In many of today’s extreme applications, even Tsubaki’s high quality standard chains won’t go the distance. In response, Tsubaki produces a range of Heavy and Super Series Chains specifically designed for handling shock loads or solving space limitation problems.

super series (click here for dimensions)

The dimensions of this series are identical to those of ANSI standard roller chain. The special design of the Super Series link plates delivers exceptional performance. The pitch holes are critically formed and drifted to improve their allowable tension by 25-30%, and the pins are through-hardened for greater shock load resistance.

• SUPER80 - pitch 25.40 mm
• SUPER100 - pitch 31.75 mm
• SUPER120 - pitch 38.10 mm
• SUPER140 - pitch 44.45 mm
• SUPER160 - pitch 50.80 mm
• SUPER200 - pitch 63.50 mm
• SUPER240 - pitch 76.20 mm

HT series (click here for dimensions)

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

• RS60HT - pitch 19.05 mm
• RS80HT - pitch 25.40 mm
• RS100HT - pitch 31.75 mm
• RS120HT - pitch 38.10 mm
• RS140HT - pitch 44.45 mm
• RS160HT - pitch 50.80 mm
• RS200HT - pitch 63.50 mm
• RS240HT - pitch 76.20 mm

super-H series (click here for dimensions)

The thickness of Super-H Series link plates is the same as the next larger size of Super Series chain. The pins are also through-hardened. As a result, the chain has an even greater ultimate tensile strength and allowable tension than Super Series chain.

• SUPER80H - pitch 25.40 mm
• SUPER100H - pitch 31.75 mm
• SUPER120H - pitch 38.10 mm
• SUPER140H - pitch 44.45 mm
• SUPER160H - pitch 50.80 mm
• SUPER200H - pitch 63.50 mm
• SUPER240H - pitch 76.20 mm

ultra super series (click here for dimensions)

Field tests show that Tsubaki Ultra Super Series chains have a greater ultimate tensile strength and allowable tension than any other roller chain manufactured. With the Ultra Super Series, a chain up to two sizes smaller than standard chain may be selected.

• US100 - pitch 31.75 mm
• US120 - pitch 38.10 mm
• US140 - pitch 44.45 mm
• US160 - pitch 50.80 mm
• US200 - pitch 63.50 mm
• US240 - pitch 76.20 mm
