Roller Bearings

  • Tapered Roller Bearings Tapered roller bearings can be used for applications that involve axial loads, radial loads or combined loads.
    For example, they are often used in vehicle front and rear wheels where they cope with large radial and axial forces, gear shafts, transmissions, machine tool spindles, construction...
  • Cylindrical Roller Bearings Specifically, our cylindrical roller bearings can be used in industrial transmission, automotive, electric motor, generator sets, elevating machinery, machine tool spindles as well as internal-combustion engines, etc.
    These roller bearings can be separated and are easy to mount as well as dismount.
  • Spherical Roller Bearings Our spherical roller bearings are suitable for applications involving heavy and impact loads hence can operate under extreme conditions. Specifically, they can be used in metallurgy, molding machines, paper making machinery, crane hooks, conveyors, construction machinery, large machinery, vertical pumps, shakers, speed reducers, and industrial gear boxes, etc.
  • Needle Roller Bearings They can be used in tasks with limited radial space and can endure heavy loads. Specifically, needle roller bearings are widely used in numerous engine components such as transmissions, rocker arm pivots, compressors, pumps. Also in steering and braking systems, power tools, fax machines, copier machines.

A roller bearing is a kind of bearing carrying a load by placing round elements between the two pieces. The relative motion of the pieces causes the round elements to roll, and there is little rolling resistance and little sliding during this process.
Our roller bearing is applicable to transmissions, electric motor, and construction machinery, etc.
Ningbo Demy (D & M) Bearings Co., Ltd is one of the most important roller bearing manufacturers. We mainly deal with tapered roller bearing, cylindrical roller bearing, spherical roller bearing and needle roller bearing. These roller bearings have been ISO9001:2000 certified and extensively used in America, Philippines, France, Germany, Spain, Malaysia, and more.
