  • Corrosion and Oxidation Protection: Prevents degradation and extends service life of components.

Main Application Areas:

  • Aircraft wheel bearings
  • Electric motors and actuators
  • Helicopter rotor bearings
  • Screw-jacks and servo mechanisms
  • Airframe lubrication points, hinge pins, static joints, and landing gear components

Specifications & Approvals:

  • DEF STAN 91-52 (British)
  • DCSEA 395/A (French)
  • COMAC QPL-CMS-OL-301
  • NATO Code: G-395
  • Joint Service Designation: XG-293
  • Russian equivalents: CIATIM 201/203, VNII NP 207, ERA (VNII NP 286M), ST (NK-50)

Environmental & Safety Information:

  • Product presents minimal health hazards when used as recommended and with standard hygiene practices.
