Abstract
A ball bearing type roller cylinder assembly is disclosed comprising a center shaft having a free end. The shaft may, for example, be held in a mounting fixture. A spindle concentric with the center shaft is fixed on its free end. A roller cylinder housing the spindle comprises a cylindrical outer skirt, a first end cap which cooperates with a first end surface of the spindle to form a first ball bearing race, and a second end cap which cooperates with the second end of the spindle to form a second ball bearing race. The roller cylinder is freely rotatable and contacts the spindle only indirectly through the ball bearings. Preferred emobodiments of the roller cylinder assembly are suitable for use alone or in sets in high temperature applications, particularly in glass fabrication systems for hot press forming heated sheets of glass.
