ABSTRACT:
Systems and methods to achieve an auto-focus camera module having a precise bearing with low friction have been disclosed. Ball bearings are guiding a lens barrel. The balls of the ball bearings are running in guide slots and are held together by ball cages. Creeping of the balls is prevented by a positioning pin being deployed between a fixed part of a carrier of the camera module and a movable part of the lens barrel.
