Double Inner Ring Double Row Angular Contact Ball Bearings

Introduction to Double Inner Ring Double Row Angular Contact Ball Bearings

Double inner ring double row angular contact ball bearings are specialized types of bearings designed to handle combined radial and axial loads.

These bearings are commonly used in applications where there are higher axial loads or where the axial and radial loads need to be accommodated simultaneously. The double inner rings provide additional support and stability.

The specific application and performance requirements, such as speed, temperature, and load conditions, will influence the selection of the appropriate type and size of the bearing. Manufacturers often provide detailed specifications and guidelines for the selection and use of their bearings in various applications.

Features

1. Compact structure: Due to the double inner ring design, the radial size of the bearing is small, which can maximize the bearing capacity in a limited installation space.

2. High rigidity: The contact angle of double inner ring double row angular contact ball bearings is generally 45° or 90°. This design makes the bearings have high rigidity and good load-bearing capacity.

3. High speed: Since the contact area between the balls and the inner and outer rings is small and the distance between the balls is long, the bearing has low friction resistance and can withstand high speeds.

4. Good stability: The inner and outer rings of double inner ring double row angular contact ball bearings are connected through balls, so the relative position between the inner and outer rings will not change, thus ensuring the stability of the bearing.
stability.

5. Wide scope of application: Double inner ring double row angular contact ball bearings can withstand both radial loads and axial loads, so they are widely used in various mechanical equipment.
