Abstract
A composite idler roller has an integral internal bearing surface which interfits with the outer or tread portion of the roller. Flange seals or internal lubricant retaining grooves may be incorporated in the bearing surface. The outer or tread portion of the roller is inserted in a mold concentric with a core pin. The bearing material is injected into the space between the outer portion and the core pin. The centering of the outer portion may be by external contact with the mold or internal shoulder contact with the core pin. The core pin may be wholly or partly collapsible. The roller may have a wide variety of tread styles and may be stud or yoke mounted. In another form, the entire roller is formed of the bearing material.
