Rubber ribbed belts, also known as serpentine belts or ribbed drive belts, play a crucial role in a variety of mechanical systems, particularly in automotive applications. They are a type of belt designed to transfer power from the engine's crankshaft to various components, such as the alternator, power steering pump, water pump, and air conditioning compressor. The design and functionality of these belts have evolved over the years, becoming more sophisticated and efficient.

A serpentine belt is a long, continuous belt used to drive multiple peripheral devices in an engine, including the alternator, power steering pump, water pump, and air conditioning compressor. Unlike traditional belts, which are often separate and serve single functions, serpentine belts offer a more efficient and streamlined system. They are designed to minimize space and reduce the number of components required in the engine bay, making them a popular choice in contemporary automotive design.

The 90% in the designation of the 90% 20-inch serpentine belt generally refers to its efficiency in energy transfer. This metric indicates that the belt can convert up to 90% of the engine's power to drive auxiliary components like the alternator, water pump, power steering pump, and air conditioning compressor. The 20-inch measurement is the effective length of the belt, which is designed to fit a specific configuration of pulleys.
