A Y-type double-lip non-contact rubber skeleton seal ring for deep groove ball bearings belongs to the field of bearing manufacturing technology. The feature lies in that it comprises a sealing ring body and a rib plate skeleton. A ring-shaped rib plate skeleton is provided on the inner side of the sealing ring body. The outer peripheral ring of the sealing ring body is provided with an outer lip, and the inner peripheral ring of the sealing ring is provided with an inner lip. The cross-section of the inner lip is in the shape of a "Y". The utility model has made a brand-new design for the sealing ring between the inner and outer rings of the bearing. By improving the double-lip sealing structure and combining it with elastic soft points, a relatively closed grease storage cavity has been achieved. Meanwhile, during the entire operation of the bearing, a single connection arm with the sealing ring body is connected by elastic soft points, which can to a certain extent meet the extreme deformation conditions Under such circumstances, the bearing can still operate smoothly and at high speed. While ensuring the flexible rotation of the bearing, the sealing property of the bearing grease is significantly improved and enhanced, thereby achieving the technical effect of no grease leakage.
