ABSTRACT:
A high temperature furnace chamber includes a roller hearth for supporting and transporting workpieces to be heated. The rollers are supported at each end by a rotary sleeve having an inner diameter larger than the outer diameter of the rollers. Rotary movement of the sleeves transmits rotational forces to the rollers. Clearance provided between the rollers and the sleeves allows for roller dimensional variation during various furnace operating conditions.
