Cam Backstop Clutch One Way Clutch MZ Series One Way Bearing for Machine
Production Introduction
Type MZ is a sealed, sprag type freewheel, bearing supported using two 60..ZZ series grease lubricated bearings. Units are delivered grease lubricated ready for installation. MZ units are intended as multipurpose, to be used in various applications.
In the long-wall coal mining face, the shearer uses the working mechanism to break the coal body from the coal body (coal crushing) and load it into the working face conveyor (coal loading). The shearer travels (pulls) at a set hauling speed, so that the coal crushing and charging process is carried out continuously. An important part of the shearer is the bearing.
The quality of bearings is directly related to production efficiency, so everyone must choose bearings with guaranteed quality.
The shearer is the main equipment of the fully mechanized mining equipment. The shearer is developed from the shearer. The shearer is a large and complex system integrating machinery, electricity and hydraulics. Bad working conditions. If it fails, it will lead to the interruption of the entire coal mining operation, resulting in huge economic losses.
