Method for manufacturing bearing ring for roller bearing, particularly for thin-section bearing, involves rolling wire and bending wire in partial ring- or ring shape

摘要

The method involves rolling a wire (1) and bending the wire in a partial ring- or ring shape. The free ends (2,3) of two partial ring-shaped bent wires or ring-shaped bent wires are welded to a full ring (4). The full ring is annealed and cold rolled. The hardening of the full ring is followed after the cold rolling. An independent claim is also included for a roller bearing, particularly a thin-section bearing with a tread surface.
