Rolling bearings, belts, oil seals - ROMBOR »
Initially, rolling bearings were used very rarely due to problems with precise machining of parts, especially rolling elements. It was not until 1883 that the construction of the machine tool allowed for cheap and mass production of steel balls. As a result, it was possible to manufacture industrial bearings, and later automotive bearings. We invite you to familiarize yourself with the offer of our company, which has been built since 1990. We sell all types of bearings, as well as drive belts and lubricants.
