• Synchronous Belts DEMY synchronous belts have exact transmission ratio and no slippage. And constant velocity and smooth motion can be obtained for its toothed design. Additionally, they can help absorbing vibration and feature with low noise.
    A high transmission efficiency of 98% is available. ..
  • Conveyor Belts There are different kinds of conveyor belts for different uses. Classifying by construction materials, we can obtain belts made of PVC, PU, PE, nylon, general fabric and stainless steel, etc. Classifying by applications, we can obtain oil-resistant belts, flame-retardant belts, corrosion-resistant and thermal-resistant belts, and more. ..
  • V-Belts V belts (also known as vee belts or wedge ropes) has been the most popular type driving belt for power transmission.
    Vee belts have wide range of specifications, including Y, Z, O, A, B, C, D, E and so on.
    A, B, C, D and E vee belts are primarily used for heavy-load operations. ..
  • Automotive Timing Belts Our automotive timing belts feature with low-noise operation, lubrication-free, no slippage and super high mechanical efficiency. They also feature with good economy for their good fuel-conservation capability. ..

A belt can be used to link two or more rotating shafts. Also it can be used as a source of motion to transmit power efficiently or to track relative movement.
It is looped over pulleys. In a two pulley system, in order to ensure that the direction of the shafts is opposite, the belt can either drive the pulleys in the same direction, or the belt may be crossed. Conveyor belt can carry a load between two points continuously.
Ningbo Demy (D & M) Bearings Co., Ltd. is a professional belt manufacturer in China. We mainly produce various belts, bearings, chains, hardware spare parts and other mechanical and electrical products. To meet the requirements of our customers, we can provide a wide range of belts, such as synchronous belt, conveyor belt, V-belt, automotive timing belt and so on. These belts are used in many fields like shipbuilding, heavy-load operation, and transmission system, etc. They are easy to maintain and have high transmission efficiency. So our products have passed ISO9001:2000 quality management system certification and are sold to America, France, Germany, Philippines, and Australia, etc.
We would like to expand our business line to more countries and regions. So please contact us if you are interested in our products.
