Abstract
A bearing assembly for use in a medical, surgical, or dental handpiece that enables spindle rotation for a supported rotary tool at high speeds. The bearing assembly incorporates annular gap shields at each axial end to prevent contaminate ingress and to retain lubricating grease within the bearing assembly to avoid re-lubrication after each use or sterilization cycle.
