High radial capacity for demanding machinery

Practical benefits

Built for heavy loads: The NU 307 ECP/C3 cylindrical roller bearing accommodates high radial forces while maintaining smooth, high-speed performance.
Enhanced thermal clearance: With C3 internal radial clearance, you prevent overheating and compensate for thermal expansion during intensive use.
Easy and fast installation: The separable design enables you to mount and dismount inner and outer rings independently.

In a nutshell

The right choise for

With the Skf nu 307 ECP/C3 single row cylindrical roller bearing, you reliably support heavy radial loads across demanding industrial machinery, electric motors, and gearboxes. Thanks to its increased C3 radial internal clearance, the bearing easily compensates for thermal expansion during continuous, high-speed operation, preventing unwanted internal preloading. The nu design features integral flanges on the outer ring, allowing smooth axial displacement of the shaft in both directions. In addition, the lightweight polymer cage ensures low friction and stable rotation. Its separable design makes mounting, inspection, and maintenance remarkably fast and straightforward.

Product description

Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and no flanges on the inner ring, NU design bearings can accommodate axial displacement in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
