1. Transmission Chains
Power transmission chains are categorized into six major groupings.
1.1 Regular Roller Chains. These chains are created for general usage.
1.2 POWERFUL Chains. These chains have higher transmission chain tensile strength and greater fatigue power.
1.3 Lube-Totally free Chains. These chains have longer use life than regular chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with particular 
corrosion resistance.
1.5 Specialty 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
