The annular rubber sleeve is internally provided with the annular spring, so that the sealing performance is better.

Preferably, the ring grooves contain lubricating oil. The lubricating oil is stored for long time lubrication without frequent oiling.

Preferably, a through groove is arranged between two adjacent ring grooves. The lubrication between the roller and the chain shaft is kept uniform.

The utility model has the advantages that: set up the oil reservoir between roller and the chain axle, set up the annular in the roller, the annular reduces the roller and rubs when rotating, stores lubricating oil in the annular and lasts for a long time again and refuels for the chain, and this kind of design has reached the effect that does not need often to refuel when using the chain.
