Product Detail

The front-rear wheel hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. Hub bearings are components used at the axles of automobiles to support load and provide precise guidance for the rotation of the hub. They bear both axial load and radial load, and are an important part of automobile load and rotation.

Automobile wheel hub bearings are double-row angular contact ball bearings, which have the characteristics of double-row angular contact ball bearings. Generally, they adopt double-half inner ring structure with a large base number, which is easy to assemble and ensure bearing clearance.

Characteristics of bearing conditions

1. Carrying requirements

To withstand the combined load caused by the weight of the vehicle, road impact, and lateral turning;

Adapt to the environment

1. The periphery of the bearing is full of water vapor and dust;

2. Bearings are often in contact with mud;

3. Bearings will be used in high temperature and high cold areas.

Wheel bearings support the weight of the vehicle and allow the tires to turn smoothly. They are important because they have a major impact on safety, ride comfort and fuel efficiency. At the same time, their working environment is more complicated, and they have higher requirements on the material of the bearing.
