Heavy Series roller chains differ from the ASME/ANSI standard series in the extra thickness of the link plates and the extra length of the pins. These link plates have the same thickness as the link plates of ASME/ANSI chains having the next larger pitch. The thicker link plates provide greater capacity (approximately 10%) for absorbing shock loads. These chains are suitable in situations where the load is heavy or operating conditions are severe.
T Series chains have greater shock load resistance and higher ultimate tensile strength than comparable ASME/ANSI standard roller chains. This is accomplished by using thru hardened pins. The dimensions of the chains are identical to ASME/ANSI standard roller chains.
HT Series chains have a greater ultimate tensile strength (plus 15-30%) than ASME/ANSI standard roller chains by using thru hardened pins and link plates of the next larger chain size. These chains also provide greater shock load resistance. The dimensions of the chains are identical to those of the ASME/ANSI Heavy Series standard roller chains.
The dimensions of Super Series Chain are identical to those of ASME/ANSI standard roller chain. Super Series Chain has a wider waist link plate than our standard chain and special manufacturing techniques are used to produce the pitch holes. After heat treatment, the holes are then ball drifted for greater fatigue strength. The pins are thru hardened for greater shock resistance. Because of this, Super Series Chain has a Maximum Allowable Load 25-30% higher than our standard RS roller chain.
Super-H Series Chain has the same wide waist as Super Series. The link plate thickness is identical to those of the ASME/ANSI Heavy Series roller chains. The same special manufacturing techniques used in Super Series Chain are used to produce the pitch holes. The pins are thru hardened. Because of this, Super-H Series Chain has an even higher Maximum Allowable Load than the Super Series.
U.S. Tsubaki Ultra Super chains have superior strength, excellent durability, greater allowable load, higher breaking load, and are stronger than any other roller chain we manufacture. With 170% higher allowable load than that of ASME/ANSI RS standard chains, you can select up to two chain sizes smaller. U.S. Tsubaki Ultra Super chains will solve your specific driving and conveying problems relating to heavy shock load and/or space limitation.
1. RS standard sprockets can be used if the sprocket teeth have been hardened and the sprocket is not of the cast iron type.
2. Chain should be lubricated using:
a) drip method b) oil bath c) lubrication pump
3. Offset links are not available.
4. Riveted type chains will be supplied unless otherwise specified.
5. Chains cannot be coupled with RS standard chains.
