摘要： A seal assembly for sealing a grease lubricated large rolling-element bearing includes a radial shaft seal having at least one seal lip configured to sealingly abut against a shaft to seal a bearing interior and substantially prevent a grease discharge from the bearing and a grease flow regulation device, such as an annular pumping ring, for regulating a grease pressure at the at least one seal lip, the grease flow regulation device being mounted adjacent to the radial shaft seal at a side of the radial shaft seal that is intended to face the bearing interior in an installed state.

摘要： A bearing assembly includes an inner ring and an outer ring that define a bearing interior between them and either the inner ring or the outer ring is fixed. When the inner ring is fixed, the inner ring includes at least one substantially radial through opening and when the outer ring is fixed, the outer ring includes at least one substantially axial and/or radial through opening, or at least one substantially axial and/or radial through opening is provided on a ring fixedly connected to the outer ring. The through opening is disposed between a 9 o'clock position and a 3 o'clock position on the inner ring when the inner ring is fixed or on the outer ring when the outer ring is fixed.

摘要： A bearing assembly includes first and second rolling-element bearings each having first and second bearing rings, a raceway and a flange element at both ends of the raceways. Two of the flange elements are formed on a common flange body, and the flange body is axially pressed onto cylindrical mounting surfaces of the first bearing rings of the first and second rolling-element bearings and held in place by a press fit.

摘要： A rolling-element bearing includes inner and outer rings and a cage between the rings, the cage having a plurality of cage segments with lateral boundary walls defining a receiving pocket for a rolling element having a diameter Dw, the pockets being dimensioned such that in a load-free state the rolling elements are positionable in the receiving pockets with a circumferential clearance (c) on the pitch circle between adjacent boundary walls of the pocket such that the clearance satisfies the relationship: cmax≧c≧Cmin, where: cmin=0.01*Dw−0.5 mm and cmax=0.02*Dw−0.4 mm, and wherein the diameter (Dw) of the rolling-element bearing is at least 50 mm.

摘要： The rolling bearing comprises an inner ring 1, an outer ring 2, at least one row of rolling elements and at least one seal 7 provided between the outer and inner rings. The seal 7 has, in cross section, the overall shape of an H and comprises internal lips 21, 22 and external lips 23, 24 forming the two substantially parallel branches of the H. The inner and outer rings 1, 2 comprise opposite radial ribs 25, 26 located axially between the internal and external lips 21 to 24 to axially retain the seal.
