Coal mining machine hydraulic nut is the nut used in the hydraulic system in coal mining equipment. Hydraulic nut generally consists of two parts, the screw and the nut, through the hydraulic pressure to connect the two parts together, to achieve the role of tightening. In the locking project, it is relying on hydraulic pressure to act directly on the nut to produce ultra-high pressure preload, even in the vibration of the working conditions, the parts will not loosen the connection.
