摘要： A wear resistant, heat resistant conveyor chain comprising a series of links, each having a heat resistant roller rotatably fitted onto a bush between inner plates. The links are interconnected in the longitudinal direction of the chain by outer plates, and connecting pins rotatably inserted into the bush. A wear resistant, heat resistant sleeve-shaped spacer protrudes beyond the end surfaces of the heat resistant rollers toward the right and left inner plates to eliminate any sliding contact between the end surface of the heat resistant roller and the inner side surface of the inner plate.
