The roll bearing of the rolling mill is very important and is the core component for the normal operation and normal rotation of the roll. The working environment of rolling mill bearings requires it to have large bearing capacity, strong impact resistance, and unstable working temperature, so it is necessary to choose suitable bearings to reduce the downtime of rolling mill failures.
A bearing arrangement, which is typically used to support a rotating shaft, generally requires two bearing supports. Depending on the requirements, such as stiffness or load directions, a bearing support consists of one or more (matched) bearings. Bearing arrangements for heavy loads. Bearing arrangements for greater rigidity and higher speeds.
Different specifications of the ball mill selection of pinion teeth and modulus are not the same. Mainly according to the speed of the mill and the bearing capacity of the gear itself. Regardless of the type of ball mill, the quality of the pinion is of great importance, which directly affects the operation and service life of the equipment.
The socalled bearing type value (kf) assumes the actual design of the bearing to be lubricated. This factor can have values between and 10 for kinematically simple ball bearings. For kinematically complex bearings (like axial cylindrical roller bearings with high sliding friction) the kf factor can reach values up to 90.
