Bearings / Ball Bearings

Ningbo DEMY (D & M) Bearings Co., Ltd is one of the leading manufacturers of ball bearings, roller bearings, and other types of bearings. We are also an exporter and distributor of a variety of belts, chains, auto parts and hardware spare parts, etc.

Ball bearings and roller bearings are rolling-element bearings used for supporting loads, both axial and radial. They are a necessity in almost every industry. For example, deep groove ball bearings are used to reduce rotational friction in gearboxes, electrical motors, and in textile industries, while angular contact ball bearings and tapered roller bearings are regularly used in machine tool spindles, wheel hubs of vehicles, and more.

With bearings being so important in so many industries, we decided to specialize in bearing manufacturing. We started DEMY with 8 million dollars, to acquire advanced production equipment and recruit skilled technicians. Since our beginning, we have been committed to providing our customers with bearings which are of high precision, low noise, and long service life. Additionally, we have expanded our manufacturing range to satisfy increasing market demands. Now we can provide not only ball bearings and roller bearings, but also wide array of auto bearings, insert bearings, joint bearings, cam follower bearings, and more.

Of course, we found that many customers need not only bearings, but also chains and belts for their machinery. In order to provide more convenience to our customers, we now also supply a wide variety of belts and chains, which run over pulleys, sprockets, or sheaves. Conveyor belts, synchronous belts, conveyor chains, and roller chains are among our most popular products.

DEMY's products now are ISO9001:2000 certified and have been well-accepted in Europe, South-east Asia, the Middle East, South America, etc. In order to better serve our national and international customers, we have established a complete after-sales-service system. We can also customize products, upon request.

We look forward to helping you with your bearing, belt and chain needs.
