Hybrid ceramic single row cylindrical roller bearing, NU design

Hybrid ceramic single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds.

With rings made of bearing steel and rollers made of bearing grade silicon nitride, the bearings are electrically insulating. The ceramic rollers not only protect against electric current damage, but also extend bearing service life by offering enhanced bearing performance, even under difficult operating conditions. 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. The separable design facilitates mounting and enables the bearing components to be interchanged.

  • High radial load carrying capacity
  • Protected against electric current damage
  • Low friction and long service life
  • Accommodate axial displacement in both directions
  • Separable design
