RS-HT Series Roller Chain Tsubaki RS-HT Series Roller Chains
HT Series

HT Series Chains have a greater ultimate tensile strength (plus 15-30%) over ANSI standard roller chains by using through hardened pins and link plates of next larger chain sizes. These chains also provide a greater shock load resistance. The dimensions of the chains are identical to ANSI Heavy Series standard roller chains.
