Bearings: Types and Uses

Posted - May 18, 2023

Bearings are mechanical components used to reduce friction and constrain motion between moving parts. There are several different kinds of bearings, each with unique properties that make them well suited for specific applications. Here’s a quick rundown of bearing types and their uses. 

Ball Bearings

A ball bearing is composed of a ring of steel balls contained by a rotating cage. Its purpose is to support rotating shafts and minimize friction between moving and stationary machine components. Ball bearings are engineered to allow both normal and axial loading and to tolerate high speed rotation. They are generally used for applications that involve relatively light loads and high speeds. 


Roller Bearings

Like ball bearings, roller bearings consist of rolling elements held between an inner ring and an outer ring. However, rather than point contact (where each ball only touches a very small part of the ring) they have line contact, which means more touching between the rolling elements and the rings. As a result, they offer higher shock and impact resistance than ball bearings, and are used for applications that require the support of heavier loads. There are several types of roller bearings, including:

  • Cylindrical roller bearings
  • Spherical roller bearings
  • Needle roller bearings
  • Tapered roller bearings 



Mounted Bearings

Mounted bearings are simply bearings (either ball or roller) that are housed in mounting components. There are a couple different types, including flange and pillow block bearings. Mounted bearings make installation and replacement easier and provide extra support and protection to bearing components.Mounted Bearings
