Since the belt tooth engages with the pulley groove without any interference, stress concentration at the root of the belt tooth can be eliminated. This belt can be used as an alternative for chains and gears. ![image\_h\_series\_timing\_belt\_construction\_en](https://www.mblusa.com/hubfs/image_h_series_timing_belt_construction_en.jpg "image_h_series_timing_belt_construction_en") ##### Construction | **Rubber** | Chloroprene Rubber | | --- | --- | | **Cord** | Glass | | **Tooth Fiber** | Nylon |   ##### Characteristics | **Heat resistance** | +90°C / +194°F | | --- | --- | | **Cold resistance** | -30°C / -22°F | | **Max belt speed** | 30 m/s | | **Electric conductive** | Yes |   H5M H8M H14M ![H5M Series Timing Belt Dimensions](https://www.mblusa.com/hs-fs/hubfs/H5M%20Series%20Timing%20Belt%20Dimensions.jpg?width=600&height=642&name=H5M%20Series%20Timing%20Belt%20Dimensions.jpg)   ![H8M Series Timing Belt Dimensions](https://www.mblusa.com/hs-fs/hubfs/H8M%20Series%20Timing%20Belt%20Dimensions.jpg?width=600&height=642&name=H8M%20Series%20Timing%20Belt%20Dimensions.jpg)   ![H14M Series Timing Belt Dimensions](https://www.mblusa.com/hs-fs/hubfs/H14M%20Series%20Timing%20Belt%20Dimensions.jpg?width=600&height=664&name=H14M%20Series%20Timing%20Belt%20Dimensions.jpg)   #### Questions?
