1. Transmission Chains
Power transmission chains are categorized into six major groupings.

1.1 transmission chain standard Roller Chains. These chains are designed for general usage.
1.2 POWERFUL Chains. These chains have higher tensile strength and greater fatigue power.
1.3 Lube-Totally free Chains. These chains have longer use life than standard chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with special 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 many types of chains available
