Understanding Plain Rubber Pulley Lagging HP-N65 and HP-V65

Rubber pulley lagging is an essential component in various industrial applications, designed to enhance pulley efficiency and extend their lifespan. It acts as a protective layer, improving the interaction between the pulley and the belt, reducing slippage, wear, and tear. Hanpeng's HP-N65 and HP-V65 plain rubber pulley lagging are high-performance solutions specifically engineered for both wet and dry conditions. These laggings are perfect for a wide range of applications, from driven to non-driven pulleys in fabric and steel cord belts.

Plain Rubber Pulley Lagging Product Overview

The HP-N65 and HP-V65 rubber pulley lagging are engineered to provide superior performance under demanding conditions. Manufactured using a blend of BR (butadiene rubber), NR (natural rubber), and SBR (styrene-butadiene rubber), these products deliver the ideal balance of durability, flexibility, and resilience.

• HP-N65: The standard rubber lagging suitable for most general applications.

• HP-V65: A flame retardant version designed for applications requiring enhanced safety in hazardous environments.

These laggings are particularly suited for use in material handling systems, including conveyor systems in industries like mining, cement, and manufacturing.

Key Specifications and Features

• Polymer Composition: The HP-N65 and HP-V65 are made from a high-quality blend of BR, NR, and SBR. This composition provides excellent elasticity, resilience, and wear resistance, making the lagging highly durable.

• Tensile Strength: The lagging offers a tensile strength of ≥ 15 N/mm3, ensuring that it can withstand heavy-duty applications and maintain its integrity even under intense mechanical stress.

• Abrasion Resistance: With an abrasion rate of 120 mm3, the lagging is designed to resist surface wear, significantly extending the service life of both the lagging and the pulleys.

• Specific Weight: The product has a specific weight of 1.15 g/cm³, giving it a stable and robust structure that enhances performance and longevity.

• Hardness: The lagging has a Shore A hardness of 63±5, providing a balanced level of softness for excellent contact with the belt while maintaining durability under heavy loads.

• Elongation at Break: The product is capable of ≥ 450% elongation at break, ensuring flexibility and adaptability in various applications.

• Colour: The rubber lagging comes in a black finish, offering a professional, industrial appearance suitable for a wide range of settings.

Benefits of Plain Rubber Pulley Lagging

• Smooth Lagging Surface: The lagging features a smooth surface that minimizes friction, reducing slippage between the belt and the pulley, thus enhancing the overall efficiency of the system.

• Improved Coefficient of Friction: The HP-N65 and HP-V65 increase the coefficient of friction, ensuring better grip between the pulley and the belt, which reduces slippage and enhances belt performance.

• Protection Against Wear and Corrosion: Both types of lagging are designed to protect the pulley from wear and corrosion, ensuring that the pulley maintains its structural integrity over time, even in harsh environments.

• CN Bonding Layer: The CN bonding layer provides fast and effective adhesion to the pulleys, ensuring a secure and long-lasting attachment that won't degrade under stress.

Plain Rubber Lagging vs Other Types

Rubber is one of the most widely used materials for pulley lagging due to its affordability, versatility, and ability to provide effective protection to pulleys in various industrial applications. Rubber lagging comes in different forms, including Plain Rubber Lagging, Diamond Grooved Lagging, Herringbone Grooved Lagging, and Chevron Grooved Lagging, each suited for specific types of conveyor systems.

Plain Rubber Lagging

Plain Rubber Lagging is most commonly used for non-driven pulleys in industrial conveyor systems. It provides improved traction without excessively increasing friction, which can lead to premature belt wear. This type of lagging is ideal for scenarios where consistent, moderate friction is needed to maintain smooth and efficient belt movement. For drive pulleys, we recommend using our Diamond Rubber Pulley Lagging.

Use Cases for Plain Rubber Lagging:

Non-Driven Pulleys: Plain rubber lagging is a perfect fit for non-driven pulleys, offering reliable traction without causing excessive friction, making it ideal for material handling in industries such as mining, cement, and material transport.

Wet and Dry Conditions: Suitable for environments with both wet and dry conditions, where high abrasion resistance and reduced slippage are crucial.

Heavy-Duty Conveyors: It is widely used in heavy-duty conveyor systems where excessive friction could damage the belt, making it an efficient solution for industries like metallurgy and heavy manufacturing.

Diamond/Herringbone/Chevron Grooved Rubber Lagging

On the other hand, Diamond, Herringbone, and Chevron Grooved Rubber Lagging are designed for pulleys requiring higher friction, which is essential for increasing grip between the pulley and the belt. The diamond-shaped grooves enhance flexibility and allow the lagging to move and bend with the belt, providing better traction and water shedding to prevent slippage.

Use Cases for Grooved Rubber Lagging:

Driven Pulleys: These types of grooved lagging are more suitable for driven pulleys that need extra grip to transfer torque efficiently without slippage.

Wet or Slippery Environments: The grooves help shed water and reduce the chance of slippage, making them ideal for applications in wet or slippery environments, such as in the mining and port industries.

High-Friction Applications: Suitable for industries like agriculture, food processing, or any system requiring high friction to move heavy loads or materials.
