A brand elaborated by a group of producers using very advanced technical know-how and highest technology machineries. Its production envolves all standard bearings schedules: for special technical or constructive requirements a staff of competent technicians works to satisfy every problem about design and utilisation. We are introducing the complet program of basic ISB® bearings production. The purpose of this catalogue is to create a kind of real help for machineries' and equipments' designers: a valid contribution to the reasearch of the best bearings' application; a clear elucidation for technical, dimensional, qualitative and applicative characteristics. The first part of it showes the technical details of every bearing, such as dimensional tolerances, radial clearance, lubrication and some other informations concerning the choice and the type of bearing to use. The second part of it, instead, is dedicated to bearings tables. In these tables all bearings are classified with regard to kind of contruction and diameter of bore. All technical constructive characteristics have been determined in accordance with national standard of ISO in order to provide an interchangeable product, steady during the years and of high quality.
