    It is also based on using clean, high quality bearing steel with typical hardness levels of 58-64 HRC for rings and 60-65 HRC for balls. Based on the above, for a given bearing, a change in the pitch circle can impact the dynamic load rating, and a change in the ball diameter or ball quantity can impact both load ratings.

  • Radial Ball Bearings - Life and Load Ratings | AST

    2016-9-2 · With regard to load ratings, one thing to remember is - static load ratings (Cor) and dynamic load ratings (Cr) are formulated on completely different premises and have no direct relationship to one another. Dynamic load ratings are determined by bearing geometry number and size of balls, bearing pitch diameter, and ring and ball material.
