... in the load free zone. For the MC clearance, the polyamide cage showed better behavior (less roller and rolling set slip tendency) than the brass cage contrasting the results obtained earlier under the EC clearance. It is concluded that the polyamide cage deforms under the unsymmetrical loading of the EC...
