Their unique patented construction provides smooth, quiet operation with less vibration. Gates curves provide proper cord support and full contact with the sheave-groove for uniform loading, uniform wear, and increased belt life. Flex-Bonded cords are strongly bonded to the body of the belt resulting in equal load distribution and the absorption of bending stress without cord reduction. Flex-Weave® cover is a patented fabric construction for longer cover life, providing extended protection to the belt core from oil, dirt, and heat. Mars is a leader in the industry for obvious reasons. They make great solutions.
