SKF NU213 ECM/C3

SKF NU 213 ECM/C3 Explorer Series Bearing

Description

The SKF NU 213 ECM/C3 is a high-capacity single row cylindrical roller bearing from the SKF Explorer performance class. This bearing is designed to accommodate high radial loads and operate at high speeds. The NU design allows for axial displacement of the shaft relative to the housing, making it suitable for non-locating bearing positions.

FAQ

What is the significance of the ‘ECM’ and ‘C3’ suffixes for the SKF NU 213 bearing?

The ‘ECM’ suffix indicates an optimized internal design with a machined brass cage, which is roller-centred. This provides higher strength and is suitable for high speeds and demanding conditions. The ‘C3’ suffix denotes that the bearing has a radial internal clearance greater than ‘Normal’ (CN), which accommodates thermal expansion of the shaft and housing, preventing the bearing from seizing in applications with temperature differentials.

Can the NU 213 ECM/C3 accommodate axial loads?

The NU design, with two integral flanges on the outer ring and no flanges on the inner ring, is designed to accommodate axial displacement of the shaft relative to the housing in both directions. However, it cannot locate the shaft axially and is not intended to support axial loads. For combined radial and axial loads, you would need a different bearing type, such as an angular contact ball bearing or a spherical roller bearing.

What type of lubrication is recommended for the NU 213 ECM/C3 in a high-speed application?

For high-speed applications, oil lubrication is generally preferred over grease as it provides better cooling and contaminant removal. The specific oil viscosity would depend on the operating temperature and speed (nDm value). It is crucial to consult the SKF lubrication guidelines or use their calculation tools to select the appropriate lubricant to ensure optimal bearing life and performance.
