37x68x34mm Mr410569 Rear Wheel Bearing

      Wheel bearings and bearing primary role is to provide accurate wheel rotation guide, both axial load and radial load, is a very important component. Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearing combination, bearing installation, oiled, sealed and adjust clearance are carried out in the car on the production line. This structure makes it difficult in the automotive assembly plants, high costs, poor reliability, maintenance and car maintenance, but also the need for bearing cleaning, oiling and adjustment. Developed on the basis hub bearing unit is the standard angular contact ball bearings and tapered roller bearings on, it will be two sets of bearings as a whole, has assembled a good performance, can be omitted clearance adjustment, light weight, compact, load capacity large, sealed bearings can be pre-loaded into the grease, of the hub seals and maintenance, etc. are omitted from the outside, is already widely used in cars, in the truck also has a tendency to gradually expand the application. 

      In the process of maintenance, often find some cars have bigger noise, check tire no abnormal wear and tear, no sound in the lifting machine rotating wheels.This phenomenon is often caused by wheel hub bearing abnormal damage, abnormal refers to the bearing damage due to installation.Car front wheel bearings are generally double row ball bearing, if you use the hammer knock when install the bearing installation, or when the bearing is installed into the bearing installation, by means of the pressure bearing inner ring can cause side bearing raceway damage.When the vehicle noise, and when the wheel off the ground because of race a better side, so can't hear the noise significantly.The correct installation operation is the key to long bearing life.
