Introduction to ball bearings

Rolling bearings are an important component of rotating or oscillating machine elements. They help to support and guide rotational movements and transfer loads between different components such as axles, shafts and wheels.

A ball bearing is a rolling bearing with a ball rolling element. The balls are located in an annular raceway or groove, resulting in a relatively low contact area. The reduced contact area reduces friction, but limits the weight that can be carried by the bearing. Ball bearings are traditionally used in high-speed, low-load applications where their reduced friction, noise and vibration help to prevent excessive wear.

Ball bearings can usually carry radial loads or loads perpendicular to the shaft. Although some ball bearing types can withstand axial loads (parallel to the shaft), they are usually limited to very low load carrying capacities.

What is a deep groove ball bearing?

Deep groove ball bearings are similar to conventional bearings, but have raceways that closely match the size of the balls running in them. These deep grooves make the balls more stable than shallow groove bearings and can withstand higher loads. They still provide low friction and the deep grooves also limit vibration and noise, while still providing some axial load capacity.
If you've ever seen any type of ball bearing, chances are you've seen a deep groove ball bearing. Due to their versatility, availability and low friction, these bearings are the most common. They are ideal for high speeds and offer a variety of advantages over other ball bearing types.
Available in a wide range of designs, sizes and load carrying capacities, these bearings are ideal for domestic or industrial use. In addition, replacing conventional bearings with deep groove ball bearings is simple and can increase the life and efficiency of your machine.

Types of deep groove ball bearings

Over the years, manufacturers have improved the design of deep groove bearings, resulting in several different types. These types are often better suited to specific applications for which deep groove bearings are not suitable.

Single row deep groove ball bearings
These are typically deep groove ball bearings with a single raceway. They are usually robust and made from durable materials, ensuring that these bearings have a longer service life.

Single row deep groove ball bearings are also subdivided into other types with bore diameters ranging from 3 mm to 400 mm, making them suitable for almost any application. Some manufacturers will also offer thin, narrow, wide or miniature bearings depending on the customer's needs.

As deep groove ball bearings are subjected to extreme conditions, manufacturers also offer ceramic coated bearings to handle electrical pitting and high temperature installations that can withstand up to 660 degrees Fahrenheit.

One of the latest developments in single row deep groove ball bearings is the sensor bearing unit, which measures the condition of the ball bearing components. These units are simple to use and help with speed sensing, angular position measurement and steering, making them suitable for use in electric motors, tractors, conveyors and road rollers.

Sealed deep groove ball bearings
Sealed deep groove ball bearings are similar to single row bearings, except that they are fitted with steel or rubber shields on one or both sides of the bearing. These seals are pre-lubricated with grease to extend the life of the bearing.

Many manufacturers use sealed ball bearings in contaminated environments where the performance of the bearing might otherwise be compromised. The shrouds help the bearing to retain its grease and also prevent any contaminants from entering the bearing itself.

Larger deep groove ball bearings can even have machined brass cages for high speed applications where the cage prevents unnecessary wear.

Flanged deep groove ball bearings
Some deep groove ball bearings have a flanged outer ring which works in a similar way to the snap ring on a standard ball bearing. Flanges improve the operational efficiency of the bearing and are also easier to machine due to the simplicity of the bearing housing bore.

Flanged deep groove ball bearings are ideally suited to carrying axial loads, for example on tube ends or belt guide rollers. Some variants even have rotating housings to allow for slight misalignment and better axial loads.

Double-row deep groove ball bearings
The double-row design provides a significant increase in load carrying capacity while still maintaining the low friction characteristics of the bearing. Double-row bearings are usually slightly wider than single-row bearings, making them almost as versatile and practical.

The main disadvantage of double row deep groove ball bearings is that they do not have seals or shields, although some may be fitted with cages. These cages facilitate mounting and assembly, but are susceptible to mechanical stress during operation. Selecting the correct type of cage for a particular application is essential, particularly where certain cage materials are sensitive to particular lubricants.

Largest ball bearings
These ball bearings have more rolling elements than their single-row and double-row counterparts. These extra balls allow for higher performance and greater precision without sacrificing efficiency or life. As with single row deep groove ball bearings, they can be open or shielded, depending on the application and requirements.

Benefits of deep groove ball bearings

Deep groove ball bearings offer several advantages over conventional ball bearings. These include

Ability to withstand radial and axial loads
One of the most significant disadvantages of conventional ball bearings is their inability to withstand axial loads. Most deep groove ball bearings can carry approximately 50% of their radial load in the axial plane, although some smaller bearings can only carry approximately 25% of the radial load. This ability to withstand both axial and radial loads makes deep groove ball bearings very versatile and makes them popular in a variety of industries.

Low friction
Deep groove ball bearings generate less friction than standard bearings, which can save money in a number of ways. Firstly, it reduces the operating temperature of the bearing, thereby extending its service life. It also becomes cheaper to operate machines with bearings because of the increased efficiency and reduced maintenance requirements. Low friction also reduces noise and vibration, making these bearings ideal for high rotational environments, and they use less lubrication than conventional bearings.

Easy to mount
Deep groove ball bearings are easy to mount, which simplifies assembly and increases load carrying capacity. Many manufacturers take advantage of deep groove ball bearings and reduce the housing size of machinery, resulting in smaller, lighter components. Deep groove ball bearings can also be mounted in conventional housings, making it simple to replace conventional ball bearings with their superior counterparts.

These ball bearings are not limited to industrial use; they are also a common component of items in your home. Any appliance with a motor has at least one deep groove ball bearing, including washing machines, clothes dryers, hoovers and dishwashers.

They are also found in computer fans, pool pumps and even skateboards. Even fingertip gyroscope toys consist of multiple ball bearings, allowing the toy to rotate in multiple directions.

Most of these deep groove ball bearings have a shielded design, which means they do not require constant lubrication or maintenance. Some, however, are openings and the addition of some suitable lubricant can extend the life and effectiveness of the bearing. Fortunately, ball bearings are also cheap and easy to replace if necessary.
