What is a ball bearing used for?
Learn about the importance of ball bearings in today's industry.
This comprehensive guide will discuss the uses, types, and benefits of ball bearings to help you decide on what type of ball bearing to use for your needs.
Ball bearings are the unsung heroes of modern machinery.
Without them, many everyday devices would be powerless and motionless.
Ball bearings are small round metal parts that allow two circular objects to move smoothly against each other with reduced friction.
Think of a ball bearing like a tiny basketball court with two players: one stationary and one spinning around it.
In this analogy, the stationary part is called the "inner race" while the spinning one is known as the "outer race."
The basketballs are tiny steel balls that move within the races and provide a cushion between them.
With these parts, ball bearings can reduce friction and allow for the smooth motion of objects.
If it weren't for these tiny helpers, many of our appliances and machines wouldn't work as well.
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the moving parts of the bearing.
Ball bearings are used in a wide variety of applications, from automotive engines and transmissions to computer hard drives and power tools.
Ball bearings reduce friction, enabling faster speeds and smoother operation in devices with rotating or oscillating components.
They are also used in a wide range of industrial applications, such as conveyor systems, elevators, and other machinery.
The next section covers the basic functions of a ball bearing, how and where it's used, the types of ball bearings, and the advantages of using them.
Definition of a ball bearing
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the moving parts of the bearing.
The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads.
It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
In most applications, one race is stationary and the other is attached to the rotating assembly.
As one of the bearing races rotates it causes the balls to rotate as well.
Because the balls are rolling, they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.

Types of ball bearings
Single-row ball bearings
Single-row ball bearings are commonly used in applications requiring low friction and minimal noise.
These bearings come with either an open or sealed design, depending on the environment they will be operating.
Open single-row ball bearings allow for a greater degree of lubrication to reduce friction and wear, whereas sealed designs provide improved protection from dirt and moisture.
Single-row ball bearings are designed to provide high precision and low noise operation, allowing them to be used in a range of applications including automotive, agricultural, and medical applications.
They are also easy to maintain and can be used in a variety of complex applications.
Double-row ball bearings
Double-row ball bearings are a type of bearing used to support radial and axial loads.
These bearings consist of two rows of round steel balls held together by an inner and outer ring.
The balls roll along the grooved tracks on the rings, allowing the bearing to rotate with minimal friction.
Double-row ball bearings offer higher load-carrying capacity than single-row bearings and are typically used in applications where radial and axial loads must be supported at the same time.
They can also be used in applications where vibration levels are high, as the inner and outer rings absorb the vibrations more effectively than a single-row bearing would.
Angular contact ball bearings
Angular contact ball bearings are a type of rolling-element bearing that uses angular contact to reduce friction and provide additional support for radial loads.
They can accommodate both axial and radial forces, making them suitable for high-speed applications such as electric motors and pumps.
Angular contact ball bearings have higher capacity than deep groove ball bearings, allowing them to handle higher loads and speeds.
They are also used in applications where the misalignment of shafts is a concern, as the angular contact provides additional support.
Angular contact ball bearings can be used in a variety of applications, from automotive and aerospace to medical equipment and industrial machinery.
Self-aligning ball bearings
Self-aligning ball bearings are a type of bearing designed to reduce misalignment in industrial equipment.
They are equipped with two rows of balls, inner rings, and outer rings which contain concave raceways that allow the bearing to move along an axis.
The spherical shape of the balls provides a self-adjusting feature so the bearings can adjust to small misalignments of the shaft.
Self-aligning ball bearings are also designed with deep grooves in the inner and outer rings, which helps to provide superior axial and radial load capacity.
The bearing also offers good low-friction performance and is well-suited for applications with high dynamic loads.
The low friction of self-aligning ball bearings provides for energy-efficient operation and helps to reduce operating costs.
Thrust ball bearings
Thrust ball bearings are ideal for applications such as automobiles, aircraft, ships, and heavy machinery.
They consist of two equally-spaced grooves in the outer ring, into which hardened and ground balls can rotate.
The inner ring is typically made from steel or brass. Thrust ball bearings also have a high load-carrying capacity and are capable of withstanding heavy thrust loads in one direction.
They are usually able to operate at higher speeds than other types of bearings due to the greater number of balls used, and they also have lower friction compared to other bearing types.
Furthermore, they require less maintenance than roller bearings or cylindrical bearings.
Applications of ball bearings
Automobiles
Ball bearings are essential components in automobiles. They are used to reduce friction between moving parts, enabling smoother and more efficient operation of engines and car systems.
