An abrasion-resistant and heat-resistant conveyor chain is provided to improve durability by controlling abrasion extension of a chain due to uneven abrasion between an inner circumference surface of a roller and an outer circumference surface of a bush. An abrasion-resistant and heat-resistant conveyor chain(100) comprises a pair of inner plates(110) separately arranged on left and right sides, a bush(120) fitted to a bush hole(111) of the inner plate, a heat-resistant roller(130) inserted from outside to rotate the bush, a connection pin(140) rotatably fitted inside the bush, a pair of outer plates(150) separately arranged on left and right sides, which connect the inner plates in a chain length direction and a sleeve shaped spacer(160) fitted to an inner circumference surface of the heat-resistant roller, which is concentrically arranged between the heat-resistant roller and the bush.
