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.

Product Overview of Roller Bearings

●Roller Bearings are used for bearing axial load. They are also called axial bearings.
●Similar to Roller Bearings, thrust bearings contain two seat rings, a group of rolling elements and a cage for retaining the rolling elements.

Product Features of Roller Bearings

Features of Roller Bearings:
●Roller Bearings can be considered as a kind of special thrust cylindrical roller bearings, whose length-to-width ratio is defined as the ratio of roller length to diameter, and obviously greater than 2.
●Roller Bearings can be a complete bearing unit with thrust washers and roller cage components, or a needle and cage integrated unit.
