Ball Bearings

  • Deep Groove Ball Bearings A deep groove ball bearing is the most popular type of rolling-element bearing composed of an outer race, balls, an inner race and a bearing cage. And the race dimensions are close to balls dimensions. Usually, professional deep groove ball bearing manufacturers provide both single-row and double row deep groove ball bearings. ..
  • Angular Contact Ball Bearings Single row angular contact ball bearings are usually used in machine tool spindles, high frequency motors, gas turbines, centrifugal separators, front hub of mini vehicles, differential pinions, etc.
    Double row angular contact ball bearings are extensively used in oil pumps, roots blowers...
  • Thrust Ball Bearings Thrust ball bearings are mainly used in applications that are of low speed. They work in the axial top tight are widely used in the auto industry for vehicle clutches and the automobile steering mechanism. They are also used in oil drilling machines, machine tool spindles, lathe centers, crane hooks, lead screws, kingpin supports, speed reducers, and in rubber and plastics machinery...
  • Self Aligning Ball Bearings Self aligning ball bearings are suitable where there is a possibility of shaft deflections or misalignment due to the difficulty in accurate positioning of housing bores. This makes them suitable for long shafts.
    Self-aligning ball bearings are also used in mining machinery, heavy machinery, agricultural machinery, ventilators, railway axle boxes, power machinery as well as textile machinery.
  • Linear Ball Bearings These linear ball bearings are designed to manage a wide range of applications and load capacities. They are used in machinery and equipment which require high levels of accuracy.
    DEMY linear ball bearings are suitable for use in delicate instrumentation, industrial machines, optical and measuring equipment, food processing machines, electrical equipment...

Ball bearing is a kind of rolling-element bearings using balls to maintain the separation between the moving parts of the bearing. It can reduce the rotational friction and support radial and axial loads.
Even though it has lower load capacity than other rolling-element bearings due to the smaller contact area between the balls and races, it sells well because it can tolerate some misalignment of the inner and outer races.
And compared with other bearings, ball bearing has a lower price because the cost of producing the balls is low.
