NU 1008 ML/HC5C4
Single row cylindrical roller bearing, NU design
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.
- High radial load carrying capacity
- Low friction
- Long service life
- Accommodate axial displacement in both directions
- Separable design
