Effective August 21st, 2023, the Naval Air Warfare Center Aircraft Division (NAWCAD) has disapproved Timken Aurora’s qualification status for SAE-AS81820 and SAE-AS81935 specifications. Timken Aurora is working diligently to get requalified.

  • Ball - 440C stainless steel per AMS 5630 - heat treated.
  • Optional Ball - 13-8 Mo stainless steel per AMS 5629 - heat treated. (Specify by adding suffix "C" ex.: AWC-3TC)
  • Race - 17-4PH stainless steel per AMS 5643 - heat treated.
  • Optional plating on race outside diameter can be added by adding suffix "P" for zinc nickel or cad plating or suffix "E" for zinc nickel plating (ex.: AWC-3TP/AWC-3TE)
  • PTFE Liner - (AT 3200) Permanently bonded to race inside diameter, qualified to SAE-AS81820 Type A.
  • Temperature Range: -65°F to + 325°F.
  • "K" designates Low Torque Bearing fit. No load rotational breakaway torque can be varied to meet specific application requirements.
  • Bearings can be ordered in an oversize outside diameter condition by adding suffix "D1" (.010") oversize or "D2" (.020") oversize (ex.: AWC-3TD1/AWC-3TD2)
  • Bearings listed are manufactured to conform to the dimensions, materials and configurations of SAE Specifications AS14103 (grooved) and AS14102 (plain), and are approved for procurement under these specifications.
