1. Transmission Chains
Power transmission transmission chain chains are classified into six major organizations.
1.1 Standard Roller Chains. These chains 
are created for general usage.
1.2 POWERFUL Chains. These chains possess higher tensile strength and greater fatigue strength.
1.3 Lube-Totally free Chains. These chains have longer wear life than regular chains without lubrication.
1.4 Environmentally Resistant Chains. Chains with special 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 various types of chains available
