Defects of Polyurethane Timing Belts

Friends who often use polyurethane timing belts for transmission will know that it has the following transmission characteristics (or advantages) like other timing belt transmissions:

1. Accurate transmission, suitable for high-speed operation, and high transmission efficiency;

2. Easy maintenance, no need to add lubricating oil, can keep the machine clean;

3. The transmission structure is compact, the weight of the synchronous belt is light, the thickness of the belt is thin, and the flexibility is good, which can reduce the weight of the transmission mechanism;

4. Small impact, large speed ratio, large load range, and low operating noise, etc.

The polyurethane timing belts we produce also have physical and chemical characteristics such as good wear resistance (no powder drop), anti-aging, anti-ultraviolet UVA, anti-ozone, highly oil-resistant, and anti-corrosion of most acids and alkalis. After we have learned about the excellent performance characteristics of so many PU timing belts, are you curious whether there are no shortcomings in polyurethane timing belts? The answer is no, polyurethane (PU) timing belts are not perfect and unbeatable.

The disadvantages of polyurethane timing belts are:

1. Compared with rubber materials, polyurethane is not resistant to water;

2. Polyurethane (PU) synchronous belt generates large internal heat after multiple flexing;

3. Poor high and low temperature resistance, the temperature range used is: -5 °C ~ 80 °C, and the instantaneous temperature can withstand 110 °C.
