Bearings are able to separate, easy to use

Tapered roller bearings can be separated from the roller, the inner ring, cage assembly consisting of the outer ring can be installed separately. And roller and raceway contact at the contact line allows to reduce stress concentration. Tapered roller bearings can bear large axial load and radial load. Because of tapered roller bearings can only pass one-way axial load, so, in order to be able to pass in the opposite direction of axial load, you will need to install a tapered roller bearings.
Tapered roller slewing bearing are used in the most is the amount of single row tapered roller bearings. Now the car's front wheels, the most recent small size of the double row tapered roller wheel bearing are used on. And four-row tapered roller bearings used in large-scale cold rolling mill and other heavy machines.
Improved bearing material smelting technology to improve the uniformity of steel
Improved bearing material smelting technology to improve the uniformity of steel
Compared with the industrialized countries, the oxygen content of bearing steel has been close though foreign advanced level, but the carbide size, inclusions, distribution uniformity and composition uniformity compared to the gap with foreign countries is still very large, such as said large size of the inclusions and carbides are more, because the basic ingredients resulting in uneven formation of black and white areas, so that the bearing part quality, but off a serious impact on bearing life, reliability and consistency.
Furthermore, the rolling contact surface of the large size of the presence of inclusions, the surface accuracy is severely degraded, the bearing noise increases. Therefore, the bearing industry and metallurgical industry must negotiate, promoting nearly metallurgical industry in reducing the oxygen content, based on the rolling technology, casting solidification technology, inclusions control and testing technology research carried out together, such as improved when casting electromagnetic stirring, to increase the size of the slab, to enhance high-temperature diffusion annealing, etc., to improve carbide inclusions and the uniformity of size and distribution.
