NU design bearings have two integral flanges on the outer ring and no flanges on the inner ring. They are able can accommodate axial displacement of the shaft relative to the housing in both directions. NU design bearings can be used together with an appropriate angle ring to stabilize the bearing in the axial direction . Features: Low friction (Roller end / flange contact area) - The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity. Long service life - The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection. Enhanced operational reliability - The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film. Separable and interchangeable - The separable components of SKF cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections. High speed capability - The cage designs are suitable for high speeds, rapid accelerations and peak loads. Specifications: Dimension Standards: Boundary dimensions: ISO 15. HJ angle rings: ISO 246.
