Deep groove ball bearings

  • The most popular types among rolling bearings, widely used in a variety of industries.
  • Radial load and axial load in both directions can be accommodated.
  • Suitable for operation at high speed, with low noise and low vibration.
  • Sealed bearings employing steel shields or rubber seals are filled with the appropriate  volume of grease when manufactured.Angular contact ball bearings

    Self-aligning ball bearings

    • Bearing rings and balls possess their own contact angle that is normally 15, 30 or 40.
      Larger contact angle — higher resistance against axial load
      Smaller contact angle — more advantageous for high-speed rotation
    • Single-row bearings can accommodate radial load and axial load in one direction.
    • DB and DF matched pair bearings and double-row bearings can accommodate radial load and axial load in both directions.
    • DT matched pair bearings are used for applications where axial load in one direction is too large for one bearing to accept.
    • Angular contact ball bearings are used for high accuracy and high-speed operation.
  • Spherical outer ring raceway allows self-alignment, accommodating shaft or housing deflection and misaligned mounting conditions.
  • Tapered bore design can be mounted readily using an adapter.Cylindrical roller bearings
  • Since the design allowing linear contact of cylindrical rollers with the raceway provides strong resistance to radial load, this type is suitable for use under heavy radial load and impact load, as well as at high speed.
  • N and NU types are ideal for use on the free side: they are movable in the shaft direction in response to changes in bearing position relative to the shaft or housing, which are caused by heat expansion of the shaft or improper mounting.
  • NJ and NF types can accommodate axial load in one direction: and NH and NUP types can accommodate partial axial load in both directions.
  • With separable inner and outer ring, this type ensures easy mounting.
  • Due to their high rigidity, NNU and NN types are widely used in machine tool spindles. Tapered roller bearings
  • Single-row bearings can accommodate radial load and axial load in one direction, and double-row bearings can accommodate radial load and axial load in both directions.
  • This type of bearing is suitable for use under heavy load or impact load.
  • Bearings are classified into standard, intermediate and steep types, in accordance with their contact angle.
  • The larger the contact angle is, the greater the bearing resistance to axial load.
  • Items sized in inches are still widely used.  Spherical roller bearings

    Needle roller bearings

    • Spherical roller bearings comprising barrel-shaped convex rollers, double-row inner ring and outer ring are classified into three types: R(RR), RH(RHR) and RHA, according to their internal structure.
    • With the bearing designed such that the circular arc center of the outer ring raceway matches with the bearing center, the bearing is self-aligning, insensitive to errors of alignment of the shaft relative to the housing, and to shaft bending.
    • This type can accommodate radial load and axial load in both directions, which makes it especially suitable for applications in which heavy load or impact load is applied.
    • The tapered bore type can be easily mounted/dismounted by using an adapter or withdrawal sleeve.
  • In spite of their basic structure, which is the same as that of NU type cylindrical roller bearings, bearings with minimum ring sections offer space savings and greater resistance to radial load, by using needle rollers.
  • Bearings with no inner rings function using heat-treated and ground shafts as their raceway surface. Thrust ball bearings
  • This type of bearing comprises washer-shaped rings with raceway groove and ball and cage assembly.
  • These bearings cannot accommodate radial loads.Spherical thrust roller bearings
  • This type of bearings, comprising barrel-shaped convex rollers arranged at an angle with the axis, is self-aligning due to spherical housing washer raceway; therefore, shaft inclination can be compensated for to a certain degree.
  • Great axial load resistance is provided.
    This type can accommodate a small amount of radial load as well as heavy axial load.

KOYO self-aligning ball bearings is widely used in indistries. In this article I will make a brief introduce of it on behalf of China BRG bearing, who is one of the world leading KOYO bearings distributor in China.

KOYO self-aligning ball bearings have a spherical outer ring raceway, the center of whose curvature meets that of the bearing itself, so that the inner ring, ball and cage continue to rotate, aligning themselves if they have become misaligned within design limits.

This type of bearing is suitable when the displacement of the centers around which the shaft and housing rotate and shaft deflection are likely to occur. Bearings with a tapered bo re can easily be fit to the shaft with an adapter assembly.

Some of KOYO self-aligning ball bearings sold well in the world:
