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

1.1 Regular Roller Chains. These chains are made 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 put on life than regular chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with unique 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 several types of chains transmission chain available
