Applications

In the past, many car wheel 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 scope and usage of wheel hub bearing units are growing day by day, and now it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing. The bearing can be simply put on the axle and fixed with nuts. Makes car maintenance easier. The third generation wheel hub bearing unit uses a bearing unit that matches the anti-lock braking system ABS. The hub unit is designed with an inner flange and an outer flange. The inner flange is fixed on the drive shaft with bolts, and the outer flange installs the entire bearing together. Worn or damaged wheel bearings or wheel hub units can cause inappropriate and costly failures of your vehicle while driving, and even cause harm to your safety.

Please pay attention to the following matters when using and installing wheel hub bearings:

To ensure maximum safety and reliability, it is recommended that you check your wheel bearings frequently regardless of the age of your vehicle - look out for early warning signs of bearing wear: including any friction noise when turning or suspension combination wheels that do not move when turning. Normal deceleration. For rear-wheel drive vehicles, it is recommended that the front wheel hub bearings be lubricated when the vehicle reaches 38,000 kilometers. When replacing the brake system, inspect the bearings and replace the oil seals.

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

Because the working conditions of the front hub that cause bearing failure on both sides are similar, it is recommended to replace the bearing in pairs even if only one bearing is broken.

Wheel bearings are sensitive and require correct methods and the right tools in any situation. During storage, transportation and installation, bearing components must not be damaged. Some bearings require greater pressure to be pressed in, so special tools are required. Be sure to refer to the vehicle manufacturer's instructions.
