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

1.1 Regular Roller Chains. These chains are created for transmission chain general usage.
1.2 High Performance Chains. These chains have higher tensile strength and greater fatigue strength.
1.3 Lube-Totally free Chains. These chains have longer use life than regular chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with special corrosion resistance.
1.5 Specialty Chains, Type 1. For specific applications.
1.6 Specialized Chains, Type 2. For general designs.
Within these six groups, there are several types of chains available
