Which of the following is self-aligning bearing?

Which of the following is self-aligning bearing? Correct Answer Spherical

Explanation:

  • A spherical plain bearing is a bearing that permits angular rotation about a central point in two orthogonal directions.
  • The outer surface of the inner ring and the inner surface of the outer ring are spherical and are collectively considered the raceway and they slide against each other.
  • The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
  • Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
