Automobile hub bearing is one of the important parts of automobile, which plays the role of supporting wheel rotation and transmitting power. Below I will introduce the structure, function and characteristics of automotive hub bearings in detail.Structure: Automotive hub bearings are usually composed of several parts, such as an inner ring, an outer ring, a rolling element (such as a steel ball or roller), a cage and a seal. The inner ring is the part connected to the axle, and the outer ring is connected to the wheel.

Hub bearing (HUB) is the main role of load-bearing and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important component. The traditional automobile wheel bearing is composed of two sets of tapered roller bearing or ball bearing. The installation, oiling, sealing and clearance adjustment of the bearing are all carried out on the automobile production line.

Hub bearings can fix the tire and support the gravity of the whole body, provides precise guidance for the rotation of the hub. wheel hub bearing enables the wheels and attached components to rotate smoothly and keeps the wheel attached to the car. High quality wheel hub assembly make you enjoy your vehicle in a safe and smoothWheel bearing assemblies manufactured by high-quality materials for ensuring precisely matches, durability, reliability and premium performance.

The DAC type auto front wheel bearing is a double row angular contact ball bearing incorporating an integral outer ring and two separable inner rings; which is available either with seals or without seals. Wheel bearings (hub bearing) main role is to load and for the rotation of the hub to provide accurate guidance, both axial load radial load again, is a very important component. Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearings combination, bearing installation, oiled, and adjust the clearance seals are conducted in automotive production line.

Features: (1) High strength and wear resistance: wheel bearings are usually made of high-strength alloy steel or stainless steel, with good wear resistance and pressure resistance, can withstand the high load and friction when the vehicle is running; (2) Good sealing: the seals in the hub bearing structure can effectively prevent external dust, water, impurities, etc.

The fourth generation hub bearing unit is to make the constant speed universal joint and bearing into a whole, which solves the defect of increasing the size of the hub due to the integrated structure of the hub and the constant speed universal joint in the prior art. The development of the fourth generation hub bearing unit has been successful, and it is believed that it will be widely used in various types of automobiles in the near future.

The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It combines two sets of bearings into one, with good assembly performance, clearance adjustment can be omitted, light weight, compact structure, and high load capacity.

Truck hub units, which contain two tapered roller bearings, are pre-adjusted, greased and sealed at the factory in order to simplify installation. The wheel bearing units are intended for use in truck, trailer and buses. They are designed to withstand typical harsh operating conditions and require less maintenance than the conventional wheel bearing sets they replace. Some variants have an integrated impulse ring which makes some variants suitable for use with anti-lock braking systems.

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space.
