Deep groove ball bearings are the most widely used type of rolling bearing. Its characteristics are small friction resistance, high speed, can be used to bear radial load or radial and axial at the same time the role of the combined load on the machine, can also be used to bear axial load on the machine, such as small power motors, cars and tractors gearboxes, machine tool gearboxes, general machines, tools, etc.
Tapered roller bearings belong to the separation bearing, bearing the inner and outer ring have tapered raceway. The bearings are divided into single, double and four row tapered roller bearings and other different structure types according to the number of rollers installed. Single row tapered roller bearings can bear radial load and single direction axial load
The main role of the wheel bearing is to carry the weight and provide precise guidance for the rotation of the hub, it is subject to both axial and radial loads.
Grease can be added first when sealing the bearing, omitting the outer hub seal and maintenance-free, etc., and has been widely used in cars.There is also a trend of gradually expanding applications on trucks.
