1. Transmission Chains
Power transmission transmission chain 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 strength and greater fatigue power.
1.3 Lube-Free Chains. These chains have longer put on life than standard chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with unique corrosion resistance.
1.5 Specialized Chains, Type 1. For specific applications.
1.6 Specialized Chains, Type 2. For general designs.
Within these six groups, there are many types of chains available
