Deep Groove Ball Bearing Size Chart

Understanding Deep Groove Ball Bearing Sizes


Deep groove ball bearings are one of the most commonly used types of bearings across various industries. Their design allows them to accommodate both radial and axial loads, making them versatile for numerous applications. To ensure optimal performance and longevity, it is crucial to understand the various sizes available and their specific applications.


The size of a deep groove ball bearing is typically indicated by a series of numbers, which reflect the bearing's internal and external diameters as well as its width. Commonly referred to as the bearing designation, this alphanumeric code allows engineers and technicians to identify the appropriate bearing for their specific needs.


When exploring the size chart for deep groove ball bearings, several key parameters should be noted. Firstly, the outer diameter (OD) is a critical measurement, as it determines how well the bearing fits within a housing or mounting structure. The inner diameter (ID), or bore size, is equally important, as it defines the shaft size that the bearing will accommodate. Lastly, the width (W) of the bearing affects its load-carrying capacity.

For example, a bearing designated as 6204 has an inner diameter of 20 mm, an outer diameter of 47 mm, and a width of 14 mm. This standardization in sizes helps in applications ranging from small machinery to large industrial equipment. Additionally, deep groove ball bearings come in various materials, including metal and ceramic, which can impact their load capacity and resistance to environmental factors.


It is also vital to consider tolerance and clearance when selecting a deep groove ball bearing. Bearings are typically categorized into different tolerance classes, which refer to the precision with which they are manufactured. Higher precision bearings can accommodate tighter tolerances and often result in increased performance and reduced wear.


Furthermore, bearings can be classified based on their operational characteristics, such as single-row and double-row configurations. Single-row deep groove ball bearings are ideal for moderate radial loads, whereas double-row variations can handle higher loads and provide better stability.


In summary, understanding the size chart for deep groove ball bearings is essential for anyone involved in machinery design or maintenance. Accurate bearing selection ensures that machines operate smoothly and efficiently, minimizing downtime and maintenance costs. By considering factors such as inner and outer diameter, width, tolerance, and application needs, engineers can make informed decisions that enhance operational performance and extend the lifespan of machinery.
