What is PU Round Belt? Smooth Surface vs. Rough Surface

Introduction to PU Round Belt
PU (Polyurethane) round belts, also known as PU transmission belts, are common components in mechanical power transmission and conveyor systems. Compared to traditional leather belts, PU round belts offer superior wear resistance, durability, anti-slip properties, and ease of maintenance. For instance, traditional textile machines often use leather round belts, which are prone to slipping. Replacing these with PU round belts not only increases durability but also resolves slippage issues. PU round belts can be classified into smooth surface and rough surface types based on their surface characteristics. This article will provide a detailed comparison of smooth and rough surface PU transmission belts to help you choose the best one for your application needs.

Characteristics and Applications of Smooth Surface PU Round Belts

Smooth surface PU round belts, also known as:

Smooth PU transmission belt
Smooth PU conveyor belt
Smooth PU round belt
PU smooth belt
PU smooth drive belt
Smooth urethane transmission belt
Smooth urethane round belt

Key characteristics of Smooth PU Round Belts include:

Smooth Surface: Resistant to dirt and easy to clean.
High Elasticity: Excellent elasticity suitable for various mechanical transmission systems.
High Tear and Tensile Strength: Capable of withstanding high tensile and tearing forces.
Chemical and Oil Resistance: Good resistance to chemicals and oils.
Wear Resistance: Surface is resistant to wear, ensuring a long service life.
Low Noise: Operates quietly, suitable for noise-sensitive environments.

Smooth surface PU round belts are suitable for:

Light to Medium Load Transmission: Ideal for transporting agricultural products, fruits, vegetables, newspapers, and other general materials.
Food and Packaging Industries: Especially suitable for food processing and packaging equipment due to their easy-to-clean nature.
Textile and Printing Machinery: Their excellent elasticity and wear resistance make them perfect for textile machines and printing equipment.

Characteristics and Applications of Rough Surface PU Round Belts

Rough surface PU round belts have the following characteristics:

Rough Surface: Reduces friction coefficient and enhances wear resistance.
Excellent Physical Properties: High elasticity, tear resistance, chemical resistance, and oil resistance.
Suitable for Medium Load Transmission: Capable of handling higher loads and suitable for longer distance conveyance.

Rough surface PU round belts are suitable for:

Medium Load Transmission: Suitable for transmission systems with heavier loads.
Long-Distance Conveyance: Their wear resistance makes them ideal for long-distance transportation.
Various Industrial Equipment: Including packaging machines, canning factory conveyor equipment, textile machines, cardboard processing plants, agricultural transportation equipment, etc.

How to Connect PU Round Belts

PU round belt connectors are electrically heated tools designed for joining PU transmission belts. The operation is simple, and it allows for customized belt lengths for both smooth and rough surface PU belts. Although the connected PU round belts have joints, they do not require mold costs and offer a longer lifespan compared to seamless O-ring belts, making them cost-effective. And the connection procedure is as follow:

Heat the iron plate by plugging in the PU round belt connector.
Cut the belt: Trim the PU round belt to the desired length.
Welding: Press the ends of the belt against the heated iron plate until they melt, then allow them to cool completely.
Trimming: Use diagonal pliers to trim the protruding joint to ensure it is smooth.

Conclusion
Smooth PU round belts and rough PU round belts each have their distinct advantages, making the choice dependent on specific application needs. Smooth PU round belts are suitable for light loads and clean environments, while rough PU round belts are better for medium loads and long-distance transportation. Once you determine whether you need a smooth or rough surface PU round belt, simply ensure you have the correct diameter, and you can cut and weld the belt to the desired size for durable and efficient mechanical power transmission.

In addition to the applications mentioned above, PU transmission belts are also suitable for textile machines, printing machinery, food machinery, ceramic processing lines, canning conveyor systems, woodworking lines, glass production lines, tile production lines, and other industrial equipment requiring mechanical transmission. Understanding the characteristics and applications of smooth and rough surface PU round belts will help you make the best choice for your industrial transmission and conveyor needs, thereby improving equipment efficiency and lifespan.
