SI-80 Snapidle Chain Tensioner

For #80 #50-2 #35-4 Roller Chain

By being able to take up tension through the chain, tensioners eliminate the need for adjustable center distance drives. Since the tensioner "floats" on the chain drive and actually absorbs shock, it does not add to vibration in the drive.

Both sprockets will have the maximum chain wrap possible, thereby increasing chain life (load sharing) and sprocket life (the chain is unable to crawl out of the teeth).
