Category:

Shell AeroShell Grease 64

Molybdenum disulphide-fortified synthetic aircraft grease

  • Based on AeroShell Grease 33, fortified with 5% molybdenum disulphide

  • Designed for high-load, sliding aircraft components where extreme pressure (EP) performance is required

  • Synthetic hydrocarbon/ester base oil thickened with lithium complex

  • Offers superior anti-wear, anti-corrosion, and water resistance properties

  • Wide operating temperature range from –73°C to +121°C

  • Formerly known as AeroShell Grease 33MS

  • Approved to MIL-G-21164D, COMAC QPL-CMS-OL-311, NATO Code G-353, and others

Global Product Code: 001F6601



Application:

AeroShell Grease 64 is a synthetic lithium complex grease developed for aircraft sliding components subject to high loads and extreme pressures. Derived from AeroShell Grease 33 and fortified with 5% molybdenum disulphide, it provides enhanced protection against wear and corrosion in critical airframe assemblies.

Performance Features & Benefits:

  • EP Fortification: Contains 5% molybdenum disulphide for improved extreme pressure performance.
  • Anti-Wear & Anti-Corrosion: Provides robust protection in severe operating conditions.
  • Wide Temperature Tolerance: Performs reliably from –73°C to +121°C.
  • Compatibility: Shares technology base with AeroShell Grease 33 for reduced inventory complexity.

Main Application Areas:

  • Highly loaded sliding surfaces on aircraft
  • Landing gear assemblies
  • Control surface mechanisms and joints
  • Components requiring enhanced EP protection

Specifications & Approvals:

  • MIL-G-21164D
  • COMAC QPL-CMS-OL-311
  • DEF STAN 91-57 (equivalent)
  • DCSEA 353/A (equivalent)
  • NATO Code: G-353
  • Joint Service Designation: XG-276

Environmental & Safety Information:

  • Product is considered safe when used according to recommended procedures and proper hygiene practices.
  • Use gloves when handling used grease; avoid contact with skin and wash thoroughly after use.
  • Do not discharge into drains, soil, or water. Collect and dispose of via authorised collection points.
  • Safety Data Sheet (SDS) available via inquiry
