Case Carburized, Longer Lasting The case carburization process creates bearings with a hard, wear resistant outer shell and a tough, ductile core. The tough outer shell helps protect the rolling elements from debris, while the ductile core allows the bearing to both absorb increased shock loading and operate under misalignment without failing. These traits are critical in heavy-duty applications, in which bearings are forced to operate in demanding environments. Every premium Bower bearing is case carburized for optimal, long-lasting performance.
