| NC-4 Spherical Bearings Narrow - Aerospace Series, Metal to Metal
 
  Ball - 440C stainless steel (AMS 5630), heat treated, hard chrome plated (AMS-QQ-C-320 Class 2). Race - 17-4PH stainless steel (AMS 5643), heat treated. The metal to metal Spherical Bearings have the same envelope dimensions, materials (less Ptfe Liners), basic tolerances (except fit-up), as those that are approved to SAE-AS14101 and SAE-AS14104. Consult factory for material substitutions or dimensional modification possibilities. Radial Clearance is .002 max (for .0005 max, use suffix-R Example: NC-6R). For dry-film lubrication on the inside diameter of races, use suffix D(Example NC-6D). For dry film on ball bore and/or outside diameter, contact factory.
