V-belts and V-ribbed belts are power transmission drive belts with a triangular or trapezoidal cross section. They are available in a variety of belt materials, reinforcement styles, and speed configurations. Typically, V-belts and V-ribbed belts are used with mating pulleys in drives where speed ratio is not critical. HOME. PRODUCTS & SERVICES. MOTION AND CONTROLS. POWER TRANSMISSION.
