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

1.1 Standard Roller Chains. These chains are designed for general usage.
1.2 High Performance 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 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 several types of chains available
