Deep Groove and Double-Row Deep Groove Ball Bearings
Deep groove and double-row deep groove ball bearings are the most common and popular type of rolling bearing. They are used in a wide range of applications due to their versatility and ease of installation. Deep groove and double-row deep groove ball bearings consist of an outer ring, inner ring, ball and cage. The inner ring and outer ring typically have curved raceways in which the ball travels. Depending on the application and usage, these bearings can be made of a variety of materials such as steel, ceramic, and plastic.
Deep groove and double-row deep groove ball bearings employ either ball or roller elements to produce low friction sliding contact pockets. This contact area creates a smooth rolling motion for a variety of applications, including high-speed machine tools, electric motors, and machine tool spindles.
The design and fabrication of deep groove and double-row deep groove ball bearings is primarily done to achieve higher load-bearing capacity than other rolling bearing types. They are relatively stiff and accept high levels of radial and axial loading. The design of these bearings also compensates for misalignment in the shaft and housing. This is beneficial in terms of reducing vibration and wear at the contact area of the bearing.
Deep groove and double-row deep groove ball bearings come in a variety of sizes and design configurations. These bearings are typically constructed with precision and quality materials to ensure optimal performance during operation. The outer and inner rings are typically made of high-grade carbon steel and are hardened. The ball and cage are made from a hard, resilient material, typically hardened steel or ceramic, which can handle heavy loads without deforming.
In addition, deep groove and double-row deep groove ball bearings can be equipped with seals to protect against dirt, dust and other contaminants. They also offer protection against lubricant leakage and corrosion. The seals also prevent the passage of oil fumes, which may cause bearing corrosion and whirring noise.
Overall, deep groove and double-row deep groove ball bearings are well suited for a wide range of applications. Their versatile design offers high load-bearing capacities and low rolling friction, while their precision construction ensures optimal performance and long life. Additionally, their ability to adapt to misalignment and to be sealed against contaminants make them suitable for environment-sensitive applications.
