Gearbox mountings

Gearbox bearings in many types, mainly by gearbox gear oil lubrication. More metal particles in lubricating the bearing life is greatly shortened, therefore required to adopt a special heat treatment process, so there raceway surface compressive stress, reduce particulate impurities raceway on the degree of sensitivity, improved bearing life. At the same time according to the working conditions of the bearing, the bearing slewing ring further optimized design, improved bearing processing method, and further improve bearing performance.
