic-switch sensing. MKD = MK-family double rod (no-rotating, rod on both sides), 20 = 20 mm bore, X20 = 20 mm stroke. It is double acting at 0.15-1.0 MPa (22-145 psi) with M5x0.8 PT-thread ports, and delivers a theoretical 157.1 N push at 0.5 MPa.
Yes - the square body fixes from 6 directions (front, back, left, right, top and bottom) and units mount side by side to save space, with switch slots around the body. Because the covers are short, keep strokes modest; an over-long stroke on a short-cover body is best avoided, so confirm alternatives with us. Side-load figures come from the datasheet, not from this page.
