Tsubaki Heavy Duty Drive Chain Series
The superior performance of Tsubaki Heavy Duty chains is the result of a comprehensive quality control network that begins with selection of the world's finest steel materials. It continues with inspection and analysis of quality and performance in 20 different work areas.
The dimensions of these series are identical to those of ANSI G8 Series chain. The special design of the Super Series link plate delivers exceptional performance. The Lube Groove Bushes ensure longer and better lubrication which results in an extended chain life. The pin holes are critically formed and ball drifted, while the pins are through-hardened for greater fatigue strength.
Super Series chains offer 9% higher tensile strength than the equivalent size ANSI G8 Series chain. Super Series chains can be used to replace the next larger pitch size of ANSI G8 Series, making them ideal for applications where chain space is limited. Best suited for low speed operating conditions (up to 50 m/min).
RS-HT Series chain provides a significantly higher Tensile Strength (up to 19%) than ANSI G8 Series chain by applying through-hardened pins and link plates of the next larger pitch size in ANSI G8 series.
Compared to the previous series, the wear life of the RS-HT Series is doubled by using solid bushes instead of curled bushes.
RS-HT Series chain also provides a higher fatigue strength and is best suited for low operating speeds (up to 50 m/min). Dimensions of the chain are identical to the H Series chain.
The thickness of the Super-H Series link plates is the same as the next larger pitch size of Super Series chain. The pins are also through-hardened which provides a higher tensile strength and a higher fatique strength than Super Series chain. The pin holes of the outer link plates are critically formed and ball drifted. The holes of the roller link plates are ring coined to increase fatique strength.
Super-H Series chains can be used to replace the next larger size of ANSI standard chain, making them ideal for applications where space is limited. Best suited for low speed operating conditions (up to 50 m/min).
Ultra Super Series
Ultra Super Series offer longer wear life, higher shock load resistance and higher tensile strength than any other Tsubaki roller chain. The pins are through-hardened and the pin holes are critically formed and ball drifted. The diameter of the pins has been increased. This chain is well suited for applications where there are space limitations. The heavy duty construction of the Ultra Super Series chain allows it to replace chains up to two pitch sizes larger ANSI G8 Series chain. It is best suited for low speed operating conditions up to 50 m/min.
