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

1.1 Regular Roller Chains. These chains are designed for general usage.
1.2 POWERFUL Chains. These chains possess higher tensile power and greater fatigue strength.
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 Specialty Chains, Type 1. For particular applications.
1.6 Specialized Chains, Type 2. For general designs.
Within these six groups, there are plenty of types of chains available
