Tensioner that clamped onto chains. Automatically adds tension to drive chains, absorbs vibration, and provides smooth rotation.
[Features] · The roll ring is a drive tensioner for chains created based on a new concept. · Automatically adds tension to drive chains, absorbs vibration, and provides smooth rotation. · Designed based on rotation principles and elasticity principles, so it maintains smooth chain drive with little tension force. · Differs from conventional pensioners in that mounting stays and flanges are not required, nor is any machining of screw holes and the like. · Can be mounted by hand in a few seconds, with no tools required. Can also be adjusted after mounting. · Made from high-performance elastic materials. Absorbs chain vibration and provides smooth rotation, reducing noise and improving drive mechanism life without damaging chains, sprockets, springs, 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. · Usable in a wide range of temperatures. Can also be used in places exposed to water and dusty places, so it is usable for machinery in any field.
