What is a Spherical Roller Bearing? A Spherical Roller Bearing (SRB) is a bearing element that permits rotation with minimum friction and also permits angular misalignment that may occur during the working These bearings majorly find application in critical applications where they are required to support high loads- radial and axial along with the misalignment
