The objective of these analyzes is to evaluate the behaviour of bearing cage in operation and to determinate the safety factor towards to yield and ultimate strength of structure, when cage is under load. Safety factor can be defined as force needed to achieve yield or ultimate strength divided by operation force given from dynamic simulation. Second analyze was based on pressing of whole cage in radial direction to determinate radial pressing force needed to achieve yield and ultimate strength.
