What is the classification of bearings according to the shape of rolling elements?

Rolling bearings are mainly divided into: ball bearings and roller bearings. Among them, ball bearings are divided into: deep groove ball bearings, angular contact bearings and radial thrust ball bearings. Roller bearings are divided into: cylindrical roller bearings, needle bearings, cone roller bearings and self-aligning roller bearings.

What is the classification of bearings according to load direction?

Bearing are divided into: radial bearings and thrust bearings according to the load direction. Among them, radial bearings are divided into: radial thrust ball bearings and radial roller bearings. Thrust bearings are divided into: thrust ball bearings and thrust roller bearings.

Is lubrication required for thrust bearings?

The lubrication methods of bearings are divided into grease lubrication and oil lubrication. In order to ensure the proper functioning of bearings, it is necessary to choose a lubrication method that is suitable for the conditions and purpose of use. If only lubrication is considered, the lubricity of oil lubrication has advantage.

Product Overview of Ball Bearings

●Ball Bearings are specialized bearings used to withstand axial forces, i.e. bearings with forces parallel to the axis.
●Ball Bearings include types such as "thrust ball bearings" and "thrust needle roller bearings".

Product Features of Ball Bearings

Features of Ball Bearings:
●Ball Bearings can be considered as a split type bearing, where the axis ring and seat ring can be split from the components of the cage and ball.
●Ball Bearings cannot limit the radial displacement of the axis, and one-way thrust ball bearings can limit the axial displacement of the axis and housing in one direction.
