 · Ball bearings are described as having point contact; that is, each ball contacts the race in a very small patch – a point, in theory. Bearings are designed such that the slight deformation the ball makes as it rolls into and out of the load zone does not exceed the yield point of the material; the unloaded ball springs back to its original shape. Ball bearings do not have

 · Iron balls like these were and still used by "ball mills" to crush mined ore. A large drum is filled with ore and iron balls and then tumbled to pulverize the ore to powder (part of the reduction/ refining process). Here in Colorado a lot of these are mistaken as "cannon balls", however most are left over from the mining days. Link to comment Share on other sites. More
