Overview
The Gates 9389-2085 2/5VX850 Super HC Powerband Belt is a two-strand banded V-belt engineered for multi-belt drive systems requiring consistent load distribution and shock load resistance. The PowerBand construction allows multiple belts to function as one belt, with even load distribution and each strand fitting securely in the sheave groove. This 5VX section belt features a 1.2500 in top width, 85 in outside length, 0.5469 in height, and is constructed with polyester reinforcing cord. Patented ethylene material provides -60°F to +250°F temperature range to resist belt cracking.
Key Features
- Recommended for multiple V-belt drives exposed to pulsating or heavy shock loads which can make belts whip, turn over or jump off the drive
- Tie band assures high lateral rigidity, guiding the belt in a straight line and preventing it from coming off the drive
- Concave sidewalls provide proper cord support and full contact with the sheave-groove for equal loading and uniform wear
- Flex-bonded cords result in equal load distribution and absorption of bending stress without cord deterioration
- Oil-resistant with RMA standards compliance and cogged construction for improved flexibility
