摘要： A wheel support bearing assembly includes inner and outer members (1 and 2) and at least one row of rolling elements (3) operatively interposed between the inner and outer members (1 and 2) and an annular sealing device (5) sealing an open end of an annular space defined between the inner and outer members (1 and 2). The sealing device (5) includes first and second annular sealing plates (11 and 12) fitted to different members out of the inner and outer members (1 and 2). Each of the first and second sealing plates (11 and 12) includes a generally cylindrical wall (11a or 12a) and a radial wall (11b or 12b) assembled together to represent a generally L-shaped section. The first sealing plate (11) is fitted to one of the inner and outer members (1 and 2) that serves as a rotating member. An elastic member (14) mixed with a powdered magnetic material is bonded by vulcanization to the radial wall (11b) of the first sealing plate (11). A protective cover (18) made of a non-magnetic material is positioned on one side adjacent an exterior of the multi-pole magnet (14) with a predetermined air gap left therebetween that the number of revolution can be detected through the protective cover (18).

摘要： A wheel bearing includes a sealing device 5 positioned between inner and outer members 1 and 2. This sealing device 5 includes an elastic member 14, which eventually forms an encoder grid and is provided on a first annular sealing plate 11. A second annular sealing plate 12 is provided with sealing lips 16a to 16c. An engagement 18 between a cylindrical wall 11a of the first annular sealing plate 11 and the inner member 1 is provided with an elastic member 20 made of a material dissimilar to that for the elastic material 14. This elastic member 20 may be a rubber coated layer, resin paint layer, a thin film of adhesive material or a ring-shaped rubber member. Thereby, any possible ingress of water across an engagement surface of the annular sealing plate is prevented, accompanied by increase of the lifetime of the bearing, with no problem associated with separation and displacement of the annular sealing plates. The magnetic flux density can also be easily secured.
