Technical compliance


Like the majority of the well-known bearing manufacturers, FV chooses to strictly follow the standards defined by ISO for a reliable life calculation of rolling bearings.
All FV's calculations of load rating capacities rigorously apply the regulations set by ISO 281:2007, ISO/TR 1281-1:2008, ISO/TR 1281-2:2008, and ISO 76:2006 in their latest revision. In fact, ISO method for rolling bearings is the sum of today's universally recognized, proved and standardized knowledge, development and information, that yield satisfactory results (appropriate and convenient substitute for testing).
This enables FV to exploit bearing life potential with a proper safety index, to undertake controlled sizing and to take into duly consideration the complexity of theory with proved criterions on metal fatigue of rolling contact surfaces.
Evidences from R&D with a bottom-up approach are not considered to modify ISO method with the adoption of unilaterally revised empowered factors, formulas and tables.
