Ball bearing, especially for the core and throttle body in a fluid valve, has structured grooves for the separate balls to roll with reduced friction

摘要

The ball bearing assembly, for two components with a relative movement between them, has separate balls (1) within grooves (2) in circular arc or V-shapes formed by a ball miller around the core (3). The balls are magnetic or non-magnetic. The groove depths are set so that the balls range slightly over the outer edge of the throttle body and the balls act as the bearing for the throttle body.
