The type and selection of rolling mill bearings depends on many factors, including bearing load, working speed, working environment and bearing size.

Thin section bearings, Tapered roller bearings, Cylindrical roller bearings, Slewing bearings, Ball bearings(Spindle Bearings), Cross roller bearings, Thrust bearings, Spherical bearings, Rollers(Rolling element)

When purchasing bearings, we usually don't know how to choose, and worry about buying fake products; worry about substandard quality, or not suitable for use after buying; worry about the lack of guarantee after sale. Before purchasing bearings, the following aspects need to be confirmed

Selection of raw materials: raw materials include 42CrMoT, 42CrMoZ, 50MnT, 50MnZ T: Indicates that the material should be quenched and tempered. Z: Indicates that the material should be normalized

Inspection items: Inner diameter, Outer diameter, Width, Radial clearance, Axial and radial runout (allowed to be replaced by detecting the difference in wall thickness of the two pieces and the difference in parallelism of the grooves), Contact angle, Starting friction torque, Dynamic friction torque and volatility.

The thin section ball bearing include the opened series and sealed series. Where there is no any severe pollution, the opened bearings should be preferred; Where the cleaning and well lubrication are required, the sealed bearings should be preferred.
