How Do Rubber Open-End Belts Ensure Reliable Power Transmission?

When it comes to high-performance mechanical systems, LSL® rubber open-end belts are a proven solution for precision power transmission. These belts are specially engineered for industries that demand strength, flexibility, and wear resistance in a wide range of operational conditions. At our factory, we manufacture LSL® belts using top-grade materials and reinforcement options to ensure long-lasting, efficient performance—even under high tension.

One of the defining features of LSL® rubber open-end belts is their construction. Made from premium neoprene rubber combined with glass fiber reinforcement, these belts offer exceptional tensile strength, low elongation, and high dimensional stability. To further enhance durability, our factory adds specially treated canvas and colloid layers to either the tooth surface or the back of the belt during production. This results in reduced surface wear and extended belt life, even under continuous or heavy-duty usage.

We understand that different applications require different strength characteristics. That’s why our factory offers optional reinforcement cords including glass fiber, aramid, and steel, allowing for customized solutions depending on your load and precision requirements. Whether your machinery operates at a constant speed or under fluctuating loads, our belts are built to maintain stable, reliable transmission.

In terms of functionality, LSL® rubber open-end belts support a maximum width of 120mm and operate effectively within a temperature range of -20°C to +100°C. They are conditionally oil-resistant, maintenance-free, and available in custom lengths to match your specific machinery needs. Additionally, for applications that require ultra-low noise and high environmental standards, our factory also produces variants with high-quality polyurethane surfaces—a solution that's both quiet and eco-friendly.
