Abstract:
A roller bearing cage in which a cylindrical cage is split along a diametral plane thereof into a pair of two semicircular cage halves that are arranged in opposition to each other with their mating ends coming into abutment against each other: comprising that the semicircular cage halves are each composed of semicircular rims arranged in a way spaced axially apart from each other and extended circumferentially in parallel with each other, and cage bars positioned between the semicircular rims at regular intervals around curved surfaces of the rims and made integrally with the rims to form pocket between any two adjacent cage bars, in which a roller is accommodated for rotation; the semicircular cage halves are chamfered off at outer peripheral areas nearby the mating ends thereby to form chamfered even areas;wherein the chamfered even areas on the outer peripheral areas are approximately normal to the mating ends of the semicircular cage halves and also lying on planes that extend in parallel with each other in diametral opposition.
