Spherical roller bearing can be very good with the use is very important, can make the spherical roller bearing in the stationary ring and rotating ring are respectively installed and parts of the stationary part (usually bearing) and rotating part (usually axis) with consolidation, in order to achieve rotation state of load transfer and limited movement relative to the system the basic task of the stationary position. But there is also a compatible material factor that will affect the friction of the bearing, so that the bearing can not be used normally.
The main factors affecting the friction compatibility of spherical roller bearing are the following six points:
(1) it is difficult to make an alloy as a secondary material.
(2) the affinity of materials and lubricants.
(3) the friction factor of the sub material in the non lubricated state.
(4) the microstructure of the material.
(5) the thermal conductivity of the material.
(6) the size of the surface energy of the material and the properties of the oxide film.
