Moroccan national rail operator, Office Nationale des Chemins de Fer du Maroc (ONCF) awarded SKF a three-year contract to supply railway wheelset bearings.
Under the contract, SKF will deliver 15,000 railway wheelset bearings over a period of three years for both passenger and freight rolling stock.
The units being delivered to ONCF include SKF’s spherical roller bearings (SRBs) which are typically applied as sets of two double-row bearings in a configuration where the two rows of rollers share a common spherically profiled raceway in the outer ring and the two inner raceways are inclined at an angle to the bearing axis. Single spherical roller bearings are also deployed in axleboxes to gain greater design flexibility. In both cases, these bearing configurations are highly tolerant of misalignment and shaft deflection.
SKF railway certified SRBs have a higher load carrying capacity which is of particular benefit to heavy freight carrying rolling stock applications. Moreover, the new cage design of these bearings ensures higher reliability and longer service life, as well as greater tolerance of the high temperatures and harsh climatic conditions that are typical on this continent.
