  • Super (Heavy Duty) Drive Chains

RS-HT Roller Chain

The outer and inner plates are one size thicker than RS Roller Chain.

The chain has 19% greater tensile strength than RS Roller Chain, and so is ideal for applications requiring high tensile strength and low elastic elongation.

The December 2016 upgrade gives RS-HT Chain twice the wear life and the option of a slip fit connecting link.

RS-HT Roller Chain

1. Features/Applications

High kW ratings, tensile strength, shock absorption
High tensile strength. Ideal for lower frequency lifting applications, and low speed drives up to 50m/min. Recommend for usage of metalworking machinery, forestry, construction machinery etc.

2. Caution

  • Tsubaki Heavy Duty Roller Chains are designed for low to medium speed transmission. RS Roller Chain should be used for higher speed ranges that do not appearing in the kilowatt rating tables.
  • Use sprockets made of S35C or higher carbon steel. Small sprockets must have hardened teeth. Cast iron sprockets cannot be used. Tsubaki's RS Sprocket - Heavy Duty Type (hardened teeth), which are hardened throughout, but specially hardened on the bottom of the teeth, are recommended. Standard RS sprockets cannot be used for RS-HT/Super-H multi-strand roller chains due to differences. (Contact us for special configurations.)
  • Consider Tough Tooth sprockets, which are optimal for Heavy Duty Chain.
