Overview
The Gates B85 Hi-Power II V-belt (product number 9003-2085) is a classical wrapped, B-section power transmission belt designed for industrial and agricultural machinery. Featuring composite, multi-purpose construction, this belt resists oil, heat, ozone, sunlight, weather, and aging. The belt is made of EPDM (ethylene propylene diene monomer) rubber for resistance to weathering, oils, water, and some solvents. Its 88-inch outside circumference and standard B-section profile make it suitable for both single-belt and multi-belt drive systems.
Key Features
- Flex-Bonded Cords: Strongly bound to the body of the belt, resulting in equal load distribution and absorption of bending stress without cord deterioration.
- Gates Curves Design: Provide proper cord support and full contact with the sheave-groove for uniform loading, uniform wear, and increased belt life.
- Flex-Weave Cover: Constructed for longer cover life, providing extended protection to the core of the belt from oil, dirt, and heat.
- Fire-Resistant EPDM: Belt material is engineered to combat self-igniting, meaning your belt won’t catch fire from heat buildup even with severe slippage.
- V80 Matching System: All belts of the same type and size are more precisely matched than RMA and ISO standards require.
- Universal Application: Suitable for all industrial applications, including v-flat drives.
Technical Specifications
Length: 88 inches (O.C.) | Top Belt Width: 0.66 inch | Nominal Thickness: 0.41 | Weight: 0.95 lbs | Operating Temperature Range: −30°C to +60°C (−22°F to +140°F) | Meets RMA oil and heat resistant standards | REACH and RoHS 2 compliant
Typical Applications
The Gates B85 is engineered for demanding industrial, agricultural, and commercial power transmission systems. Common applications include conveyors, compressors, pumps, fans, and general machinery drives. Its composite construction and extended temperature range make it ideal for environments with exposure to oils, moisture, and temperature fluctuations. Recommended for Multi-Duty Sheaves.
