bearing

Each wheel is equipped with a wheel bearing, a set of steel balls or rollers held by a cage in a ring of metal called a “race.” As the wheels spin, they create friction and heat. Wheel bearings help to reduce the friction, heat and protect the wheels and tires. The wheel bearing lies inside of the hub assembly.

Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing

Wheel hubs are located in the center of the car's wheels. Specifically, you can find them situated between the drive axle and brake drums. Essentially, wheel hub assemblies work to connect the wheel to the vehicle body. The assembly contains bearings, which allow the wheels to roll quietly and efficiently.

Bearings are "parts that assist objects' rotation". They support the shaft that rotates inside the machinery. Machines that use bearings include automobiles, airplanes, electric generators and so on

Wheel bearings have a very important job – enabling the rotation of your wheels. They make sure your wheels run smoothly with minimal friction. They also maintain correct wheel tracking and can even play a role in providing your vehicle's drive systems with wheel speed sensor signals.

A ball bearing is a type of rolling-element bearing that serves three main functions while it facilitates motion: it carries loads, reduces friction and positions moving machine parts. Ball bearings use balls to separate two “races,” or bearing rings, to reduce surface contact and friction across moving planes.

Center support bearings are typically located in the middle of a driveshaft and prevent it from bending or sagging under its own weight, while also relieving stress off the entire driveline.

1.small volume, light weight: Because the miniature bearing size is small, so its weight is light; At the same time,because of the advantages of simple structure,low manufacturing accuracy and easy processing,the cost of miniature bearings is low. In addition, it can be fixed directly by bolts or welding without special fixtures or fastening tools. These characteristics make micro bearings more suitable for use as key parts in precision instruments. 2. High reliability: Because of the small size and simple structure, the material requirements are usually lower; In addition, because the manufacturing process is easy to master and other reasons, its quality stability and reliability is higher (of course, compared with the ordinary rolling body there is still a certain gap). Therefore, it is a better choice for some precision mechanical parts such as crankshaft,camshaft and connecting rod of automobile engine and machine tool spindle. 3. Long service life: Due to the above reasons, the quality stability of miniature bearings is better and the service life is longer (although there is still a big gap compared with the traditional sliding fit), and with the continuous progress of technology,it has been able to achieve no lubrication or less lubrication operation (but it still needs regular maintenance).
