A ball bearing is a type of rolling-element bearing that serves three main functions while it facilitates motion: it carries loads, reduces friction and positions moving machine parts. Ball bearings use balls to separate two “races,” or bearing rings, to reduce surface contact and friction across moving planes.
Some ball bearings are able to withstand a radial and axial load applied on the shaft, these combined axial/radial load bearings are achieved by axial angular contact.

These bearings have tight press fit upper and lower outer races in the frame, as well as a lower inner race that is press fit to the steering stem. The upper inner race is a little too big for me.
Because of their configuration, they have a self-aligning feature. They have two rows of balls on the inner race and a common spherical surface on the outer race, the centre of which coincides with the centre of the bearing.
