cnc timing belt

The term PK belt refers to a type of V-belt used in automotive and industrial applications. The “PK” designation indicates the belt's size and width, while “ ” signifies a specific measurement standard. These belts are designed to transmit power efficiently between pulleys by relying on friction. PK belts are particularly known for their durability and strength, making them suitable for various engine applications, from alternators and water pumps to air conditioning systems and power steering.

On the other hand, flat belts feature a rectangular cross-section and are generally used in applications that require a lower power transmission capacity compared to V-belts. These belts are typically made of flexible materials, which may include leather, rubber, or synthetic fibers. The design allows flat belts to be used over longer distances between pulleys, making them ideal for specific setups where space is restricted or the distance between components is considerable.
