  • Body - Low carbon steel, protective coated for corrosion resistance.
  • Ball - Alloy steel, heat treated, hard chrome plated.
  • Race - Low carbon steel,protective coated for corrosion resistance.
  • Units are traceable and are magnetic particle inspected after assembly.
  • Grease Fitting available for all sizes. Units are supplied without grease fittings. When a grease fitting is required, specify by adding suffix "Z" or "F". Ex.: GMM-3MZ-470 = Zerk Type Fitting GMM-3MF-470 = Flush Type Fitting.
  • Load ratings apply only to rod ends without grease fittings. For load ratings with fittings, consult our engineering department.
  • For rod end bearings which are non-traceable or non-magnetic particle inspected, consult factory.
