Normal chain wear is often the result of friction between the rivet and the ID of the barrel. Sprocket size and pitch angle will determine the relative motion between parts, and the degree of wear.
Lubrication of these surfaces would reduce wear and slow the process of corrosion.
Since lubrication significantly reduces the amount of wear to the chain, it would seem to be good economics to pre-lube the chain at the point of manufacture and to lubricate that chain throughout its service life. Even a fine spray of water adds to service life. Each different conveyor installation has different requirements regarding lubrication. Our technical team can advise on the best solutions to achieve long conveyor life.
