The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD20X30 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 AirTAC MK series is a compact square-body multi-mount cylinder that fixes from six directions - front, back, left, right, top and bottom - and can be mounted side by side to save space, with magnetic-switch slots machined around the body. The MKD20X30 is the double-rod, double-acting version: rods extend from both ends, so a tooling plate or paired loads can be driven from either side across a 30 mm stroke. At 0.5 MPa a 20 mm bore delivers 157.1 N on a plain push side and 131.9 N on the rod side; with rods on both ends, confirm per-side output from the datasheet. Cushioning is a bumper.
This is a genuine AirTAC part distributed for the US market. MK is the no-rotating family: a fixed rod and no-rotating plate stop the piston rod from turning, unlike the standard MD family. As the SKU shows, the MKD20X30 carries no magnet; choose the S suffix if you need magnetic switch sensing. Medium is air filtered to 40 um, proof pressure is 1.5 MPa, and temperature range is -20 to 70 C (0 to 150 C only with the optional high-temperature seal material). Overall dimensions and side-load limits are per the datasheet - we confirm sizing 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.
Choose the 20 mm bore for roughly 157 N push (131.9 N rod side) at 0.5 MPa, or step up to 25 or 32 mm for more force. MKD is the double-rod no-rotating choice when rotation must be prevented and you need output at both ends; the MD family allows rotation, while MK, MKD, MSK, MTK and MKJ prevent it. Double acting powers the stroke both ways, single acting push (MSK) or pull (MTK) returns by spring, and MKJ adds a 10, 20 or 30 mm adjustable range. The 30 mm stroke sits comfortably inside the 60 mm limit for bore 20 - the short covers of a compact body caution against an over-long stroke. This SKU has no magnet; add S for one. Port thread is PT; G is available.
Slide small parts sideways between stations with rods driving a carrier at each end; the no-rotating rod keeps the carrier oriented without guides.
Close two clamp jaws onto a workpiece from opposite sides of a fixture; the double rod moves both jaws from one compact, side-by-side mounted body.
Eject finished parts off a small assembly nest at end of cycle, pushing squarely because the rod is prevented from rotating under the load.
Both ends of an MKD carry a rod, so each side works on the rod-side (annular) area rather than the full piston area. For this 20 mm bore the facts sheet lists 157.1 N push and 131.9 N pull at 0.5 MPa; confirm the exact per-side output for the MKD from the datasheet before sizing.
The square body fixes from six directions - front, back, left, right, top and bottom - and cylinders can be mounted side by side to save space. Slots around the body take magnetic switches, but this MKD20X30 SKU is built without a magnet, so select the S suffix if you need sensing.
