Gates 4430V850 is a Multi-Speed Belt with RVS-I section, 30° angle, 85.0" effective length, and notched construction. Designed for industrial variable-speed drives requiring smooth speed variation and high torque capacity. The notched profile provides increased flexibility and reduced heat buildup in compact drive configurations.

Power transmission systems do more than operate at constant speeds with constant outputs. Customers increasingly need variable speed systems to regulate the speed and rotational force, or output torque, of critical mechanical equipment. Our Multi-Speed belts are engineered for efficiency, energy savings and increased productivity at a wide range of speeds and speed ratios.

• Molded notches reduce belt bending stress around small diameter pulleys, reducing the heat generated by rapid flexing and preventing premature belt failure.
• Uniform composition and thickness of the undercord ensure smooth and silent running with minimal vibration at high speeds.
• Gates Multi-Speed belts self-adjust to the pulley groove, providing a wide range of speeds and speed ratios.
• In addition to the standard Multi-Speed belt line, special sizes (top width, thickness and angle) are available on request.
• Meets ARPM/RMA IP-3-2 oil and heat resistant standards.

FOR APPLICATIONS AT ANY SPEED.

In today's applications, power transmission systems do more than operate at constant speeds with constant outputs. Our customers increasingly need variable speed systems to regulate the speed and rotational force, or output torque, of critical mechanical equipment. Our Multi-Speed belts are engineered for efficiency, energy savings, and increased productivity at a wide range of speeds and speed ratios.

Features and Benefits

• Gates Multi-speed belt adjusts itself to the pulley groove without difficulty, providing a wide range of speeds and speed ratios.
• In addition to the standard Multi-Speed belt line, special sizes (top width, thickness and angle) are available on request.

A NOTCH ON YOUR BELT.

Gates designs molded notches in our belts to reduce the bending stress as the belt wraps around small diameter pulleys, thereby reducing the heat generated by rapid flexing to prevent premature belt failure. A relatively large, deep notch provides excellent flexibility for bending around pulleys by implementing the notch near the cord line.
