What Are Cylindrical Roller Bearings ?

Bearings are an essential part of industrial machinery. A bearing's goal is to ensure motion is regulated in a moving part and help reduce friction. 


The cylindrical roller bearings have a high radial load capacity and are suitable for high speeds. They are in linear contact with the raceways. They are designed to be reliable and a good fit for the environment.

The bearing is highly versatile and can be used for many applications. There are several different types of cylindrical roller bearings on the market.


They vary according to the number of rows of rollers (usually one, two, or four) and if there's a cage or not. No cage allows for the bearing to have more rows, which helps support even heavier radial loads.cylindrical roller bearings can support significant radial loads (even very significant ones).


Advantages: Long bearing life, support significant radial loads, robust


Disadvantages: Cannot tolerate high axial loads.


Cylindrical roller bearings can take some axial load in one direction when the inner or outer rings have two ribs.


Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.


Why choose a cylindrical roller bearing over a radial ball bearing?


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.
