Abstract
The roller assembly is utilized at the end of a turn in a turn chain assembly in a towveyor system. In the towveyor system a tow chain is guided and carried around the turn by a turn chain of the turn chain assembly. The roller assembly includes a non-rotatable stub shaft, a larger diameter, rotatable, hollow cylinder coaxial with the stub shaft, two axially spaced ball bearings rotatably mounting the cylinder on the shaft and a collar fixed on the cylinder for maintaining a tow chain at a desired height while it travels around the cylinder. A portion of the shaft extends axially beyond the cylinder for mounting the roller assembly in the turn chain assembly.
