Based on two simple effects and awarded the Innovation Prize of the State of Saxony, Germany, this minimal mechanisms has a new simple principle function. The elastic ring engages with the chain strands and rolls between them in a pre-stressed condition taking up the shape of an ellipse. The constantly opposing movements of the load and un-load strands cancel each other out, to the ”zero sum movement”, thereby holding the ROLL-RING in position.
We supply Roll-Ring Chain Tensioners to suit both BS and ANSI Chains, ROLL-RING Chain Tensioners can be applied in a wide variety of fields of mechanical engineering and are very easy to install.
ROLL-RING Chain Tensioners do not require any time for maintenance or adjustment; they are automatic, always exactly diametrical and self-lubricating in chain operation.
