1. Transmission Chains
Power transmitting chains are classified into six major groups.

1.1 Standard Roller Chains. These chains are created for general usage.
1.2 POWERFUL Chains. These chains have higher tensile power and greater fatigue strength.
1.3 Lube-Free Chains. These chains have longer use life than regular chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with unique corrosion resistance.
1.5 Specialized Chains, Type 1. For particular applications.
1.6 Specialty Chains, Type 2. For general designs.
Within these six transmission chain groups, there are various types of chains available
