摘要： A swivel joint includes a tail section and a body portion that define a passageway therethrough and which can rotate relative to one another. One or more seals and bearings can be disposed between the tail section and the body portion. An electrical conductivity grease fitting can be mounted within a bore hole in the body portion. The electrical conductivity grease fitting can have a lubricant passed therethrough to lubricate the bearings. The electrical conductivity grease fitting has a first portion in electrical communication with the body portion and a second portion that is biased into electrical communication with the tail section to maintain electrical conductivity between the tail section and the body portion.

摘要： A wheel bearing apparatus has a double row angular contact ball bearing. A height of a shoulder of a shoulder portion (18) of an outer member (12) with respect to a ball diameter of a double ball (14) row is set in a range of 0.35 to 0.50 mm. A corner (19) of the shoulder portion (18) has a relief surface (19a) and a chamfered portion (19b). The relief surface is on a straight line that is on a tangent line of an outer raceway surface (12a). The chamfered portion (19b) is round in a circular arc with a predetermined radius of curvature r. The corner (19) is formed simultaneously by a formed grinding wheel forming the double row outer raceway surface (12a). The corner is formed smoothly continuous from each outer raceway surface (12a). A length in the radial direction of the relief surface (19a) is set greater than or equal to 0.2 mm.

摘要： A slinger has a substantially L-shaped cross-section and includes a rotating cylindrical portion and a rotating circular ring portion. An inner circumferential surface of the rotating cylindrical portion is a stepped cylindrical surface in which a large-diameter portion formed at a portion close to the rotating circular ring portion and a small-diameter portion formed in the remainder are continuously connected by a stepped portion. The encoder supported by the rotating circular ring portion is formed by solidifying and securing a molten permanent magnet material in a state that a molding die collides with the stepped portion. An outer diameter of a hub is defined as φD, an inner diameter of the small-diameter portion in a free state is defined as φd1, and an inner diameter of the encoder in a free state is defined as φd2, a relationship of φd1≦φd2
