Abstract: The invention relates to a rolling bearing arrangement with: a housing (10), a shaft (20), a first rolling bearing and a second rolling bearing for rotatably supporting the shaft in the housing, wherein the first rolling bearing is designed as a fixed bearing in which an outer ring (32) of the first rolling bearing is positionally fixed in the housing and an inner ring (34) of the first rolling bearing is rigidly connected to the shaft, wherein the second rolling bearing is designed as a floating bearing in which the outer ring (42) of the second rolling bearing is arranged axially displaceably in the housing and the inner ring (44) of the second rolling bearing is connected axially displaceably to the shaft, and wherein both the outer ring (42) and the inner ring (44) of the second rolling bearing are each pressed in the axial direction towards the first rolling bearing by a pre-tensioning means in order to prevent a rotation of the outer ring (42) relative to the housing and a rotation of the inner ring (44

Abstract: A ball bearing cage includes a plurality of ball pockets, wherein each ball pocket serves for receiving a ball, wherein each ball pocket (12, 22) has a width (B) in axial direction of the ball bearing cage (10, 20) and a length in circumferential direction of the ball bearing cage (10, 20), with the width (B) being slightly greater than a diameter of the ball (30), wherein the length is greater than the width (B) of the ball pocket (12,22) at least at an outer circumference (UA) of the ball bearing cage (10), and the length (LA) of the ball pocket (12,22) at the outer circumference (UA) of the ball bearing cage (10) is greater than the length (LI) of the ball pocket (12,22) at the inner circumference (UI) of the ball bearing cage (10,20).

Abstract: The present invention relates to a cage for a rolling bearing, in particular for a ball bearing, to a rolling bearing with a cage and to the use of a cage in a high-speed rolling bearing with a characteristic speed value n×dm>1,000,000 mm/min, in particular for industrial spindle-bearing applications and in the medical sector, in particular in dental technology.
