SKF NU 309 ECNRJ Single row cylindrical roller bearing, NU design, with snap ring groove

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. A snap ring, fitted in an annular groove in the outer ring, facilitates axial location of the bearings within their housings. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
