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

1.1 transmission chain regular Roller Chains. These chains are designed for general usage.
1.2 High Performance Chains. These chains possess higher tensile power and greater fatigue power.
1.3 Lube-Totally free Chains. These chains have longer use life than regular chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with special 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 numerous types of chains available
