Overview
The Gates 9388-2085 2/3VX850 Super HC PowerBand is a two-strand 3VX molded notch V-belt engineered for heavy-duty industrial applications requiring precise power transmission and load sharing. This Gates Super HC PowerBand configuration delivers the reliability and efficiency needed in compact pulley systems where space constraints demand smaller sheaves without sacrificing performance.
Key Features
- PowerBand® Construction: Multiple belts function as a single unit with even load distribution and each strand fits securely in the sheave groove
- Molded Notch Design: Notches molded into the belt during manufacturing increase flexibility making this belt well suited for drives with smaller diameter sheaves
- Flex-Bonded Polyester Cord: 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 deterioration
- EPDM Compound: Fibre-loaded EPDM resists high heat, ozone, and sunlight exposure with enhanced cord support
- Extended Temperature Range: -60 to 250 deg F operating temperature capability
- Tie-Band Lateral Rigidity: Integrated tie band guides the belt in a straight line and prevents belt slip-off
