If you are from an industrial background or getting a head start in this field, you might already know that you are bound to find out many different tools and requirements. Ball bearings are one of those requisites. While we might have heard about this somewhere, you will need to know more about this tool to get started in this business. Stick around the article to understand its necessity and utility.

What Are Ball Bearings?

Ball bearings are spinning devices that bear the weight, decrease friction, and align mobile parts of machines while not restricting movement. It is made up of a series of spheres that act as rotating components. They are confined to two circular metal pieces. These metallic bits are referred to as races or bearing rings.


Ball bearings are designed to provide efficiency in the industry. These are composed of four primary components–two races, the rolling element, and the ball separator.

The internal race is open to spin, but the outer race remains fixed. These are fashioned in a way to bear loads that are perpendicular to the rotary axis and this kind of force is often termed radial loads.

The role of the separator is to act as a barrier between the balls, preventing them from colliding. This is positioned between the balls.

A double-row bearing ball design contains two rows of bearing balls. One benefit of double-row bearings over single-row ones is their capacity to manage radial and axial strains in both directions.

Main Purpose of Ball Bearings

The primary function of bearings is to avoid direct metal-on-metal interaction between two parts in motion. This reduces surface tension, heat production, and, eventually, mechanical wear and tear. It moreover conserves energy since sliding force is substituted with rolling which contributes very less friction.

They likewise transfer the spinning element’s stress to the housing. This load could be either radial, axial, or both. A bearing also limits the free movement of mechanical components to predetermined angles.


There are many advantages of this simple component in the industrial business–

  • provides resistance to wear and tear
  • does not demand constant lubrication
  • works for extended periods
  • can be replaced effortlessly
  • cheap compared to other alternatives
  • deters energy loss by reducing friction between surfaces
  • intuitive design
  • bears thrust loads

Types of Ball Bearings

There are many kinds of ball bearings that meet specific requirements, generally the magnitude of the service–

  • Angular Contact Ball Bearing-

These ball bearings feature raceways for both inner rings and outer rings that are shifted relatively with the other in the direction of the bearing axis. This implies that these bearings are designed to withstand a combination of loads.

Along with deterring contamination, these act as excellent lubricants.

  • Deep Groove Ball Bearing-

Deep groove ball bearings are widely utilized in many industries. They are available in different arrangements. They also hold up heavy loads. These ball bearings provide both axial as well as radial support.

  • Duplex Ball Bearing-

These kinds of bearings are manufactured by a blend of two angular bearings. The possible blends are back-to-back and face-to-face. Both of these combinations are designed to be able to support axial and radial loads in any direction.

  • Miniature Bearings-

As the name suggests, these are tiny bearings where the rolling elements are balls. Also known as micro bearings or instrument bearings with all the rings, balls and retainers, these bearings are employed for industrial, medical, and other purposes that prioritize accuracy.

  • Precision Ball Bearings-

Precision ball bearings provide additional precision and have better tolerance levels. These bearings are best suited for high-speed and precision in guidance. There are two main variations in this kind of bearing– angular contact bearings and deep groove bearings. They have the potential to handle all kinds of loads.

Why Use of Stainless Steel In Ball Bearings

The use of stainless steel is recommended in places that risk corrosion. Chrome steel bearings and other kinds are likely to rust easily. Stainless steel exhibits exceptional resistance to corrosion and saltwater. These are even less expensive than glass balls. Stainless steel has stronger resilience at high temperatures, which could assist you in keeping performance targets and extending component life over ordinary steel. By using stainless steel ball bearings, you will be able to increase productivity and efficiency in your industry in many ways.
