  • Bearing Materials
    Bearings materials are classified as through-hardened materials (used largely for ball bearings) and case-hardened materials (used largely for roller bearings). Critical applications require vacuum-processed steels. Regardless of material type, a commonly accepted minimum hardness for bearing

     . 7/8/2010 .  .  .  .  . Historically, one of the more common linear guidance systems used has been bearing blocks containing re‐circulating ball . bearings running on profiled steel rails that are fastened to a structure.  In recent years, PBC Linear has introduced another . type of linear guidance
