A seal arrangement for a wheel bearing having first bearing part and a second bearing part integrally connected to a wheel bearing flange, between which bearing parts rolling elements are guided. The sealing arrangement includes: a carrier element, which is connected to the first bearing part and an elastic element is provided on the carrier element. The elastic element has at least one sealing lip, and the carrier element has a fastening section, which is connected to the first bearing part. A stop part is fastened to the second bearing part with which the at least one sealing lip is in rubbing contact. The wheel bearing flange has an axial projection at least partially surrounds an axial projection of the first bearing part, and an inner surface of the axial projection of the wheel bearing flange forms a seat for the stop part.

A rolling bearing for rotatably supporting a shaft has an inner ring with a first raceway for a rolling body, an outer ring with a second raceway for a rolling body, and rolling bodies which are arranged between the raceways of the bearing rings. At least two plates are fastened to a first of the bearing rings, wherein an electrically conducting element is arranged between the two plates, which electrically conducting element lies against the respective other bearing ring or a component which is connected to the respective other bearing ring.

A greasable bearing assembly may include an outer ring, an inner ring disposed within, and concentric with, the outer ring, and a plurality of balls disposed between the outer ring and the inner ring. A greasable seal may be disposed adjacent the outer ring and the inner ring, the greasable seal further comprising a toroidal shape comprising an outer face and an inner face. An outer ring-shaped surface may extend from the outer face to the inner face. An inner ring-shaped surface may extends from the outer face to the inner face. An intake opening may be disposed through the greasable seal and extend from the outer ring-shaped surface to the inner face. A securing member may be formed as a lip at the inner face to mateably couple between the inner ring and the outer ring.

A bearing assembly comprises an inner ring comprising an inner ring raceway, an outer ring comprising an outer ring raceway, rolling elements configured to roll or rotate between the inner ring raceway and the outer ring raceway, at least one electrically conductive part with a first end and a second end, and a seal coupled to the at least one electrically conductive part. The seal is configured to directly contact only one of the inner ring or the outer ring. The first end is configured to electrically contact one of the inner ring and the outer ring and the second end is configured to electrically contact the other of the inner ring and the outer ring.

A cam follower assembly includes a ball bearing having an outer ring and an inner assembly which includes two or more segments. The inner assembly is disposed in the outer ring with a full complement of balls disposed therebetween. The outer ring and inner assembly each include a race having a gothic arch cross sectional configuration that causes the balls to roll on two portions of each race.

A bearing system for a rotating vertical shaft includes a first ball bearing, having a first pitch diameter and a first axial stiffness and a second ball bearing having a second pitch diameter and a second axial stiffness. The first ball bearing is a deep groove Conrad bearing. The second ball bearing is an angular contact bearing. The first and second ball bearings are coaxial, secured to one another and rotatable together. The first pitch diameter is at least 1.5 times greater than the second pitch diameter. The bearing system has an axial stiffness ratio defined by the first axial stiffness divided by the second axial stiffness. The axial stiffness ratio is based on an axial preload force applied to the second outer ring such that an operating torque of the bearing system is within a predetermined range at temperatures from minus 40 to positive 85 degrees Celsius.

A dental handpiece (1) having a drive (3) of a tool (4), which drive is located in a head housing (2), has at least one media-conducting line arranged in the head housing, which media-conducting line has an outlet opening to the tool, and a tool receptacle (16) arranged in a drive chamber, which tool receptacle is rotatably supported by means of a rolling bearing (11) in a support (14) of the head housing (2) on a side of the drive chamber facing the tool. The rolling bearing has an outer race (13), which is supported against the head housing (2) radially in the support (14) in the area of a raceway (22) and which has a sub-area (21), the outside diameter D2 of which is reduced compared to the outside diameter D1 in the area of the raceway (22). The head housing has a housing projection (23), which extends into the area of the reduced outside diameter D2, and the media-conducting line (17) runs at least partially through said housing projection (23).

A bearing sealing device includes two seals (inner and outer seals) sealing the space between the inner and outer races of a bearing to ensure higher seal performance, and also to reduce the area of the inner periphery of the outer race that needs to be ground. The bearing sealing device includes a ring constituted by a metal annulus, and a rubber part. The metal annulus is formed by cold pressing, and has a seal contact surface kept in contact with seal lips of the outer seal. The rubber part includes a press-fitted portion fixed to the inner periphery of the outer race. The inner race has, on its outer periphery, a cylindrical fitting surface to which the outer seal is press-fitted.

A rolling bearing assembly has a first ring including a first race, a second ring including a second race, and a plurality of rolling elements in rolling contact with the first and second races. The rolling bearing assembly also has a sealing assembly including a first end in contact with the first ring and a second end in contact with the second ring. The sealing assembly has a shield, a sealing element, and a grounding element. The grounding element and the shield combine to provide an electrically conductive path between the first ring and the second ring. The grounding element and the sealing element combine to seal between the first ring and the second ring.
