FAQ

What does the ‘NUP’ designation mean for this SKF 2309 bearing?

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.

Can this bearing handle axial loads in addition to radial loads?

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.

What type of lubrication is recommended for the SKF NUP 2309 in a high-speed application?

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.
