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 supporting structure and is located at an upper end of the housing. To simplify installation and removal of the unit in the supporting structure, the outer periphery of the second holding device is larger than that of the housing and locking elements are provided to fix the unit in the supporting structure. In addition, the second holding device is constructed so that after release of the locking elements it can be removed from the supporting structure as an independent element, thus allowing the housing with the components it contains to be removed from the opening in the supporting structure.

Abstract

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 supporting structure and is located at an upper end of the housing. To simplify installation and removal of the unit in the supporting structure, the outer periphery of the second holding device is larger than that of the housing and locking elements are provided to fix the unit in the supporting structure. In addition, the second holding device is constructed so that after release of the locking elements it can be removed from the supporting structure as an independent element, thus allowing the housing with the components it contains to be removed from the opening in the supporting structure.
