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.
