High-speed bearings with increased load capacity, designed and tested for endothermic racing engines. Special high-speed precision bearings, reinforced for increased load and heavy applications, with oversize balls, carbonitrided inner rings, steel and polyamide cages. The co-operation of Malossi technicians with the company SKF allowed to obtain an important technical result for the fi ne-tuning of high-quality racing engines. Above all, we would like to point out bearing art. 6614105EA, since it features - besides the carbonitrided ring - reinforced load capacity, polyamide cage and reduced outer ring tolerance. This last modification was made by Malossi technicians to achieve a better lubrication of the ball guides.
