What's the difference between a spherical and a conical ball bearing?
assistant
A spherical ball bearing has a round outer surface, while a conical ball bearing has an inner cone shape. Spherical bearings are designed to provide greater radial clearance than conical bearings, so they can move more easily. Conical bearings have better angular contact with the raceway than spherical bearings, which helps them maintain their position in the raceway.
