Tapered Roller Bearing Sealed Type

Sealed four-row tapered roller bearings belong to the technical field of bearings. The sealing ring is fixedly installed between the two inner rings, one part of the sealing ring is provided with a steel frame, the other part is a rubber lip structure. The sealing ring has a steel frame part and the inner ring A is an interference fit, and the rubber lip structure of the sealing ring is sealed with the side of the inner ring B. Its beneficial effects are: convenient installation, when the bearing inner ring is installed, the sealing rings are connected together and installed at the same time. The greater the pressure generated between the bearing and the roll, the tighter the sealing.
