ABSTRACT:
An improved bearing mechanism works in conjunction with the control rod of a vertical blind system or a roller shade system to provide superior bearing and load handling capability. A conical bore has a plurality of grooves into the surface of the conical bore. A series of cylindrical rollers are supported within the grooves, and against a central rotational member having a conical surface for bearing against the rollers. A set screw is used to control the seating of the central rotational member within the conical bore, is used to make up any tolerance created through the manufacturing process, and can be used to increase the tension necessary to hold a roller shade in place.
