The choice of the bearing is essential for a highly prepared motor, at high speed the bearings enter vibrations even if it does not feel it necessarily! These various vibrations create a force and thus brakes the crankshaft! In addition, a very powerful engine between torque and high speeds can literally explode the bearing! Here are the reasons why I propose this POLINI competition race! Used for the competition it is ultra resistant from the ball to the cages.
He will bring you:
Better rolling lubrication thanks to its architecture
Less vibrations thanks to its studied polyamide cage
Resistance out of the common thanks to a studied game and the most resistant materials of the world
Even an excellent aesthetic with its engravings POLINI evolution
They are normal bristles for MINARELLI AM6 engine, so they are mounted on the original crankshaft and all competition crankshafts using a silk original size. Manufactured at SKF specifically for POLINI MOTORI.
