Double Row Angular Contact Ball Bearings An Overview Double row angular contact ball bearings are critical components in various industrial applications, providing essential support and reducing friction between moving parts. These bearings are designed to accommodate both axial and radial loads, making them suitable for high-performance environments. Design Characteristics The distinctive feature of double row angular contact ball bearings is their geometry, which allows them to handle loads from multiple directions. This is achieved through the arrangement of the balls in two rows, each oriented at an angle to the bearing axis. This configuration enables the bearing to support axial loads in both directions, making it an ideal choice for applications where such loads are prevalent. These bearings are typically constructed from high-quality materials, ensuring durability and robustness. Commonly used materials include high carbon chrome steel, stainless steel, and bearing bronze, each selected for their specific mechanical properties and resistance to wear. The inner and outer rings of these bearings are precisely machined to enhance performance and reliability. Applications Double row angular contact ball bearings find extensive use in a variety of industries. They are commonly employed in the automotive sector for wheel hubs, steering mechanisms, and transmission systems . In the aerospace industry, these bearings are used in landing gear and engine components, where load capacity and reliability are critical. In addition, they are utilized in manufacturing equipment, such as gearboxes, pumps, and motors. The ability to handle combined loads makes them highly suitable for these applications, where both axial and radial forces are at play. Other notable applications include electric machines, agricultural machinery, and various construction equipment. double row angular contact ball bearing catalogue Advantages The advantages of double row angular contact ball bearings are considerable.
