Super Precision High Speed Angular Contact Ball Bearings are designed for rigid, high speed, high tolerance applications. Spindle bearings used in pairs arrangemet can support axial forces on both directions and moments. Bearings in a tandem arrangement can only support axial loads in one direction. Spindle bearings are available with a 15 degree or 25, 30 degreee contact angle. Various cage options are available as well as the use of ceramic balls which allow for higher speed.

A high speed spindle that will be used in a metal cutting machine tool must be designed to provide the required performance features. The major performance features include:Desired Spindle Power, Peak and Continuous,Maximum Spindle Load, Axial and Radial,Maximum Spindle,Speed Allowed,Tooling Style, Size and Capacity for ATC,Belt Driven or Integral Motor-Spindle Design

Although these criteria may seem obvious, for the spindle designer, they represent a wide array of needs that are quite difficult to meet and optimize, in one design. As we will discover, many of the criteria are contradictory to one another, and eventually a compromise must be chosen to provide the best design.
