The fundamental design of cylindrical roller bearing consists of cylindrical rollers in linear contact with the raceways. The line contact of a roller bearing is used in place of the point contact of a ball bearing when the maximum load carrying capacity in a given space is needed. The cage guides and positions the compared short rollers in a cylindrical roller bearing. This bearing are suitable for high speed rotation due to the low friction between the ring ribs and rollers.
Cylindrical Roller Bearing
Following are the Advantages of Cylindrical Roller Bearing
- Due to line contact between rollers and races, the radial load carrying capacity of the cylindrical roller bearing is very high compared to ball bearing.
- Compared to ball bearings, cylindrical roller bearings are more rigid.
- Cylindrical Roller Bearing are easy to install, slim and save space and weight.
- In high speed applications, there is minimal frictional loss and a low coefficient of friction. Cylindrical Roller Bearing faster speeds than other types of roller bearing.
- Cylindrical Roller Bearing comes in several sizes and material, and they have straight outside and inside diameters.
Following are the Disadvantages of Cylindrical Roller Bearing
- Cylindrical Roller Bearing cannot take thrust load.
- Cylindrical Roller Bearing is not self aligning.
- Cylindrical Roller Bearing cannot tolerate misalignment. Precise alignment between the shaft's axis and the housing's bore is required.
- Cylindrical Roller Bearing generates more noise.
