Original DH Belt Supplier in China
The DH belt is a double-sided timing belt with trapezoidal teeth on both sides. This allows for bidirectional meshing and improves the stability and accuracy of synchronous transmission.
Compared with a trapezoidal timing belt with teeth on only one side, DH belt can achieve higher transmission efficiency in a more compact space. In addition, its two tooth surfaces can evenly distribute the load, which can effectively reduce the vibration and noise of your equipment during operation and ensure stable and synchronous transmission of the equipment.
DH Belt Provides You with Double-Sided Synchronous Drive
ZQDrive DH belt features teeth on both sides, precisely meshing with pulleys and providing precise synchronous transmission of the upper and lower belt drive surfaces. This design can be used for double-sided drive or multi-axis transmission, which can evenly distribute the load and reduce transmission errors, while running quietly and requiring almost no maintenance.
The load capacity, pitch, and tooth profile of DH belt are the same as those of the corresponding model of single sided timing belt. Compared to single drive timing belts, it also offers greater flexibility in bidirectional drive within limited spaces, ensuring smooth and precise operation for your equipment.


DH Belt Improves the Transmission Efficiency of Your Equipment
DH belts offer higher transmission efficiency than conventional drive belts. They can efficiently and stably transfer power from the driving pulley to the driven pulley, reduce energy loss, and improve the energy utilization efficiency of your equipment. ZQDrive DH belts are suitable for applications where the direction of rotation can be changed and can achieve precise transmission. They are widely used in printing machinery, packaging machinery, medical equipment, textile machinery, office equipment, and other fields.
Your Space Saving DH Belt Drive Solution
DH belts have double-sided teeth and can support co-rotating and counter-rotating transmission systems. This design can save installation space, make the transmission system more compact and flexible, and improve your equipment’s transmission efficiency by up to 98%. In addition, ZQDrive DH belts have the advantages of low noise, oil resistance, heat resistance, lubrication free, and aging resistance. They are suitable for applications that require compact space and bidirectional drive, providing your equipment with stable, efficient and compact power transmission.

ZQDrive supports customized DH belts. We have common DH belt width specifications, including 19.1 mm, 25.4 mm, etc. In addition, we offer custom options for width, length, material, packaging, and more to meet your specific needs.
DH belts have good high temperature resistance and can be used in conditions of -30°C ~ +100°C. Some high temperature resistant materials can even withstand temperatures of 120°C.
The main components of the DH belt include tooth facing, tension member, and synthetic rubber belt body. The wear-resistant tooth facing protects the teeth of DH timing belt from wear and tear. The tension member has flexibility and high tensile strength, and is responsible for bearing the tension and ensuring the stability of the DH belt. The belt body is made of synthetic rubber, which is resistant to heat, oil, moisture, and aging.
