1. Transmission Chains
Power tranny chains are classified into six major groupings.

1.1 Standard Roller Chains. These chains are created for general usage.
1.2 High Performance Chains. These chains have higher tensile power and greater fatigue power.
1.3 Lube-Totally free Chains. These chains have longer wear life than standard chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with special corrosion transmission chain 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 plenty of types of chains available
