cages
The most common bearing cages are shown below. In some cases, such as high-load applications, a full complement design may be the best choice. For operating speed, please refer to the Nmax/fn values in the product tables (see catalog) and the multiplier table. NHBB can also supply specially designed cages to meet your specific requirements. If you are in any doubt, contact NHBB for optimum cage selection.
