Airtac MKD Multi-position Clamping Cylinder MKD6X15
The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD6X15 is a genuine MK multi-mount cylinder (double rod), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 14.1 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.

About the Airtac MKD Multi-position Clamping Cylinder MKD6X15
The MKD6X15 is a genuine AirTAC MK-series multi-mount cylinder, a compact square-body unit that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side with other units to save space. This 6 mm bore, 15 mm stroke double-rod double-acting version drives from both rod ends; with a rod through each side, theoretical thrust is about 10.6 N per side at 0.5 MPa, cushioned by a bumper. Operating pressure is 0.2-1.0 MPa (28-145 psi) on this bore.
This SKU has no magnet (no trailing S), so position sensing is not built in - order an S variant if you need it. The MK family is the no-rotating multi-mount line: a plate, brass bushing and fixed rod stop the rod from turning, unlike the standard MD family. Porting is M5x0.8 with PT thread. We confirm exact dimensions, weight and side-load limits from the AirTAC 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.
How to choose
Pick the 6 mm bore for light, accurate thrust - about 10.6 N per side at 0.5 MPa on this double-rod design. The 15 mm stroke sits well inside the 35 mm limit for a 6 mm bore while giving a little more reach than the shortest bodies. MK prevents rod rotation; MD allows it, so choose by whether your tooling must stay oriented. Acting is double with a rod at both ends, letting you work from either side of the body. This unit carries no magnet; add the S option for switch sensing. Port thread is PT, with G available.
A short cover means the bore tolerates only modest side loads and only moderate strokes - 15 mm is a sensible choice here, but check any sideways loading with us against the datasheet before you commit.
Applications
Jig positioning pin
Fix the body to the jig plate from underneath and extend the rod to raise a locating pin into a drilled hole. The no-rotating plate keeps the pin's orientation true on every cycle.
Vertical ejector under a small mold or nest
Mount the cylinder top-down beneath a nest and use the double rod to eject lightweight parts upward after forming. The 15 mm stroke clears shallow pockets, and the bumper cushions the return.
Fine-adjust stop on a test station
Bolt units side by side along the fixture edge and set stop positions per variant. The non-rotating rod keeps the stop face aligned, and side-by-side bodies keep the layout compact.
FAQ
Why choose MKD6X15 over the standard MD family at the same bore and stroke?
MKD is the no-rotating double-rod variant: a plate, brass bushing and fixed rod stop the piston rod from turning, which matters when a pin, stopper or pad must stay oriented. The MD family is the standard type where the rod may rotate. Both fix from 6 directions and mount side by side; this 15 mm stroke is well within the 35 mm limit for a 6 mm bore.
What pressure, porting and cushioning does the MKD6X15 use?
Operating pressure on this 6 mm bore MK double-acting cylinder is 0.2-1.0 MPa (28-145 psi), with proof pressure of 1.5 MPa (215 psi). The port is M5x0.8 with PT thread (G is offered as an option), the medium is air filtered to 40 um, and cushioning is a bumper, not an air cushion. Temperature range is -20 to 70 C, or up to 150 C only with the optional high-temperature seal material.
