Roller Bearings

Roller bearings,known as rolling-element bearings,are similar to ball bearings in that they are designed to carry a load while minimizing friction , As opposed to ball bearings, roller bearings have barrel-shaped rolling elements instead of spherical balls. They are capable of supporting heavier loads than similarly sized ball bearings but cannot handle as high of speeds as ball bearings. 

Roller bearings contain an inner and outer ring that house the rollers and bearing cage. Also known as a retainer or separator, the cage maintains spacing between rollers and holds the bearing together. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing. These versatile bearings can contain single or multiple rows of rolling elements; multiple rows can significantly improve radial load capacity. Also, the use of different roller shapes can further reduce friction and support both radial and axial loads.While roller bearings can handle higher loads than conventional ball bearings, their applications are generally limited to low-speed operations.


Roller bearings are divided into several popular types according to their shapes and features: Spherical Roller Bearings, Cylindrical Roller Bearings, Tapered Roller Bearings, and Spherical Roller Thrust Bearings. They are widely used in the industrial and our daily life.
