HT Series

g8-logo

HT Series chain provides a significantly higher Tensile Strength (up to 19%) than ANSI G8 Series chain by applying through-hardened pins and link plates of the next larger pitch size in ANSI G8 series.

Compared to the previous series, the wear life of the HT Series is doubled by using solid bushes instead of curled bushes.

HT Series chain also provides a higher fatigue strength and is best suited for low operating speeds (up to 50 m/min). Dimensions of the chain are identical to the H Series chain.
