The Purpose of Wheel Bearings · BlueStar Inspections

The Purpose of Wheel Bearings. BlueStar Inspections. Bearings have been around since the ancient Egyptians were building the pyramids. The concept behind a wheel bearing is simple: Things roll better than they slide. When things slide, the friction between them slows them down. If two surfaces can roll over one another, friction is greatly reduced.
