Heavy type chain

Heavy type chain are also referred as heavy duty roller chain.The plate of the roller chain is thicker than normal plate.Heavy type chain provides
increased fatigue resistance for those drives subjected to heavy shock loads, multiple stops/starts or reversing as found in mining, quarrying, rock drilling, forestry and construction machinery.The specification is like,60H,80H,100H,120H,140H,160H,etc.
