    摘要： A seal for a bearing (100) includes an annular retaining ring (12) defining a first radially innermost portion (12A) and a first radially outer end (12C); and a resilient ring (14) defining a second radially innermost portion (14A) and a second radially outer end (14C). The first radially innermost portion and the second radially innermost portion are aligned with one another and together define a securing root of the seal. The root is adapted to seat in a groove (22) of an inner ring of the bearing. The resilient ring projects radially outward from the annular retaining ring. The resilient ring is more flexible than the annular retaining ring. The second radially outer end defines a sealing surface adapted to slidingly engage an inner bearing surface of an outer ring of the bearing. The first radially outer end of the retaining ring terminates between the first radially innermost portion and the second radially outer end of the resilient ring.

    摘要： A rolling bearing includes, at an end of a sealing member body (8), a sealing lip portion (9) having a radial edge (9a) that is brought into radial contact with an inner ring (1). The sealing lip portion (9) has a fishhook-shaped cross-section in which the sealing lip portion (9) is bent at a waist portion (11) that is an intermediate portion thereof in a radial direction, so as to form a relief recess (13) in a surface on an outer side relative to a bearing space and an extensive portion (9b) extends, in a turned back manner, from the radial edge (9a) so as to be inclined relative to an axial direction toward the outer side of the bearing. The sealing lip portion (9) includes a projection (12) that has a tapered shape in which a portion that is closer to a tip end side than the waist portion (11) has a dimension reduced toward a tip end side, and a thickness (t1) of the waist portion (11) is set so as to be not smaller than 25% of a thickness (t2) of the tip end of the sealing member body (8), and not greater than 75% thereof.

    摘要： A seal lip portion 9 includes a lip main body (9a) and a projecting section (16) protruding from a peripheral edge of the lip main body (9a) and slidingly engageable with an inner ring (1), and this projecting section (16) is made of a highly frictionally wearable material which allows the projecting section (16), when frictionally worn, to establish a non-contact or a light contact to such an extend as to result in a contact pressure that can be regarded as zero. A fitting section (13) fitted into a seal mounting groove (2b) in a seal member main body (8) is held in a drag-rotation preventive structure that prevents circumferential movement due to a drag-rotation relative to an outer ring (2).

    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.
