Four-point contact double row ball bearings

The advantages of four-point contact double-row ball bearings mainly include the ability to withstand bidirectional axial loads, automatic self-alignment, and high rigidity, and its characteristics include high precision and wear resistance.
Strong load-bearing capacity:

The raceway designed for four-point contact double-row ball bearings can support axial loads acting in two directions, making it more widely applicable in applications. At the same time, it can also withstand limited radial loads when the axial force is given.
Automatic self-aligning performance:

Due to its automatic self-aligning performance, four-point contact double-row ball bearings can be used in various working conditions, including axial, radial, tilting or torsional deformation, which makes its application in complex working conditions more extensive and reliable.
High rigidity:

The inner and outer ring raceways of the four-point contact single-row ball bearing are peach-shaped cross-sections, which increase the radial load capacity and have good axial limiting capabilities in two directions. Its axial clearance is relatively small and the contact angle is large, so the bearing has high rigidity.
