Product Description

A wheel hub bearing, also known as a hub assembly or wheel bearing assembly, is a critical component found in automotive vehicles. It is responsible for enabling smooth and frictionless rotation of the wheels while supporting the weight of the vehicle.Hub bearing is the main role of bearing and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important parts. The traditional automobile wheel bearing is composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are carried out on the automobile production line.

Preload is a deliberate axial load applied to a bearing to eliminate internal clearance and ensure proper contact between rolling elements and raceways. Preloading hub bearings enhances their stiffness, reduces internal play, and improves the overall system's responsiveness. It is commonly used in applications that require high precision, such as machine tools or spindle bearings. Preload can be achieved through various methods, including axial spring arrangements, shims, or adjusting the bearing components' position. The amount of preload applied depends on factors such as the bearing type, size, and application requirements.

 Hub bearings often require effective sealing to prevent the ingress of contaminants, such as dirt, water, or debris, and to retain lubrication. Seals are designed to provide a barrier between the internal bearing components and the external environment. Common types of seals used in hub bearings include contact seals (such as rubber seals or lip seals) and non-contact seals (such as shields or labyrinth seals). The choice of seal depends on factors such as the operating conditions, required level of protection, and the desired balance between sealing effectiveness and frictional losses.
