Anti-friction bearing cage manufacturing method, involves laying cage halves around shaft section i.e. bearing journal, such that cage halves form cage ring, and molding cage ring with closed plastic casing

摘要

The method involves manufacturing two cage halves (2, 4), and laying the cage halves around a shaft section i.e. bearing journal, such that the cage halves form a cage ring. The shaft section with the cage ring is inserted into a plastic spraying tool. The cage ring is molded with a closed plastic casing (6). Recesses are formed for retaining a roller body (8) by a slide-gate valve. The cage halves are made of metal. An independent claim is also included for a device for manufacturing an antifriction bearing cage for an anti-friction bearing arranged on a single-piece and a bent shaft.
