The wheel hub bearings of cars used to use single row tapered roller or ball bearings in pairs. With the development of technology, Automobile Hub Bearing car hub unit has been widely used in cars. The application range and amount of hub bearing unit are increasing day by day. At present, it has developed to the third generation: the third generation is composed of double row angular contact bearings.
The second generation has a flange on the outer raceway for fixing the bearing, which can simply sleeve the bearing onto the axle and fix it with nuts. Automobile Hub Bearing Make the maintenance of the car easier. The third generation wheel hub bearing unit adopts the combination of bearing unit and anti lock brake 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 whole bearing together. Automobile Hub Bearing Worn or damaged wheel hub bearing or wheel hub unit will cause inappropriate and costly failure of your vehicle on the road, and even cause injury to your. Please pay attention to the following matters during the use and installation of hub bearing:
it is recommended that you always check the hub bearing no matter how old the vehicle is – pay attention to the early warning signal of bearing wear: Automobile Hub Bearing including any friction noise during rotation or abnormal deceleration of the suspension combination wheel during turning. For rear wheel drive vehicles, it is recommended that the front wheel hub bearing be lubricated when the vehicle travels to 38000 km. When replacing the brake system, check the bearing and replace the oil seal.
first of all, it is important to find the location where the noise occurs. Automobile Hub Bearing There are many moving parts that may produce noise, or some rotating parts may come into contact with non rotating parts. If the noise in the bearing is confirmed, the bearing may be damaged and needs to be replaced.
leading to bearing failure on both sides of the front hub are similar, even if only one bearing is damaged, Automobile Hub Bearing it is recommended to replace it in pairs.
so it is necessary to adopt correct methods and appropriate tools in any case. During storage, transportation and installation, the components of the bearing shall not be damaged. Some bearings require high pressure, so special tools are required. Automobile Hub Bearing Be sure to refer to the automobile manufacturing instructions.
The entry of small particles into the bearing will also shorten the service life of the bearing. It is very important to maintain a clean environment when replacing bearings. Automobile Hub Bearing It is not allowed to knock the bearing with a hammer. Pay attention not to drop the bearing on the ground (or improper treatment). Check the condition of the shaft and bearing seat before installation. Even slight wear will lead to poor fit, resulting in early failure of the bearing.
do not attempt to disassemble the hub bearing or adjust the sealing ring of the hub unit, otherwise the sealing ring will be damaged and water or dust will enter. Automobile Hub Bearing Even the raceway of the sealing ring and inner ring are damaged, resulting in permanent failure of the bearing.
which can not be impacted, impacted or collided with other magnetic fields. Automobile Hub Bearing Take them out of the packing box before installation and keep them away from the magnetic field, such as the motor or electric tool used. When installing these bearings, observe the ABS alarm pin on the instrument panel through the road condition test to change the operation of the bearings.
in order to determine which side the thrust ring is installed, you can use a light and small thing * close to the edge of the bearing, and the magnetic force generated by the bearing will attract it. During installation, point one side with magnetic thrust ring inward and face the sensitive element of ABS. Note: incorrect installation may cause the function of the brake system to fail.
Other unsealed bearings, such as double row tapered roller bearings, must be lubricated with grease during installation. Due to the different sizes of the inner cavity of the bearing, it is difficult to determine how much grease to add. It is important to ensure that there is grease in the bearing. If there is too much grease, the excess grease will seep out when the bearing rotates. General experience: during installation, the total amount of grease shall account for 50% of the bearing clearance.
the torque varies greatly due to different bearing types and bearing seats. Please refer to relevant instructions.
