SL-CM Coal mining machine hydraulic nuts

Coal machine hydraulic nuts are nuts used in hydraulic systems in coal mining equipment. Hydraulic nuts generally consist of two parts: a screw and a nut. They connect the two parts together by hydraulic pressure to achieve the function of tightening.

The locking of hydraulic nut of coal mining machine is different from ordinary nut, the locking of ordinary nut is to rely on turning the spanner to generate torque to lock, hydraulic nut in the locking project, is to rely on hydraulic pressure to act directly on the nut to generate ultra-high-pressure preload, even in the vibration of the working conditions, the parts will not loosen the connection.

The hydraulic nut is especially suitable for tightening the parts of coal mining equipment.
