Evaluation of a High Speed, Light Load Phenomenon in ...

But as the rotational speed increases, the flowrate to the bearing is not constant. As a matter of fact, the faster the bearing runs the less flow the bearing would accept. Hence, at full speed and light load, the bearing performance is unsatisfactory with respect to the low-pressure API mechanical spin test temperature criteria.
