Q18. What is a Spherical Bearing?

A "spherical bearing", as the name implies, is a bearing that is composed of a raceways that are rounded (spherical) on the inside axially (in addition to the normal radial curvature of course).  However, there are many different types of spherical bearings including:

  • Spherical ball bearings (a.k.a. double-row, self-aligning ball bearings)
  • Spherical roller bearings (a.k.a. double-row, self-aligning roller bearings)
  • Spherical plain bearings (a.k.a. ball busings)
  • Rod ends (a.k.a. spherical rod end bearings)

The one thing they all have in common besides spherical raceways is that they all are designed to accomodate shaft misalignment.  To learn more, go to our webpage entitled, "Spherical Bearings – Accommodating Misalignment" at www.ASTBearings.com/spherical-bearings.html
