With the advancement of science and technology, hub bearings are gradually integrated into the hub and axles, and the degree of integration is getting higher and higher with the development of technology. The hub bearing has also become unitized and integrated, and the hub unit is the part that bears the load of the car body and provides rolling support for the rotation of the wheel. During operation, it mainly bears the axial load, radial load and a certain tilting moment. The general speed of hub bearings is 0~1000rpm, and the operating temperature range is -40~120 ℃. The hub unit is generally lubricated with full- sealed grease.
