A method of making a bearing component comprising the steps:
- forming an elongated metallic strip into a circular tubular ring with the opposite end edges of the strip being brought into confrontation and fused together,
- forming the ring into a frustoconical configuration with one edge of the ring defining a small circumference and one edge of the ring defining a large circumference and with the ring retaining the original circular ring diameter,
- flattening the frustoconical configuration into a single plane and turning the opposite edges of the flattened ring in planes normal to the plane of the flattened ring and in parallelism with each other.
