Outer spherical ball bearing

Outer spherical ball bearing, also known as outer spherical bearing. It belongs to deep groove ball bearings, and the rolling element inside is a steel ball; Its outer ring surface is spherical, hence it is called an outer spherical ball bearing.
The outer spherical ball bearing is more convenient to use than the general deep groove ball bearing. Its main characteristics are simple loading and unloading, adjustable center, and the standard tolerance of the outer spherical ball bearing is: internal plus external minus, and the inner diameter adopts an additional tolerance to ensure lightness when fitting with the shaft; Each set of outer spherical ball bearings is not used separately, it must be assembled into the bearing seat as a whole, and the outer spherical bearing seat has various shapes, so it is suitable for use in various structural positions after overall matching. Outer spherical ball bearings can be divided into three categories according to the locking method with the shaft: outer spherical ball bearings with top thread, outer spherical ball bearings with taper, and outer spherical ball bearings with eccentric sleeve.
