About Miniature Ball Bearings
As the name suggests, miniature bearings are very small, typically in sizes that start at 3mm with an outside diameter of 10mm. In many cases, the ball bearing size is actually less than 9.5mm in diameter. Pillow block bearings is another popular type of bearing. A thrust bearing can not only be composed of bearing balls, but other types of bearing shapes are also applicable.
