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.

摘要： A wheel bearing device having a unitized hub ring, double-row bearing and constant velocity universal joint with one of double-row inner raceways formed on the joint outer ring. An end portion of the joint outer ring is fitted to an outside periphery of the hub ring through serrated portions. The hub ring is plastically deformed and expanded from an inside diameter side toward an outside diameter side by pushing a steel ball into a through hole of the hub ring preventing play in the serrated portions by the diameter expansion. A surface-hardened layer is formed at least on a base portion of the wheel mounting flange.

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 sealing device for a bearing includes first and second annular sealing plates (1, 2) accommodated within an annular end space between inner and outer races (11, 12). Each of the first and second sealing plates (1, 2) is of a generally L-shaped section including a cylindrical (16, 26) wall and a radial upright wall (1a, 2a), and an elastic seal lip element (38). The first sealing plate (1) is secured with the radial upright wall (1a) thereof positioned adjacent respective end faces of the inner and outer races (11, 12), and the radial upright wall (1a) of the first sealing plate (1) has a free end remote from the cylindrical wall (1b) of the first sealing plate (1) spaced a predetermined distance from the cylindrical wall (2b) of the second sealing plate (2) to thereby form a radial gap (4). The radial upright wall (1a) of the first sealing plate (1) also has an outer side face (B) set back inwardly from a free end face (A) of the cylindrical wall (2b) of the second sealing plate (2).

摘要： A wheel bearing assembly is provided which has a rotating speed sensor unit which includes a seal for preventing entry of foreign matter and which takes up little space and thus can be mounted on the wheel bearing assembly without increasing the axial dimension of the fixed member of the wheel bearing assembly. The assembly includes a fixed member fixed to a vehicle body, and a rotary member rotatably supported in the stationary member through a bearing and mounted to a vehicle wheel. An annular sensor is fitted to a knuckle, which is a part of the fixed member, on the inboard side of the bearing. A sensor seal is fitted to the annular sensor and has a seal lip kept in slide contact with a seal land formed on a constant-velocity joint outer ring, which is a part of the rotary member, to define a sealed space on the inboard side of the bearing. An encoder is mounted on a bearing inner ring, which is a part of the rotary member, in the sealed space. The sensor element is disposed in the sealed space, opposite the encoder.

摘要： A wheel bearing device is proposed which maintains long life even under high-load, high-temperature conditions. On the surfaces of inner rings and tapered rollers of a multiple-row tapered roller bearing rotatably supporting a wheel, carburized, nitrided layers are formed which contain 0.80 wt % or more carbon and have a Rockwell hardness of 58 or over with the residual aaustenite content being 25-35 vol % to improve mechanical properties and fatigue characteristics of these parts and also keep the surface layers of these parts of suitable toughness, thereby improving the life of the wheel bearing device in a high-load, high-temperature environment. Also, an annular recess is formed in the inner periphery of the outer ring at a portion between the rows of the raceways.
