Tsubaki offers Heavy Duty chains for applications that exceed the capabilities of Tsubaki ANSI G8 standard roller chain. Heavy Duty chain should be considered in the following situations:
•Harsh environments where the chain will be subjected to heavy impact.
•Compact drives for equipment or machines that must work in tight spaces.
•When higher transmission power, allowable load or tensile strength is required.
•When a lower rate of elastic elongation is required.
HT Series chain provides a (10% to 20%) higher Tensile Strength than ANSI G8 Series chain by using through-hardened pins and link plates of the next larger pitch size in ANSI G8 series. HT Series chain also provides a higher shock load resistance and is best suited for low operating speeds - up to 50 m/min. Dimensions of the chain are identical to the H Series chain.
