The balls and rings themselves have to be made from high performance materials; regular iron will not meet the required FDA and USDA standards. A common choice within industry is to use stainless steel balls and rings. They combine high tensile strength with good corrosion resistance and will not contaminate food. However, they are one of the most expensive options, so other materials have been designed as balls as well.

Plastic blends and can be utilized by themselves or with stainless steel, especially in plain or non-rolled style industrial bearings. Coated iron is a less expensive option as well. A chrome coating will improve the balls' hardness and corrosion resistance and increase their durability. Zinc coatings are also common for improving corrosion resistance and preventing contamination.

Bearings are important to the machines we use everyday, for without them, we would need to frequently replace broken machine parts due to the wear and tear of friction.

A bearing is a tool used to reduce the friction that occurs in machines. Bearings are categorized according to how they operate and the motions that they allow. The two common motions are linear and rotary. Bearings which allow linear motions are called linear bearings. These bearings allow motion in a straight line. An example of linear motion is the pulling and pushing of a drawer. Rotary motions, on the other hand, involve one direction rotation and oscillation, wherein the motion goes only through a part of a cycle, such as in the case of a wheel. Rotary bearings, therefore, allow motions which are concentrated on a center, like a wheel on a shaft.
