ABSTRACT:
A cage for a high speed anti-friction roller bearing having an improved design in which the openings therein have all four sides thereof formed of a convex configuration and join each other at concave corners of relatively large radii. By establishing an acceptable or initial roller skew angle based upon roller and guide rail design, the internal configuration of the cage is designed such that contact by the rollers at the corners of the cage will not occur until after wear between the rollers and the guide rails has developed to such an extent that the accptable skew angle of the rollers has been exceeded. Consequently, spalling or wear debris can be detected prior to roller-cage corner contact and probable catastrophic roller bearing failure can be prevented.
