  • Patent number: 8419289
    Abstract: A radial bearing configured as a single-row spherical roller bearing is provided that includes an inner and outer bearing ring, and rollers arranged between the bearing rings. The rollers have two side faces which are flattened symmetrically from a spherical base shape, and roll in two groove-shaped raceways which are defined by two axial rims. The width of the rollers between their side faces is at least 70% of the diameter of the spherical base shape and is greater than the distance between the axial rims. The rollers are in full linear contact with their running faces in the bearing rings at an operational pressure angle of up to 25° on both sides of the bearing longitudinal axis. The distance between radially opposite axial rims when the bearing rings are arranged eccentrically to each other is less than the diameter of the spherical base shape of the rollers.

  • Patent number: 8047723
    Abstract: A radial anti friction bearing (1) which is configured as a single-row spherical roller bearing, which includes an outer bearing ring (2), an inner bearing ring (3) and a plurality of spherical rollers (5) that are arranged between the bearing rings (2, 3). The spherical rollers have respectively two side faces (6, 7) which are flattened symmetrically from a spherical base shape, are retained with uniform spacing to each other a bearing cage (4) and roll with their running faces (8) in two groove-shaped raceways (11, 12) which are defined, respectively, by two axial rims (13, 14 and 15, 16). The width (bK) of the spherical rollers (5) between their side faces (6, 7) is smaller than the distance (aB) between the radially opposing axial rims (13, 15 and 14, 16), such that the spherical rollers (5) can be in the space therebetween via the axial mounting method in the radial anti friction bearing.

  • Patent number: 8007185
    Abstract: The radial rolling bearing has an outer bearing ring, an inner bearing ring, and spherical rollers arranged between bearing rings. The spherical rollers have two flat side faces arranged parallel to one another. The spherical rollers are retained with uniform spacing to one another in the peripheral direction by a bearing cage. The spherical rollers have a width between their side faces of approximately 70% of the diameter of their spherical basic shape. The running faces of the rollers roll in two groove-shaped raceways which are formed in the inner side of the outer bearing ring and in the outer side of the inner bearing ring. At least one of the axial rims which delimit the groove-shaped raceways is reduced in radial height such that the radial bearing can be equipped with an increased number of spherical rollers in an axial assembly process.

  • Patent number: 7938585
    Abstract: A radial antifriction bearing which has an outer bearing ring, an inner bearing ring and a multitude of rollers, arranged between the bearing rings and held by a bearing cage. The rollers are configured as spherical disks that each have two parallel lateral surfaces which are symmetrically flattened from a basic spherical shape. The bearing cage has cage pockets in which the rollers are axially guided between the bearing rings via two low-friction point contacts between the center areas of their lateral surfaces and the longitudinal webs of the cage pockets. The rollers have a defined degree of freedom for tilt movements exerted at an angle to the running direction and a defined degree of freedom for self-adjustment to the pressure angle of the radial antifriction bearing.

  • Patent number: 7600614
    Abstract: An assembly comprised of a brake disk with a hub. Webs which are adjacent to one another in the circumferential direction extend between and are anchored to the brake disk and are attached to the hub.

  • Patent number: 7147375
    Abstract: A linear guide for transmitting a torque between a tubular housing, which is defined by a longitudinal axis and rotatable about the longitudinal axis, and a shaft, which is received in the housing and movable in the direction of the axis in relation to the housing, includes a bearing assembly received in the housing for support of the shaft and attached to the housing by swaging a housing portion. The bearing assembly has two bearing members and a set of rolling bodies disposed between the bearing members. One bearing member is constructed as bushing which is retained in the housing and defines a center axis which is oriented out-of-alignment with a normal upon a longitudinal shaft axis, and the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft.
