Advantages and disadvantages analysis of TPU timing belt and CPU timing belt

Mar.25.2025

1. Application and advantages and disadvantages of TPU timing belts

TPU timing belt (thermoplastic polyurethane timing belt) is mainly used in industries with high hygiene requirements, especially in the food, pharmaceutical and electronic fields. This is due to the fact that TPU materials are dust-free and easy to clean, and are able to meet the stringent hygiene standards required by these industries. In addition, TPU timing belts are also commonly used in medium load linear transmission equipment, such as ceramic conveyor belts, packaging machinery, glass conveying equipment.

Advantages: good hygiene, wear and chemical resistance, light load transmission, disadvantages: low tensile strength, limited scope of application.

2. CPU timing belt applications and advantages and disadvantages

CPU timing belt (polyurethane timing belt) is widely used in the field of high-precision power transmission, especially in automation equipment, CNC machine tools and other demanding industries. Due to its seamless design, it can effectively reduce transmission errors and ensure the precision of equipment. In addition, CPU timing belts are also suitable for mechanical equipment with frequent starting and stopping or high load, such as high-speed transmission machinery.

Advantage:High precision power transmission, strong fatigue resistance, adapt to harsh environments

Disadvantage:Higher manufacturing cost: Compared with rubber timing belts, the manufacturing cost of CPU timing belt is higher, which increases the overall purchasing cost.

Strict storage requirements: need to be stored in a constant temperature, dry environment, otherwise prone to color changes and other problems, storage requirements are higher compared to rubber timing belts.

In the actual selection, TPU timing belt is suitable for the occasions that require high cleanliness and hygiene and light load, especially in the food and pharmaceutical industries are very widely used. While CPU timing belts are more suitable for occasions that require high precision and high load, such as automation equipment and high-precision mechanical transmission. CPU timing belts perform better in industries with high budget requirements and harsh working environments. The final choice should take into account the load demand, working environment and budget and other factors. Based on these factors, you can make a more appropriate choice to ensure the long-term stable operation of the equipment!
