MMB Bearings is one of the largest stocking distributors and suppliers of high-quality bearings. We have the widest variety of quality precision bearings for every possible application and industry, including miniature ball bearings, roller bearings, linear bearings, and much more. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts. In simpler terms, if something moves, turns, or twists, it likely has a bearing in it. Bearings are found in moving components, equipment, and machines in virtually every industry. Not only do bearings prevent friction, they also reduce the heat generation, energy consumption, and wear and tear of parts. In general, they permit a specific type of motion in a system.

Ball Bearings

A ball bearing is a mechanical assembly that uses spherical bearings or balls to facilitate rolling motion between circular inner and outer races. Their main functions are to position moving parts, reduce friction, and support and carry loads. Ball bearings offer a point contact between the balls and raceways. While they can rotate at extremely high speeds, they cannot support substantial loads. The following are some key considerations and benefits of ball or spherical bearings.


  • Provide low friction rotation
  • Optimal for high speed applications
  • Good wear resistance
  • Essential to ultra-precision applications
  • Have limited load-carrying capacity
  • Support axial and radial loads with specific configurations
  • Standardized to permit easy replacement and interchangeability
  • Available in different roller shapes and in single– or multiple–row configurations

The size and width of ball bearings vary according to their use and application. For example, miniature ball bearings are used for high-precision instrument applications in the medical industry. Also, the material used for ball bearings will vary depending on application as well. Steel ball bearings are the most popular type of ball bearing; however, they are also available in other steel alloys, ceramics, and plastics.


As a major ball bearing distributor, MMB Bearings offers a wide variety of ball bearings to suit virtually any application and industry requirements.
