Roller Bearings vs. Ball Bearings - What''s the Difference?

Roller bearings perform better under shock and impact loading. Ball bearings are usually sold as asselies and are simply replaced as units. Roller bearings can often be disasseled and the roller carrier and rollers, or the outer or inner races, replaced individually. Rear-wheel-drive cars use such arrangements for the front wheels.
