Overview
The Gates 5VX850 is a premium Super HC molded notch V-belt designed for heavy-duty industrial power transmission. When power transmission applications require high horsepower in limited drive weight or space, Gates Super HC molded notch belts provide a solution through proprietary ethylene construction that delivers up to three times the horsepower versus comparably sized belts. This 85-inch nominal outside circumference belt combines superior flex, load-carrying capacity, and durability for demanding motor-to-driven equipment applications.
Key Features
- Part of Gates’ V80 matching system, guaranteeing precise matching beyond RMA and ISO standards
- Molded notches reduce bending stress as the belt wraps around small diameter pulleys
- EPDM rubber provides resistance to weathering, oils, water, and some solvents
- Meets Gates UNISET tolerances allowing installation without matching
- Meets ARPM/RMA IP-3-2 oil and heat resistant standards and IP-3-3 static conductivity requirements; REACH and RoHS 2 compliant
- Patented Flex-Weave cover provides extended protection from oil, contaminants, and heat for longer belt life
Technical Specifications
The Gates 5VX850 delivers reliable performance across a broad temperature range and is optimized for industrial machinery requiring compact drive designs and high power density.
Typical Applications
- Industrial pump and motor drives with space constraints
- Compressor and HVAC equipment power transmission
- Industrial heavy-duty narrow section V-belt drives
- High-speed, high-ratio gear systems requiring small pulley diameters
- Conveyor and material handling systems
