HT Series

Tsubaki Heavy Duty HT Chain

HT Series chain provides a (10% to 20%) higher Tensile Strength than ANSI G7 Series chain by using through-hardened pins and link plates of the next larger pitch size in ANSI G7 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.
