Heavy Duty & Super Series Chain

Tsubaki’s  extensive line-up of Heavy Duty Roller Chains come in a wide array of products – all backed by Tsubaki’s outstanding reliability. These products are ideal for high-torque applications — with their increased standards for maximum allowable loads. Harsh environments with heavy shock loads? No problem. When an application’s capacity exceeds that of standard RS series roller chain, Heavy Series Chain delivers the same strength as a larger sized standard RS chain. When higher HP, tensile strength or maximum allowable load is required turn to Tsubaki H (Heavy) Series, HT Series, Super Series, Super H Series or Ultra Super Series.

Notable features:

  • Heavy Duty & Super Series Chain's link plates are same thickness as next size standard ANSI chain. Approximately 10% greater shock load capacity. Up to size 140 pins are through hardened. Above size 140 pins are case hardened.
  • Super Series Chain: 15% to 30% increase in tensile strength over standard ANSI chain. Link plates are same thickness as next size standard ANSI chain. Pins are through hardened.
  • High shock load capacity.
  • Wider link plate waist, through hardened pins, critically formed and ball drifted link plate holes provide 30% greater HP ratings and greater shock resistance over standard ANSI chain. Drop in replacement. Can substitute for next size larger standard ANSI chain.
  • Link plates are same thickness as next size Super series chain. Through hardened pins. 23% higher tensile strength and 40% higher max allowable load over standard ANSI chain. Can sub next size larger standard ANSI chain.
  • Higher tensile strength and 62% higher max load over standard ANSI chain. Longest wear life of any Tsubaki chain. Can substitute up to two sizes larger standard ANSI chain.
