What Is Dynamic Load Rating?
The dynamic load rating (C) is the most important catalogue value for bearing selection. Defined by ISO 281, it represents the constant radial load under which a bearing achieves a basic rating life of 10^6 revolutions. It is used directly in the L10 life calculation: L10 = (C/P)^p.
Frequently Asked Questions
What is the dynamic load rating of a bearing?
It is the constant, unchanging radial load (in kN) under which a group of identical bearings with stationary outer ring would achieve a basic rating life of one million revolutions of the inner ring. A higher C rating means the bearing can handle heavier loads or last longer at the same load.
