What makes a good bearing? Last Updated: 03/23/2011
There are several factors that make a good bearing or a correct working bearing. 1. Free Rolling with minimal Radial Play (which reduces the ball to ball load transfer). 2. Plenty of Axial Play or Axial Thrust. This is what allows a Roller Skate Bearing to work well. The tighter Axial tolerances of a higher ABEC Rating is not always what is needed for Roller Skating.
