Bearing ring phosphating device

The utility model belongs to the technical field of bearing production, and particularly relates to a bearing ring phosphating device which comprises a phosphating box, a spraying mechanism and a rotating mechanism, a placing opening is formed in the top of the phosphating box, and an observation window is fixedly installed on the front face of the phosphating box. According to the bearing ring phosphating device, in the spraying process, a bearing ring can continuously rotate, phosphating liquid can be evenly sprayed to the outer surface of the bearing ring, before the phosphating liquid is sprayed to the bearing ring, a layer of coating solution can be sprayed to the outer surface of the bearing ring, and resin synthesized through ethylene polymerization reaction is sprayed to the outer surface of the bearing ring; the surface roughness and the contour shape of the bearing ring can be leveled, it is guaranteed that the roughness and the contour shape of the bearing ring meet the spraying precision requireme
