Factory Cheap Transmission Conveyor Motorcycle/Timing /Bicycle Link Chain Roller Chain

The roller is looped on the sleeve. When working, the roller rolls along the sprocket tooth profile, which can reduce the wear of the gear teeth. The main wear of the chain occurs on the contact surface of the pin shaft and sleeve. Therefore, there should be a little gap between the inner and outer chain plates so that the lubricating oil can penetrate between the friction surfaces. The chain plate is generally made into an "8" shape, so that its cross sections have nearly equal tensile strength, and also reduce the mass of the chain and the inertia force during movement.

All parts of the chain are made of carbon steel or alloy steel and heat treated to improve strength, wear resistance and impact resistance. Roller chains can be made into single-row chains and multi-row chains. When transmitting large power, double-row chains or multi-row chains can be used. The bearing capacity of multi-row chain is proportional to the number of rows. However, due to the influence of precision, the load borne by side-by-side chain is not easy to be uniform, so the number of rows should not be too large.
