Introduction
Deep groove ball bearings are the most common type of rolling element bearing in the world, accounting for approximately 80% of all bearing sales. Their simple design, high load capacity, and long service life make them ideal for a wide range of applications, from automotive to aerospace.
Construction
Deep groove ball bearings consist of an inner ring, an outer ring, a set of balls, and a cage. The balls are located in a deep groove in the inner and outer rings, allowing for radial, axial, and moment loads. The cage keeps the balls evenly spaced and prevents them from slipping out of the groove.
Types
There are many different types of deep groove ball bearings, each with its own unique characteristics. Some of the most common types include:
Applications
Deep groove ball bearings are used in a wide range of applications, including:
Advantages
Disadvantages
Selection
When selecting a deep groove ball bearing, it is important to consider the following factors:
Installation
Deep groove ball bearings are relatively easy to install. However, it is important to follow the manufacturer's instructions carefully to avoid damaging the bearing.
Maintenance
Deep groove ball bearings require very little maintenance. However, it is important to inspect them periodically and to lubricate them as needed.

FAQs
A deep groove ball bearing is a type of radial ball bearing. Radial ball bearings are designed to handle radial loads, while deep groove ball bearings can handle both radial and axial loads.
Single-row deep groove ball bearings have one row of balls, while double-row deep groove ball bearings have two rows of balls. Double-row deep groove ball bearings have a higher load capacity and stiffness than single-row deep groove ball bearings.
Open deep groove ball bearings have no seals or shields. Shielded deep groove ball bearings have seals or shields on one or both sides to protect the bearing from dirt and contamination.
Deep groove ball bearings are relatively easy to install. However, it is important to follow the manufacturer's instructions carefully to avoid damaging the bearing.
Deep groove ball bearings should be lubricated periodically to reduce friction and wear. The type of lubricant used will depend on the application.
Deep groove ball bearings should be inspected periodically for signs of wear or damage. If any damage is found, the bearing should be replaced.
Conclusion
Deep groove ball bearings are a versatile and reliable bearing type that can be used in a wide range of applications. By understanding the different types of deep groove ball bearings and their advantages and disadvantages, you can select the right bearing for your application.
Table 1: Deep Groove Ball Bearing Types
Type | Description |
---|---|
Single-row | The most basic type of deep groove ball bearing. They are available with open or shielded ends. |
Double-row | Have two rows of balls, providing higher load capacity and stiffness than single-row bearings. |
Angular contact | Designed to handle axial loads. They are available in single-row and double-row versions. |
Self-aligning | Allow for misalignment between the shaft and housing. They are available with spherical and cylindrical roller elements. |
