Radial ball bearings provide support and alignment for rotary motion elements to run smoothly, such as a wheel on an axle. Ball bearings reduce friction which causes noise, vibration, and wear. They are found in a wide variety of equipment that have rotary motion elements such as in machine tools, pumps, motors, and conveyors.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
