Lower Operating Temperature is one of the greatest benefits of CERBEC® Balls because lubricant life can be extended or speed can be increased. Lower Operating Temperature results from CERBEC's: lighter weight (lower frictional losses) higher stiffness (lower contact area with metal race reducing friction) inertness (no adhesive wear or heat generation from micro-welding) lower thermal expansion (stable pre-load & contact angle reducing friction) As shown in the chart, at all speeds, bearings run cooler with CERBEC balls allowing for longer life or higher speed.
