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

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-Totally free Chains. These chains have longer put on life than standard chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with special transmission chain corrosion resistance.
1.5 Specialized Chains, Type 1. For specific applications.
1.6 Specialty Chains, Type 2. For general designs.
Within these six groups, there are numerous types of chains available
