Substantial reductions in energy costs and chain noise are said to result from the use of the Double Plus free flow chain from Tsubakimoto as slower motor speeds can be used: the chain conveys objects at 2.5 times faster than the chain speed.

The chain design features a large centre roller (which carries the conveyed object) and a smaller outer roller which supports the chain on a guide rail. When engaged, the large centre rollers rotate at the same rpm as the small rollers. Since the diameter of the large rollers is nearly 2.5 times that of the smaller ones, the conveyed objects move along approximately 2.5 times faster than the chain. As a result chain speeds up to 60% slower can be used without affecting the object conveying speed, giving noise levels some 15dB lower than those of plastic side roller chains.

The chain is available in five pitch sizes, 19.05mm, 25.4mm, 31.75mm 38.10mm and 50.8mm, and three material types, carbon steel, hard chrome plated steel, and stainless steel.
