Tapered roller bearings are separated bearings, bearing inner and outer rings have tapered raceways, rollers for round table shape. Roller and raceway for line contact, can bear heavy radial and axial combined load, can also bear pure axial load. The larger the contact Angle, the higher the axial bearing capacity.The design of tapered roller should make the contact line of the roller and the inner and outer raceway extend and cross...

The composite radial load acting on the bearing ring is borne by the local area of the ring raceway and transmitted to the corresponding local area of the shaft or bearing seat. This load is called the fixed load. It is characterized by a composite radial load vector with absolute rest of the ring. Looser fitting can be used for the rings subjected to directional loads...

Under a certain load, the number of revolutions or hours experienced by the bearing before pitting is called the bearing life.The life of a rolling bearing is defined in revolutions (or hours of work at a certain speed) : the bearing within this life shall suffer initial fatigue damage (peeling or defect) on any bearing ring or rolling body. However, no matter in laboratory tests or in actual use...

Because bearings are now in the development of enterprises which have a more important role, no matter whether in the car assembly or in some transmission use of the work, the bearings will be as the main driving force to drive the normal operation of the device, so that it can effectively Improve production efficiency, in order to promote the efficiency of enterprise growth...
