Roller Chain - Tsubaki

Heavy Duty Roller ChainAn introduction to Heavy Duty and SUPER Series ChainDrive ChainTsubaki offers Heavy Duty and SUPER Series roller chains for applications that exceed the capabilities of Tsubaki ANSI standard RSRoller Chain. These heavy duty applications include the following:1. Severe operating conditions such as heavy shock loads.2. Where space to put the chain is limited. A Heavy Duty chain will often deliver the same tensile strength of a larger size ofStandard RS Roller Chain.3. Operating conditions that require higher horsepower ratings, maximum allowable load and tensile strength.H (Heavy) Series:H (Heavy) Series roller chain differs from ANSI (RS) standard series roller chain only in the extra thickness of the link plates. Theselink plates have the same thickness as the link plates of the next larger size of ANSI standard series. The thicker link plates provide(approximately 10%) greater capacity for absorbing shock loads. Through hardened pins are used up to size 140 chain. Above size140, the pins are case hardened. H series chains are especially suited to situations where the load is heavy and operating speeds arelow (up to 165 ft./sec.), or where operating conditions are severe.SUPER Series:The dimensions of this series are identical to those of ANSI (RS) standard series roller chain. The special design of the SUPER serieslink plates delivers exceptional performance. The pitch holes are critically formed and drifted to improve their allowable tension by25%-30%; and the pins are through hardened for greater shock resistance. SUPER series chains offer horsepower ratings 30%greater than the equivalent size ANSI standard chain. SUPER series chains can be used to replace the next larger size of ANSIstandard chain, making it ideal for applications where space is limited.HT Series:HT series chains provide a (15%-30%) greater ultimate tensile strength over ANSI standard roller chain by using through hardenedpins and link plates of the next larger ANSI standard chain sizes. HT Series chains also provide a greater shock load resistance.The dimensions of the chain are identical to the H Series (above). HT Series chains also provide a greater shock load resistance andare best suited for low operating speeds – up to 165 ft./sec.SUPER-H Series:The thickness of SUPER-H series link plates is the same as the next larger size of SUPER series chain. The pins are also throughhardened which provides a 13% greater ultimate tensile strength and 6% greater allowable tension than SUPER series chain.SUPER-H series chains can be used to replace the next largest size of ANSI standard chain, making it ideal for applications wherespace is limited. It is best suited for low speed operating conditions – up to 165 ft./sec.ULTRA SUPER Series:ULTRA SUPER series offer longer wear life, greater allowable load, higher tensile strength than any other Tsubaki roller chain. Thischain is well suited for applications where there are space limitations. The heavy duty construction of the ULTRA SUPER serieschains allows it to replace an (up to) two sizes larger ANSI standard roller chain. It is best suited for low speed operating conditions –up to 165 ft./sec.A-46
