power steering belt

A poly V belt, also known as a multi-ribbed belt, is designed with multiple grooves running along its length. This design allows for a larger surface contact area between the belt and the pulleys it engages with, leading to improved grip and reduced slippage. The poly V belt is often made from high-quality materials like neoprene or EPDM rubber, which provide excellent flexibility, durability, and resistance to temperature fluctuations. The 135 in the 135J6 designation refers to the belt's overall length in millimeters, while J6 corresponds to its specific profile and rib design.

PK belts are typically part of the v-belt family, characterized by their trapezoidal cross-section. They are designed for use in a range of applications, including industrial machinery, agricultural equipment, and automotive engines. PK belts are particularly well-regarded for their ability to transmit power effectively between pulleys while minimizing slippage. The letters PK indicate a specific standard size and profile, allowing for compatibility with a wide variety of pulley systems.
