Premium Rubber Lagging Pulley China Factory and Trusted Suppliers
Our premium Rubber Lagging Pulleys are engineered to provide maximum traction and superior wear resistance for heavy-duty conveyor systems. By applying a high-performance rubber coating to the drum surface, these pulleys effectively eliminate belt slippage and protect the core metal from corrosive environments, ensuring a stable and efficient material transport process.
To meet diverse industrial demands, we offer a comprehensive range of rubber materials including NBR, CR, HYPLON, PU, SBR, and SR. Whether your operation requires extreme heat resistance, oil repellency, or high abrasion resistance, our lagging solutions are fully customizable to match your specific product design and environmental requirements.

Frequently Asked Questions
For environments with high oil exposure, NBR (Nitrile Butadiene Rubber) is highly recommended due to its excellent oil and fuel resistance properties.
Rubber lagging increases the coefficient of friction between the pulley and the belt, preventing slippage and reducing wear on the belt's carrying side.
High adhesion strength prevents the rubber from peeling or delaminating from the metal drum under heavy loads and thermal expansion.
Yes, we customize hardness based on the pulley type; for example, Driving Pulleys typically require a hardness of ≥70 Shore A for maximum grip.
Key factors include the choice of rubber compound, the abrasiveness of the conveyed material, operating temperature, and the belt tension settings.
Absolutely. We provide detailed diagrammatic drawings including parameters like belt width, diameter (Φ), and length (L) for client approval before production.
