High -temperature resistant deep groove ball bearing

The utility model belongs to the technical field of machinery, in particular to high -temperature resistant deep groove ball bearing. This high -temperature resistant deep groove ball bearing includes body, its characterized in that: the body is by interior inner circle, graphite holder and outer lane of being in the same place for nested within each other in proper order outside to, and the lower extreme evenly is equipped with a plurality of cradle on the graphite holder, and the cradle bottom be spherical, and upper portion is the toper, and the tapering is 8~20 degrees, and the inner circle has two, is equipped with the 0.1 big~0.5mm of channel diameter of groove, the fore shaft diameter ratio inner circle of groove on one side of the flange of one of them inner circle. When the graphite holder operates at the bearing graphite powder drop have good in lubrication action, high temperature resistant and lubricated effectual, outer lane integral type structure, few, the light in weight of occupation space, t
