A bearing roller chain having a seal mechanism preventing entry of foreign substance from the outside, and leaking of lubricating oil leakage to the outside and the like, thereby improving wear resistance of the bearing roller and reducing both the likelihood of rotation failure and the traveling resistance of the chain. The seal mechanism is provided between an inner link plate of the chain and the hollow bearing roller, which has a plurality of internal anti-friction rollers rotatable between the hollow bearing roller and a bush mounted between opposed inner link plates. The seal mechanism encloses the internal anti-friction rollers and comprises two parts, i.e a seal ring having an annular lip portion, which comes into close contact with an outer side surface of the bearing roller and an annular metallic seal member. The metallic seal member forms a labyrinth structure by providing a flange on an outer circumferential portion which loosely enters an annular concave groove in the outer side surface of the bearing roller. The seal mechanism provides a double sealing effect by virtue of the seal ring and the annular metallic seal member.
