Abstract:
A seal for a rolling bearing includes a core metal and an elastic member configured to cover the core metal. A fitting portion is fixed to an outer ring and a seal portion contacts an inner ring. In the outer side of the seal portion an auxiliary lip projects without contacting the inner ring and in the inner side a main lip projects contacting the inner ring. An annular groove is formed between the main lip and a thick wall portion thus forming a flexible portion having a small wall thickness at a root portion of the main lip. The auxiliary lip inhibits intrusion of foreign substances and moisture, reduces external pressure acting on the main lip and ensures the sealing performance of the main lip. The flexible portion reduces the sliding resistance of the main lip.

Claim (Index 1):
An annular seal for a rolling bearing having an inner ring and an outer ring, wherein the seal is to be fixed to the outer ring for sealing a space defined between the inner ring and the outer ring, the seal comprising:\n an annular core metal extending between the inner ring and the outer ring; and an elastic member configured to cover at least a portion of the core metal, wherein the elastic member includes a seal portion configured to cover an inner surface and an outer surface of an inner peripheral portion of the core metal in an axial direction of the rolling bearing, the seal portion includes a thick wall portion configured to cover the inner surface of the core metal, the thick wall portion being thicker than a portion of the seal portion covering the outer surface of the core metal, an auxiliary lip and a main lip are formed in an inner peripheral portion of the seal portion, wherein the auxiliary lip is in a non-contact state in relation to an outer peripheral surface of the inner ring with a gap between the auxiliary lip and the outer peripheral surface, the main lip is formed at an axially inner side of the auxiliary lip and the main lip contacts the outer peripheral surface of the inner ring, and an annular groove opening toward the inner side in the axial direction is formed between the thick wall portion and the main lip of the seal portion thus forming a flexible portion having a small wall thickness at a root portion of the main lip.
