Double Row Angular Contact Ball Bearings
Double row angular contact ball bearings are a type of bearing that can accommodate both radial and axial loads in both directions. They have two rows of balls arranged in a back-to-back or face-to-face configuration, which allows for increased load-carrying capacity and improved rigidity compared to single row angular contact ball bearings. Here is some information about double row angular contact ball bearings based on the search results:
Features of Double Row Angular Contact Ball Bearings:
1. Design: Double row angular contact ball bearings consist of two rows of balls, separated by a central spacer, and are mounted in a single outer ring. The inner rings are usually extended on both sides to provide additional support.
2. Load Capacity: These bearings have a higher load-carrying capacity compared to single row angular contact ball bearings due to the increased number of balls and contact points.
3. Axial Rigidity: Double row angular contact ball bearings offer improved axial rigidity, making them suitable for applications that require precise axial guidance and resistance to tilting moments.
4. Contact Angle: The contact angle of double row angular contact ball bearings is typically 30°, but other contact angles, such as 25° or 40°, are also available depending on the specific application requirements.
5. Cage Options: Double row angular contact ball bearings are available with different cage materials, such as pressed steel, machined brass, or polyamide, depending on the desired level of strength, temperature resistance, and lubrication.
Applications of Double Row Angular Contact Ball Bearings:
1. Machine Tools: These bearings are commonly used in machine tool spindles, where they provide high rigidity and precision for the machining process.
2. Industrial Gearboxes: Double row angular contact ball bearings are suitable for use in industrial gearboxes, where they can handle both radial and axial loads generated by the gears.
3. Electric Motors: These bearings are used in electric motors, where they provide support for both radial and axial loads, ensuring smooth and efficient motor operation.
4. Material Handling Equipment: Double row angular contact ball bearings are utilized in material handling equipment, such as conveyors and cranes, where they can handle both radial and axial loads during the movement of heavy loads.
