Tightener Roll Ring (906 to 920)

[Features]
· Roll-Ring is a drive tensioner for chains created based on a new concept.
· The tension is automatically applied to the drive chain to absorb vibration.
· Designed based on rotation and elasticity principles, so it maintains smooth chain drive with little tension force.
· Unlike conventional tensioners, mounting stays and flanges are not required and there is also no need for machining of screw holes, etc.
· Can be mounted by hand in a few seconds, with no tools required. Adjustment after mounting is also unnecessary.
· Made from high-performance elastic materials. Absorbs chain vibration, provides smooth rotation by reducing noise and improves the lifespan of drive mechanism without damaging chains, sprockets, bearings, etc.
· Absolutely no lubrication or other such maintenance required.
· Can handle both forward and reverse drive directions.
· Can be mounted in both vertical and horizontal directions.
· Can be used in a wide range of temperatures. It can also be used in places exposed to water and dusty places, so it is useful for machinery in any field.
