Abstract: A cage for rolling elements of a high speed bearing. The cage includes a cage body made of a polymer material. The cage body includes a lubrication enhancer and/or an elastic modulus enhancer added to the polymer material during the manufacturing process. The lubrication enhancer makes the cage have a low friction coefficient, low heat generation and good wear resistance, and the cage has better stability when the bearing is under high temperature or high speed. The elastic modulus enhancer makes the cage have an excellent high elastic modulus, and the deformation of the cage is significantly reduced under the condition of high-speed operation of the bearing. These effects can be obtained by adding both the lubrication enhancer and the elastic modulus enhancer at the same time, which makes the cage more suitable for high-speed bearings.
