3205-BD-XL-TVH-L285 double row angular contact ball bearing FAG

A double row angular contact ball bearing is a type of rolling-element bearing designed to accommodate combined radial and axial loads in both directions. It consists of two rows of balls, typically separated by a cage or a separator to maintain equal spacing between the balls. The inner and outer raceways of the bearing rings are designed to enable angular contact between the balls and the raceways.

Key features and characteristics of a double row angular contact ball bearing include:

1. Angular Contact: The design allows for the bearings to withstand both radial and axial loads by supporting the forces at an angle, improving load distribution.
2. Double Row Configuration: With two rows of balls, these bearings can accommodate higher radial loads compared to single-row bearings.
3. Axial Load Capacity: The arrangement of the balls in an angular contact bearing enhances its ability to handle axial loads in both directions.
4. Different Contact Angle Options: These bearings may have varying contact angles (usually between 25° and 40°), affecting their suitability for different applications. Higher contact angles offer greater axial load capacity but may compromise radial load capacity.
5. Cage or Separator: A separator or cage is used to maintain ball spacing, preventing contact between balls and reducing friction.
6. Precision and Speed: They are often used in applications requiring high precision and moderate to high-speed operations, such as machine tool spindles, gearboxes, and pumps.
7. Versatility: Their ability to support both radial and axial loads makes them suitable for various applications across different industries.
8. Sealing and Lubrication: Like other bearings, they require proper sealing and lubrication to minimize wear and friction and ensure optimal performance and durability.

These bearings come in various sizes and configurations, and the specific design and features can vary based on the intended application and industry requirements.

They are commonly used in machinery that demands both radial and axial load support, providing reliability and performance in a wide range of industrial applications.
