Product Description
What are Cylindrical Roller Bearings and How are They Used?
Cylindrical roller bearings are similar to radial ball bearings in that they are designed to carry a radial load while minimizing friction. Cylindrical roller and radial ball bearings can also handle a small amount of axial loads depending on the application and internal design of the bearings.
In general, roller bearings offer higher load capacities than ball bearings of the same size. The other significant difference between the two bearings is their contact area. For ball bearings, the contact area is a single point where the roller bearings hit a much larger area.
