car belt pulley

Micro rib V belts, also known as ribbed belts or serpentine belts, feature multiple longitudinal ribs that run along the length of the belt. This design allows for a larger contact area with the pulley, which increases the friction and provides better grip compared to traditional flat belts. The micro ribbing not only maximizes the transmission of power but also reduces slippage, which is essential in applications where consistent performance is necessary.

V-belts are designed to transmit power from the engine's crankshaft to different engine accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. The design and shape of the V-belt allow it to grip the pulleys effectively, ensuring reliable power transfer. The name V-belt comes from the trapezoidal cross-section of the belt, which fits snugly into the grooves of the pulleys it drives, minimizing slippage and maximizing efficiency.
