Fafnir® Spindle Angular Contact Ball Bearings (9300WI, 9100WI, 200WI, 300WI)
Spindle bearings are a special design of the single row angular contact ball bearings; they were developed primarily for high-speed work spindles of machine tools. The spindle bearings differ from the angular contact ball bearings by the contact angle, the degree of accuracy, and the type of cage.Angular contact ball bearings The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.
Ball screw support bearings are designed to provide maximum axial rigidity and improved feeding accuracy for use with precision ball screws. They are high accuracy angular contact thrust bearings which are superior to combinations of standard angular contact bearings or arrangements of radial and thrust bearings for ball screw applications.
