Overview
The Gates B112 Hi-Power II V-belt is a composite, multi-purpose power transmission belt engineered for reliable operation in industrial and agricultural machinery. Featuring composite, multi-purpose construction, Gates® Hi-Power II® B112 Belt resists oil, heat, ozone, sunlight, weather, and aging. Gates B112 Hi-Power II® belts are suitable for all industrial applications, including v-flat drives. The B112 designation indicates a classical B-section belt with a 115-inch outside circumference.
Key Features
- EPDM belt material engineered to combat self-igniting, meaning your belt won’t catch fire from heat buildup even with severe slippage.
- Flex-Bonded Cords are strongly bound to the body of the belt, resulting in equal load distribution and absorption of bending stress without cord deterioration.
- Gates® Curves provide proper cord support and full contact with the sheave-groove for uniform loading, uniform wear, and increased belt life.
- Flex-Weave® Cover is constructed for longer cover life, providing extended protection to the belt core with built-in static connectivity to protect from the toughest operating environments.
- V80 matching system that ensures that every B112 belt can be used in a matched set, regardless of batch or lot.
- RMA oil and heat resistant standards compliant.
