Rolling bearing comprising an inner ring, rolling elements and an outer ring. According to one aspect of the invention the inner ring is produced by M62 steel powder metallurgical technique whilst the outer ring is a conventional stool ring. According to another aspect a rolling bearing having at least one component produced by powder metallurgy technique is in a actively lubricated condition.

Rolling bearing comprising a powder metallurgical component

A stainless steel component comprising 0.8-1.4% carbon, 18-26 wt % chromium, 2-4 wt % nickel, 0-1 wt % molybdenum, 0 wt % lead and less than 0.6 wt % silicon provides for beneficial properties. Such a component may be prepared by the provision of an article from a steel starting material, and austenitizing the article between 800&deg; C. and 1050&deg; C. followed by hardening. In this process, the steel starting material comprises a powder.
