Double Row Deep Groove Ball Bearing Size Chart
Introduction
Double row deep groove ball bearings are commonly used in various applications, including automotive, industrial, and agricultural machinery. They are designed to handle radial and axial loads simultaneously, making them suitable for high-speed and heavy-duty operations. In this article, we will discuss the double row deep groove ball bearing size chart and its significance in selecting the right bearing for your application.
What is a Double Row Deep Groove Ball Bearing?
A double row deep groove ball bearing consists of two rows of balls arranged in a deep groove raceway. The inner and outer rings of the bearing are separable, making it easy to mount and dismount. The bearings are available in different sizes, ranging from small bearings used in electric motors to large bearings used in heavy-duty machinery.
Double Row Deep Groove Ball Bearing Size Chart
The size of a double row deep groove ball bearing is determined by its inner diameter, outer diameter, and width. The size chart provides the standard dimensions for each bearing size. The standard sizes are designated by a series of numbers that indicate the bearing bore diameter and the outside diameter. For example, a bearing with a bore diameter of 20mm and outside diameter of 47mm would be designated as 20x47x14.
The first number in the designation indicates the bore diameter, the second number indicates the outside diameter, and the third number indicates the width. The width of the bearing is also known as the thickness or height, depending on the orientation of the bearing.
The size chart for double row deep groove ball bearings includes a wide range of sizes, from small bearings with bore diameters as small as 10mm to large bearings with bore diameters over 100mm. The width of the bearings also varies, from 12mm for small bearings to 45mm for larger bearings.
Significance of the Size Chart
The double row deep groove ball bearing size chart is significant in selecting the right bearing for your application. The size of the bearing determines its load-carrying capacity, speed capability, and other performance characteristics. Using the wrong size of the bearing can result in premature failure, reduced performance, and safety hazards.
By referring to the size chart, you can determine the correct size of the bearing for your application. You can also compare the dimensions of different bearings to select the most suitable one for your needs. The size chart also provides information on the maximum load capacity, maximum speed, and other specifications for each bearing size.
Factors to Consider in Bearing Selection
When selecting a double row deep groove ball bearing, there are several factors to consider. These include the load type, speed, temperature, lubrication, and mounting arrangement. The load type can be radial, axial, or a combination of both. The speed can be high or low, and the temperature can range from ambient to high.
The lubrication method is also important in bearing selection. The bearing can be lubricated with grease or oil, depending on the application requirements. The mounting arrangement can be fixed or floating, and the bearing can be installed with different types of seals and shields to protect it from contamination.
Conclusion
The double row deep groove ball bearing size chart is an important tool in selecting the right bearing for your application. By referring to the size chart and considering the various factors that affect bearing selection, you can ensure that your equipment operates efficiently and safely. Always consult with a bearing specialist if you are unsure about the correct bearing size or type for your application.
