초록

A conveyor ball unit comprises a conveyor ball mounted on a plurality of mounting balls in a mounting shell. A spring arrangement is provided to support the mounting shell resiliently in a housing and the conveyor ball is retained on the mounting balls by a retaining ring. A first holding device is provided to keep the housing substantially perpendicular to the surface of a supporting structure for the conveyor ball unit against a force acting on the conveyor ball. A second holding device is provided to hold the housing within an opening defined in the s...
