Triple lip seal contacts with the stainless steel flinger, not the shaft or inner ring. Constant seal pressure in misaligned conditions
The grease in CX2SN bearing purges depending on the speed of application. As the RPM’s increse this seal allow the excess grease to excape allowing it to run at lower temperatures.

SEAL

The seal lip rubs against the shaft which leads to damage to the shafting.  Diminished seal pressure can also occur when there is misalignment.
The SN bearing has a larger void meaning more grease is needed. The seal design of the SN bearing does not allow excess grease to purge easily meaning that it continually runs at a higher temperature.
