Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds. Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.

Wheel bearing are one of the most crucial components of a car's suspension. Wheel hub bearing is used to carry and rotate the hub on the automobile axle to provide accurate guidance parts, both axial load and radial load, this kind of bearing is an important part of the automobile load and rotation. Hub bearing is one of the key parts of the automobile, its main role is to carry weight and provide accurate guidance for the rotation of the hub, which requires it to bear not only axial load but also radial load.

A wheel hub assembly (WHA), also referred to as hub assembly，wheel hub unit,wheel hub bearing, is an automotive part used in most cars, passenger vehicles, and light and heavy trucks. The main function of the hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. Especially for the wheel hub bearings of trucks, due to the greater load it bears, the bearing capacity and precision of the wheel hub bearings are even more important.   

Linear guide bearings, also known as linear bearings, are also rolling parts that can do linear reciprocating operation. The sliding guide has the advantages of simple structure, convenient manufacture and high contact stiffness.

Thrust ball bearings are designed to withstand thrust loads at high speeds and are composed of gasket rings with ball rolling raceway grooves. Because the ring is the seat pad shape, the thrust ball bearing is divided into two types: flat base pad type and aligning spherical seat type. In addition, this bearing can withstand axial loads, but not radial loads.

Universal joint is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft.
