FAQ

The 'NUP' designation indicates that the bearing has two integral flanges on the outer ring and one integral flange plus a loose flange ring on the inner ring. This design allows the bearing to locate the shaft axially in both directions.

Yes, the NUP design is specifically intended to handle light to moderate axial loads in both directions, making it suitable for locating a shaft. However, its primary function is to support heavy radial loads.

For high-speed applications, oil lubrication is generally recommended over grease. The specific viscosity and type of oil should be selected based on the operating temperature, speed, and load conditions, as detailed in the SKF engineering manual.
