Hub bearing's primary role is as a load-bearing and rotating wheels to provide accurate guidance, both axial load and radial load, is a very important component. Traditional automotive hub bearings are two tapered roller bearings or ball bearing combination, the installation of the bearing, oil coating, sealing and clearance adjustment is carried out in the automotive production line. This structure makes it difficult in a car assembly plant, high cost, poor reliability, and maintenance car maintenance, but also clean the bearing, oiled and adjusted. Cubo is a standard angular contact ball bearings and tapered roller bearings on the basis of developed, it will be used as one of the two sets of bearings, with assembly performance, can be omitted clearance adjustment, light weight, compact structure, load capacity Large, sealed bearings can be pre-loaded into the grease, are omitted from the external hub seal and maintenance, etc., have been widely used in cars, in the truck also has a tendency to gradually expand the application.
Car wheel bearings are used in pairs over a maximum single row tapered roller or ball bearings. As technology advances, the car has been widely used car wheel unit. Cubo scope of use and the growing use of, has now been developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has an outer raceway for the bearing retainer flange, can simply be bearing sleeve onto the shaft with a nut. Makes the car maintenance becomes easy. Third generation wheel hub bearing unit is the use of the bearing unit and ABS anti-lock brake system compatible. Wheel hub unit designed to have a inner flange and outer flange, the flange is bolted to the drive shaft, the outer flange of the whole bearing mounted together. Worn or damaged wheel bearing or hub unit will make your vehicles in the road occurred anachronistic and costly failure, and even damage to your safety.
In order to ensure maximum safety and reliability, we recommend that you no matter how long the age of the vehicle should always check the hub bearings - note bearing for wear early warning signals: includes any grinding noise when turning wheel in a turn or suspended without portfolio normal deceleration. Rear wheel drive vehicle is recommended to 38,000 km vehicle is to deal with the front wheel hub bearing lubrication. When replacing the brake system, check the bearing and replace the oil seal.
If you hear a hub bearing parts of the emitted noise, first of all, it is important to find the noise occurs. There are many moving parts may produce noise, it may be a number of non-rotating member rotating member and the contact has occurred. If the confirmation is bearing noise, the bearing may be damaged and need replacing.
