The PK belt, also known as a serpentine belt or ribbed belt, is a key element of the engine's accessory drive system. It is named for its PK section profile, which features a series of ribs that permit better grip on pulleys. This design allows the belt to efficiently drive multiple components such as the alternator, power steering pump, water pump, and air conditioning compressor. The effective operation of these systems is crucial for the vehicle’s performance, safety, and comfort.

3. Polyurethane Known for its exceptional abrasion resistance, polyurethane belts are often used in high-load applications where durability is crucial. Polyurethane exhibits a high level of tensile strength and tear resistance, making it suitable for environments where belts are subjected to significant wear and tear. Its lightweight nature and flexibility also allow for easier handling and installation.

One of the primary advantages of banded belts is their enhanced durability. The composite structure of multiple strands allows for weight distribution across the belt, which reduces wear and tear. This durability is particularly important in heavy-duty applications where machines are subjected to extreme conditions and rigorous operations. Industries that rely on conveyor systems, for example, benefit significantly from the longevity of banded belts, resulting in lower maintenance costs and reduced frequency of replacements.

Despite their numerous benefits, classic V belts are not without challenges. One of the primary limitations is their susceptibility to stretching over time, which can lead to decreased performance. Additionally, they may not be suitable for high-speed applications, as they can experience vibration and noise at increased velocities.
