INSOCOAT NU type single row cylindrical roller bearings

INSOCOAT single row cylindrical roller bearings are designed for applications subject to heavy radial loads and high speeds. An electrically insulating coating applied to the outer surface of the inner or outer ring prevents current from passing through the bearing. NU-type bearings with integral flanges on both sides of the outer ring and no flanges on the inner ring allow bi-directional axial displacement. An important feature is the separable design, which facilitates mounting, and the individual parts of the bearing are interchangeable.

  • High radial load carrying capacity
  • Protection of the bearing against galvanic corrosion damage
  • Low friction
  • Long service life
  • Can withstand bi-directional axial displacements
  • Separable design
