With downward pressure applied, the bearing assembly becomes immersed into the thick grease which squeezes into all gaps between the bearings, cage, and race.

Ball bearings – These are perfectly round metal balls. While they're used in some automotive bearing assemblies , they are more commonly found in skateboards, electric motors, and household machinery. Because their spherical shape allows them to spin in any direction, they can handle both radial loads (weight from above) and thrust loads (sideways force). However, perfectly round ball bearings have a very small contact area. This limits them to light-to-medium applications and to locations on a vehicle that are not subject to heavy pressure and shocks from road impacts.
