Overview
The Gates 3/5VX750 Super HC PowerBand is a premium industrial V-belt engineered for drives exposed to pulsating loads, shock loads, and vibration. This gates super HC notched, banded power transmission V-belt reduces bending stress as the belt wraps around small diameter pulleys. The 75″ overall circumference, 5VX section design features three bonded ribs that function as a single mechanical unit, eliminating the belt slippage and misalignment common in traditional multi-belt drives.
Key Features
- EPDM rubber construction provides resistance to weathering, oils, water, and some solvents.
- Molded notches on the underside create the flexibility needed to fit smaller diameter sheaves while maintaining strength and traction.
- A high-strength tie band permanently joins two or more belts to provide lateral rigidity, guiding the belt in a straight line and preventing it from coming off the drive.
- Flex-weave cover provides flexibility and strength, with cords strongly bonded to the body for equal load distribution and reduced bending stress.
- Super HC belts are part of Gates’ V80 matching system, which guarantees more precise matching than RMA and ISO standards require, resulting in even load distribution on multi-belt drives and better wear.
- This V-belt is suitable for use with multiple V-belt drives exposed to pulsating or heavy shock loads that can make belts whip, turn over, or jump off the drive.

Typical Applications
Gates PowerBand belts are engineered for drives that are subject to pulsating loads, shock loads or extreme vibrations. By joining several Super HC V-belts together the Super HC PowerBand offers a maintenance-free solution for drives where single belts vibrate, turn over or jump off the pulleys. These belts are commonly used in conveyors, blowers, pumps, compressors, and other industrial motion control equipment where belt stability and reliability are critical to uptime.
