Product structure | ||
01, neoprene belt body | Has good oil resistance, heat resistance and anti-aging properties | |
02, glass fiber tension | Has high strength, good flex resistance and low elongation | |
03. Tooth surface nylon cloth | Has the wear resistance and shear strength of teeth | |

Circular arc tooth |
Performance characteristics: |
Suitable for high-power and high-torque transmission √ |
Its transmission power is 3-5 times larger than trapezoidal toothed belt wheel√ |
Rotation speed is mainly low and medium speed √ |

Trapezoidal tooth |
Performance characteristics: |
General industrial transmission √ |
Suitable for small and medium power transmission √ |
Larger linear speed can be used for higher speed transmission √ |
