Ball Bearings

What are Ball Bearings?

One of the most significant components of all machines and even most household appliances is a ball bearing. It helps connect two machine components, which move relative to one another, in a smooth and frictionless motion. While there will be friction on the surface contact area, the same will not disrupt the operations of the machinery. In real life applications of ball bearings it is observed that one component will be a rotating shaft while the other will have a fixed housing.

Ball bearing is not a single component, but an assembly of different components. Primarily there are four main parts in any ball bearing. 

  • An inner ring which is shaped like a grooved track raceway.
  • An outer ring which is also grooved to form a raceway.
  • A number of hardened steel balls that run through the raceway. 
  • A retainer that acts as a ball separator.

These races have different diameters: the smaller one fits inside the larger, and the metal balls fill the space between them which can be restrained and separated using a retainer or cage. Their low friction rotary motion provides smooth operation, high performance and efficient weight management due to their spherical shape.

  • Radial Ball Bearing: This is the most common ball bearing variant which has one row of balls, designed to carry loads perpendicular to the axis of rotation. Its capacity for bearing axial, or thrust load might be greater than its radial capacity.
  • Angular-contact Bearing: This has a section of the outer-race groove, which allows the insertion of more balls. This further enhances the potential for carrying large axial loads in one direction. When paired with a complimentary bearing it can carry load in both directions.
  • Single-row Ball Bearings: Small size and easy clearance ensures no appreciable misalignments.
  • Double-row Ball Bearings: These self-aligning bearings have two rows of balls, a spherical inner surface on the outer ring.
  • Ball Thrust Bearings: Two grooved plates with balls between, a thrust bearing will help in case of high thrust based operations.

What are the Applications of Ball Bearings?

Ball bearings are almost everywhere. You would be surprised to know how many industries are running on ball bearings. 

  • Aerospace & Aircraft Control: Bearings are designed for aerospace applications and aircraft controls. These industries require ball bearings, roller bearings and needle roller bearings. There are specific customised bearings made for jet engines and helicopters. 
  • Automotive: From tractors to motor cars and bikes, bearings are the main components holding every moving vehicle together. 
  • Railways: The entire locomotive runs on bearings and railways have specific bearing needs that are addressed to managing speed and extra load effectively. The wear and tear of quality bearings are also less.
  • Textile: The spinning mills and heavy machinery at the textile mills are run efficiently with help of bearings.  
  • Medical /Dental: From dentures to medical equipment, everything involves bearings although these bearings are the miniature versions suitable for the equipment.  
  • Engineering Equipment: From pumps, to heavy machinery on factory floors, especially those carrying high loads, high level of heat generation and in need of lubrication, all these needs are effectively fulfilled by ball bearings with minimised downtime and full productivity. 
  • Sporting and Consumer Goods: Bearings are custom made for skates, skateboards, fishing reels and rail cars.
