Have you ever wondered how ball bearings were made, then check out this “How it’s made” segment showing you how those ball bearings construct. Video after the jump.

Ball bearings typically support both axial and radial loads and can tolerate some misalignment of the inner and outer races. A radial ball bearing uses axially symmetric inner and outer races that are shaped so a radial load passes radially through the bearing while the axial ball bearing uses side-by-side races. An axial load is transmitted directly through the bearing, while a radial load is poorly-supported, tends to separate the races, and anything other than a small radial load is likely to damage the bearing.
