The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD20X15S 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 MKD20X15S is an AirTAC MK-series multi-mount cylinder with a compact square body you can fix from 6 directions - front, back, left, right, top and bottom - and mount side by side to save space. This is the double-rod (MKD) variant, so the rod is available on both sides of the body, and it is no-rotating: a plate and fixed rod stop the rod turning, so the load stays oriented. With a 20 mm bore it gives a theoretical 157.1 N push and 131.9 N pull at 0.5 MPa, suited to clamping and positioning on small fixtures, and it cushions with a bumper while running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
This is a genuine AirTAC part sold through an authorized distributor. The MK family differs from the standard MD family by preventing rod rotation; the MD line is the equivalent standard cylinder where rotation is acceptable. The trailing S on this SKU means it comes WITH a magnet for proximity-switch sensing; non-S SKUs are supplied without. The short 15 mm stroke keeps the body compact - confirm exact dimensions and fit from the datasheet, and ask us for sizing help any time.

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.
Choose the 20 mm bore when you need around 157.1 N of push force (131.9 N on the pull side) at 0.5 MPa. MKD gives you the no-rotating MK body with a double rod, so the rod is present on both sides - useful when you actuate or locate from either end. This SKU carries a 15 mm stroke and a built-in magnet (S). Air ports are M5x0.8 with PT threads on this bore size; G threads are available on other SKUs. Keep strokes short on compact multi-mount bodies - an over-long stroke on a short cover can load the rod poorly, so confirm any longer stroke with us. Side-load limits are not quoted here; route those questions to us and the datasheet.
The no-rotating rod and double-rod body hold parts squarely from either side, making the MKD20X15S a neat clamp on compact jigs where side-by-side cylinders save fixture width.
With the rod kept from turning, a locating platen or stop stays square to the fixture, so the 20 mm bore positions workpieces repeatably in assembly jigs.
Magnet-equipped for switch sensing, this short-stroke cylinder indexes and stops small parts on fixtures and pallets where mounting space is tight.
The MKD prefix means double rod on the no-rotating MK body: the rod extends on both sides of the cylinder, and a plate with a fixed rod prevents rotation. At 20 mm bore you get a theoretical 157.1 N push and 131.9 N pull at 0.5 MPa. The trailing S means this SKU includes a magnet for switch detection; SKUs without S are supplied without a magnet.
The square body lets you fix the cylinder from 6 directions - front, back, left, right, top and bottom - and mount units side by side to save space, with magnetic-switch slots around the body. Allowable side load is not a published figure here, and overall dimensions vary with stroke, so confirm both from the datasheet or ask us before designing the mount.
