CMK1 series gear motors are one of the leading products of our company. It adopts aluminum alloy shell with high strength, floating axial compensation structure, DU bearing structure with strong bearing capacity, with the pressure of 16MPa, the output volume of 4 to 25ml/r, and the rotary speed range of 600 to 3000r/min. It has characteristics of multiple specifications for output volume, simple structure, small volume, light weight and reliable operation. There are four kinds of connection of shaft extension, namely, flat keys, multiple keys, involute multiple keys and cone-axis screw thread. CMK1 series motors can rotate unidirectionally or bi-directionally. They can also carry safety valves when they rotate unidirectionally, and can be widely used in construction machinery, mining machinery, hoisting and transporting machinery, agricultural machinery and other medium and small-sized hydraulic systems.
