Welcome to Linqing Hangce Bearing Co., Ltd.



In the past, many car wheel hub bearings used single row tapered roller or ball bearings in pairs. With the development of technology, car wheel hub units have been widely used in cars. The range and quantity of wheel bearing units are increasing day by day, and now they have developed into the third generation: the first generation consists of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, and the bearing can be simply sleeved on the axle and fixed with a nut. Makes car maintenance easier. The third-generation wheel hub bearing unit is a combination of the bearing unit and the anti-lock brake system ABS. The hub unit is designed with an inner flange and an outer flange, the inner flange is bolted to the drive shaft, and the outer flange mounts the entire bearing together. Worn or damaged hub bearings or hub units can cause undue and costly failure of your vehicle on the road, or even harm your safety.

Please pay attention to the following matters in the use and installation of wheel hub bearings:

1. In order to ensure maximum safety and reliability, it is recommended that you check the wheel hub bearings frequently regardless of the age of the vehicle - pay attention to the early warning signs of bearing wear: including any frictional noise during rotation or Unusual deceleration of the suspension combination wheel during cornering. For rear-wheel drive vehicles, it is recommended that the front wheel hub bearings should be lubricated when the vehicle travels to 38,000 kilometers. When replacing the brake system, check the bearings and replace the oil seal.

2. If you hear the noise from the hub bearing, first of all, it is important to find the place where the noise occurs. There are many moving parts that may produce noise, and it may also be that some rotating parts are in contact with non-rotating parts. If it is confirmed that it is the noise in the bearing, the bearing may be damaged and needs to be replaced.

3. Because the working conditions of the bearings on both sides of the front hub are similar, even if only one bearing is damaged, it is recommended to replace it in pairs.

4. The hub bearing is more sensitive, and in any case, the correct method and suitable tools need to be used. In the process of storage, transportation and installation, the components of the bearing cannot be damaged. Some bearings require greater pressure to be pressed in, so special tools are required. Be sure to refer to the car manufacturer's manual.
