Conveyor rolls used in high temperature applications, and an end cap assembly for such rolls. The conveyor roll comprises a ceramic spool, an end cap and a tolerance ring. The end cap contains a metal ferrule and has an internal circumference adapted to fit over an end of the ceramic spool. A tolerance ring is interposed between each end of the ceramic spool and the end cap. The tolerance ring is composed of resilient metal having a plurality of circumferentially arranged corrugations. The conveyor roll can resist temporary overheating or blockage without damage.
