Backing bearing

Backing bearings are rolling bearings featuring very thick outer rings. These bearings are installed onto stationary shafts as supporting rollers in group form. They are featured by simple geometrical shape and high radial load carrying capacity. Bus is used to grind the profile. The entire outer diameter surface can have optimal stress distribution, no matter whether it’s evenly distributed load or deflected load, which can also significantly improve and contact the geometrical accuracy. The smooth outer diameter contact surface has greatly improved the lubrication condition.
