Ball - 52100 steel (AMS 7440), heat treated, hard chrome plated (AMS-QQ-C-320 Class2).
Race - alloy steel, heat treated.
Liner - AT 3200 bearing liner, permanently bonded to race inside diameter. Qualified to SAE-AS81820.
Spherical bearings listed in tables below are shown with SAE-AS81820 Ptfe liners. These bearings are available less the Ptfe liners. Omit "T" from the suffix in the part number (ex.: HAB-6-500).
For non-Ptfe lined units the radial clearance is .002 maximum. For .0005 maximum radial clearance use suffix "R" (ex.: HXAM-6RM-500).
Staking groove style bearings are available. Consult factory for dimensions and staking groove data.
For dry film lubrication on inside diameter of races, use suffix "D" (ex.: HAB-6D-500). For dry film on ball bore and/or ball outside diameter, consult the factory.
Consult factory for material substitutions, dimensional modification possibilities, lubrication holes and grooves in balls.
Bearings are traceable. For non-traceable units, contact the factory
