Ball bearing manufacture process involves bending edges of sheet metal strip to form shallow U-section which is wrapped around outer race of bearing, welded and then welded to mounting flange
The ball bearing has a normal inner race (4), balls (6) and a normal outer race (5). The edges (2) of the sheet metal strip are bent, and the strip is wrapped around the cylindrical outer surface (7) of the outer race. The bent edges face inward. The ends butt together and are welded together. The ends of the strip may be plain or may be dovetailed to positively interlock. A mounting flange (11), with through bores (13) to accommodate fastening bolts, is then welded (14) to the strip adjacent to one edge.
