Electric Motor Bearings - HECO All Systems Go

These bearings don’t require a cage and race in the same way that ball bearings do. Electric motor roller bearings are used for belted appliions with motors 150 HP and above. The surface of the cylindrical shape rolling elements helps to account for the high level of radial load that the belts put onto the bearings.
