CNN high temperature bearings and bearing units are designed to deliver increased reliability, reduced complexity and decreased environmental impact in operating temperatures up to 350 °C (660 °F). Because CNN high temperature bearings correspond to the ISO dimensions of grease-lubricated bearings, production efficiencies and cost savings can be realized with a simple change to the CNN bearing solution.

The environmental benefits of CNN high temperature bearings are so significant in many applications that they are included in the “CNN Beyond Zero” product portfolio.

Bearing benefits and features

  • Reduced total operating cost
    The bearings are designed to maintain the radial clearance needed for high temperature operation and so will not seize, even when they cool rapidly, and therefore provide a long service life.
  • Virtually maintenance-free operation
    The bearings are lubricated for life and do not need relubrication. Only variant VA201 without shields requires relubrication.
  • Excellent performance under severe conditions:
    • hot conditions
    • dry environments
    • low rotational speeds
  • Reduced environmental impact
  • Reduced machine design complexity
