Rolamite is a technology for very low friction bearings developed by Sandia National Laboratories in the 1960s. Invented by Sandia engineer Donald F. Wilkes, these devices use a stressed metal band and counter rotating rollers to create a bearing device that loses very little energy to friction. It is considered the only basic mechanical invention of the 20th century [1]. Tests by Sandia indicated that Rolamite mechanisms demonstrated friction coefficients as low as .0005, an order of magnitude better than ball bearings at the time.
