1. Transmission Chains
Power transmission chains are classified into six major groups.
1.1 Regular Roller Chains. These chains 
are made for general usage.
1.2 POWERFUL Chains. These chains possess higher tensile transmission chain strength and greater fatigue strength.
1.3 Lube-Totally free Chains. These chains have longer use life than standard chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with unique corrosion resistance.
1.5 Specialized Chains, Type 1. For particular applications.
1.6 Specialized Chains, Type 2. For general designs.
Within these six groups, there are plenty of types of chains available
