How to Select the Most Suitable PU Timing Belt Based on Core Material?

In automated equipment design, the selection of transmission components is critical. As a high-performance transmission belt, the core material within a polyurethane timing belt is the key factor determining its performance orientation and application scope. Understanding the characteristics of different cores is the first step toward making the right choice.

Core: The “Skeleton” of PU Timing Belts

The outstanding properties of polyurethane timing belts—corrosion resistance, aging resistance, wear resistance, and low noise—make them an ideal choice for high-end transmission applications. However, their true “soul” lies in the core material.

Kevlar Core: The Flexible Choice

PU timing belts with Kevlar cores offer exceptional bending performance, making them highly suitable for compact transmission systems requiring small-diameter pulleys. Their flexibility ensures long-term durability under frequent bending, though their tensile strength is relatively weaker compared to steel cord cores.

Steel Cord Core: The Power Choice

PU timing belts with steel cord cores excel in exceptional tensile strength. They can withstand higher loads, making them suitable for applications requiring significant power transmission. Their drawback is a larger bending radius and less flexibility than Kevlar cores.

Precise Selection for Efficient Transmission

Beyond the core material, matching the tooth profile and specifications is equally critical. Incorrect selection can lead to tooth skipping, wear, or even equipment failure. Therefore, when purchasing PU timing belts, ensure you provide the following parameters: tooth profile, length, width, and coating thickness if required.
