Product Description

Poly Ribbed V Belt

A Poly V-Belt, also called a multi-rib or serpentine belt, is a power transmission component featuring multiple parallel V-shaped ribs on its inner surface. 

Made from durable synthetic rubber reinforced with tensile cords like polyester, it resembles several small V-belts joinedtogether, allowing efficient power transfer with minimal slippage. Its ribbed design offers high flexibility, smooth operationwith reduced vibration and noise, and uniform stress distribution for extended lifespan.

PK belt, short for "Poly - Rib K type" belt, is a high-performance multi - rib belt widely used in power transmission scenarios. It has gradually replaced traditional V - belts in many fields due to its excellent structural design and performance advantages.It is a type of multi - rib belt with a longitudinal ribbed structure on its inner surface.

STRUCTURE

1.These are visible identifiers. They help technicians quickly recognize belt type, size, or manufacturer details, making replacement and maintenance simpler.

2.The synthetic tension members (the yellow, twisted - looking parts) are key for strength. The "balanced twist cord" design ensures the belt stays centered on pulleys (neutral tracking), preventing misalignment, reducing wear, and keeping power transmission efficient.

3.The rubber layer bonds different components of belt (like the tension members and the outer rubber). It maintains structural integrity, so layers don't separate, ensuring consistent performance and longevity.

4.EPDM (Ethylene - Propylene - Diene Monomer) rubber is the outer material. It's durable, resistant to heat, weather, and wear. The "highly engineered" formula makes the belt run quietly and last a long time, even in tough conditions (like hot engine bays).

5.The ribs are precisely shaped. This ensures the belt fits tightly in pulley grooves, maximizing contact area. More contact means better power transfer, less slippage, and smoother operation.

OUR ADVANTAGES

1) Wide breadth but thin belt, excellent elastic and flexural property.
2) High transmission efficiency under the operating environment of high speed rotation, reverse flexure, etc.
3) Core Rubber with high tension and low elongation, while the consistent tension is maintained during operation.
4) Excellent heat - resistance, oil proof, and wearing resistance.
5) Less Slip while large transmission effect during the operation.
6) Less noise during the operation.

High - efficiency power transmission: The ribbed structure expands the contact area with the pulley.Strong environmental adaptability: It has multiple properties such as heat resistance, oil resistance, wear resistance and antistatic.Stable and quiet operation: The uniform load distribution of the multi - rib structure reduces vibration during operation.
