The PK belt fan belt is a type of V-belt characterized by its trapezoidal cross-sectional shape, which allows for better grip on pulleys and reduced slippage. The PK designation refers to its dimensional specifications, including width and thickness, which are designed to meet the needs of a variety of automotive applications. PK belts are often made from durable materials like rubber, reinforced with fibers to withstand the considerable stresses and strains they encounter during operation.

Pulleys serve as integral components in any mechanical system utilizing V-belts. They change the direction of the driving force, facilitate multi-stage drives, and allow adjustments in speed and torque. The construction of a pulley plays a significant role in the overall performance of the V-belt system. Typically made from materials like cast iron or aluminum, pulleys need to have a specific profile that matches the V-belt to ensure optimal interaction and prevent premature failure.
