INSOCOAT® single row cylindrical roller bearing, NU design
Cylindrical radial Electrical insulated bearing
INSOCOAT single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. The applied electrically insulating coating on the outside surfaces of the outer or inner ring prevents electric current from passing through the bearings. 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
- Protected against electrical erosion damage
- Low friction and long service life
- Accommodate axial displacement in both directions
- Separable design
