84.5 serpentine belt

Round drive belts are characterized by their circular cross-section, which sets them apart from other types of belts, such as flat or V-belts. This unique shape allows them to operate efficiently with pulleys, offering smooth movement and flexibility. The material used in manufacturing these belts influences their performance characteristics, such as tensile strength, elasticity, and resistance to wear and temperature variations. Common materials include elastomers and thermoplastics, which are chosen for their durability and ability to withstand different environmental conditions.

A poly V belt is a type of belt that features multiple parallel ribs running along its length. This design allows for a greater surface area and better grip compared to traditional V-belts. The poly in its name denotes the belt’s polygonal rib design, which increases flexibility and allows for smoother operation in various machinery and automotive systems. Poly V belts are commonly used in engines, pumps, and various industrial equipment due to their ability to handle high-speed operations while providing stability and reliability.
