There are several types of V-belts designed to meet various operational needs. These include classical V-belts, narrow V-belts, and cogged V-belts. Classical V-belts are widely used in numerous applications, while narrow V-belts provide a more compact design for applications with space constraints. Cogged V-belts feature notches along the belt's length that improve flexibility, allowing for better gripping on smaller pulleys and enhancing performance in high-speed applications.

The “4PK” designation refers to the specific configuration of the belt itself. The 4 indicates that the belt has four ribs, while PK signifies that it is part of the multi-ribbed belt category, also known as serpentine belts. This type of belt is designed to drive multiple accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. The use of multiple ribs provides a greater surface area for friction, enabling the belt to efficiently transfer power from the engine crankshaft to the various components.
