Additive Manufacturing of Rolling Bearing Rings

<p style="text-align: center;"><img src="/ueditor/php/upload/image/20220222/1645510208102105.jpg" title="1645510208102105.jpg" alt="8.jpg"/></p><p style="text-align: justify;">Elsewhere, new manufacturing processes favor potential innovations in the field of machine elements. Additive manufacturing is a case in point: A process has been developed for selective laser melting of M50NiL steel, which is used, for example, in the high-temperature bearings of the main shaft of aircraft engines. Additive manufacturing of the outer ring allows targeted and efficient cooling of the <a href="https://www.sunspeedbearing.com/products/catalogue.html" target="_blank" style="color: rgb(0, 112, 192); text-decoration: underline;"><span style="color: rgb(0, 112, 192);"><strong>bearing </strong></span></a>(Fig.8). By separating cooling and lubrication, the weight, coolant flow and operating temperature of the bearing can be reduced and the efficiency of the engine significantly increased (Ref.11).</p>
