Where are slewing bearings used?Jul 17, 2024Slewing bearings, are extra-large rolling bearings consisting of an inner and outer annular seat ring and a rolling element, which are connected to the two parts of the structure of the machine or equipment that are rotating relative to each other to realise the relative slewing of the structure. Its field of application is very wide, covering almost all the need to withstand the combined load (including axial force, radial force and tilting moment) in the machinery and equipment.

What bearings are used in rolling mills?Jul 04, 2024The mill uses a variety of types of bearings, the specific selection needs to be based on the type of mill, working conditions and performance requirements and other factors for comprehensive consideration. In the selection of bearings, should give full consideration to its bearing capacity, limiting speed, precision requirements and lubrication and other factors, in order to ensure the stable operation of the mill and efficient production.
