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.

Hub bearings often feature seals or shields to protect the internal components from contaminants such as dust, dirt, and water. Seals are typically made of rubber or synthetic materials and provide a physical barrier against external elements. Shields, on the other hand, are metal plates that cover part of the bearing and offer protection while allowing for some degree of lubricant flow. Seals and shields help prolong bearing life by reducing the risk of contamination-induced damage.

Bearing Preload: Preload is a controlled amount of axial load applied to a bearing to eliminate any internal clearances and ensure proper contact between the rolling elements and raceways. Preloading enhances the stiffness and operating precision of the bearing assembly, particularly in applications with high vibration or load variations. Proper preload adjustment is critical as insufficient preload can lead to excessive play or misalignment, while excessive preload can cause increased friction, heat generation, and premature wear.
