Family specifications and selection conditions
| 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. Also available on request with special sized bore and/or outside diameters, suitable for reworked shafts and housings. |
