Airtac MKD Multi-position Clamping Cylinder MKD6X5
The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD6X5 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 MKD6X5
The MKD6X5 is a compact no-rotating multi-mount cylinder from AirTAC's MK family: a square-body, double-acting unit with a rod on both ends that can be fixed from six directions - front, back, left, right, top and bottom - so several cylinders mount side by side to save space. With a 6 mm bore and a 5 mm stroke it suits very short, precise movements in tight fixtures. Because both ends carry a rod, each side delivers the rod-side theoretical thrust of about 10.6 N at 0.5 MPa. Cushioning is a bumper.
This is a genuine AirTAC part. In the MK family a fixed rod, bushing and no-rotating plate typically stop the piston rod from turning, while the MD family is the standard version where rod rotation is not prevented. This SKU carries no position magnet (no S suffix). Overall dimensions are per stroke, so confirm them and any sizing detail 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.
How to choose
Bore sets the thrust: this 6 mm double rod gives a theoretical thrust of about 10.6 N on each rod side at 0.5 MPa, with operating pressure of 0.2-1.0 MPa (28-145 psi) and double-acting speed of 30-500 mm/s. MKD means a double rod with rotation prevented; choose MD if some rod rotation is acceptable, or MK for a single-ended no-rotating rod. The 5 mm stroke sits well inside the 35 mm maximum for bore 6, and the short covers reward keeping the stroke short rather than specifying an over-long one. No S in the code means no magnet is fitted; PT thread is default with G available. Side-load limits come from the datasheet - check with us.
Applications
Two-sided small-parts clamping
The double rod extends a pin on both ends at once, letting one 6 mm cylinder grip or locate a small part from both sides of a micro fixture.
Square stopper blade
The no-rotating rod keeps a stopper or gate plate facing square to the part flow, so the 5 mm stroke ejects or blocks repeatably without the blade twisting.
Side-by-side actuator banks
Six-direction fixing and a square body let several MKD6X5 cylinders be bolted next to each other for multi-point jig or test-station actuation in a narrow footprint.
FAQ
What does the D in MKD6X5 mean?
MKD is the double-rod version of the MK no-rotating multi-mount cylinder: a piston rod extends from both covers. Each side therefore works on the rod-side area, giving a theoretical thrust of about 10.6 N per side at 0.5 MPa. The decode is MKD + bore (6) + X + stroke (5), PT thread as standard with G available.
How does six-direction mounting help in a tight fixture?
The square body can be fixed from the front, back, left, right, top or bottom, and magnetic-switch slots run around it, so you can orient the cylinder to suit the machine layout and place several units side by side. Overall dimensions change with stroke, so confirm them from the datasheet before designing the mounting.
