| has gloss | eng: Rolamite is a technology for very low friction bearings developed by Sandia National Laboratories in the 1960s. Invented by Sandia engineer Donald F. Wilkes and patented by him on June 24, 1969 these devices use a stressed metal band and counter rotating rollers within an enclosure to create a linear bearing device that loses very little energy to friction. One source claims it is the only basic mechanical invention of the 20th century. Tests by Sandia indicated that Rolamite mechanisms demonstrated friction coefficients as low as 0.0005, an order of magnitude better than ball bearings at the time. |

| has gloss | bos: Rolamit je tehnologija za ležaje sa vrlo malim trenjem koju je razvila Sandia National Laboratories tokom 1960ih. Izmislio ga je Sandiain inženjer Donald F. Wilkes, te ga je patentirao 24. juna 1969. godine. Ova sprava koristi napregnuti metalni prsten i kotrljajuće elemente koji se obrću u suprotnom smjeru, kako bi se dobio ležaj koja gubi jako malo energije na trenje. Jedan izvor tvrdi da je ovo jedno temeljno otkriće u području mašinstva u 20. vijeku . Testovi koje je provodila Sandia pokazali su da mehanizam rolamita ima koeficijente trenja čak i do 0,0005, reda veličine boljeg od kugličastih ležaja u to vrijeme. |
