摘要： A rolling contact bearing assembly includes a seal member having a seal lip segment. The seal lip segment includes a waist portion having, as viewed in a cross section, a bent V-shape such that a surface of the seal lip segment on outer side defines a relief recess and also includes a protrusion portion distal to the waist portion and having a tapered shape narrowing towards a free end thereof. The seal member installed in the bearing assembly applies urging force on one of inner and outer raceway rings, against change in degree of interference of the protrusion portion with the raceway ring. The protrusion portion includes such high wear material that rotation of the bearing assembly results in wear of the protrusion portion to cause the protrusion portion to make non-contact status or light contact status of a contact pressure of substantially zero.
