AeroShell Grease 64 (formerly 33MS) Extreme Pressure Grease

AeroShell Grease 64 is an extreme-pressure, aviation-grade grease in a 14 oz cartridge designed to protect bearings and mechanical joints under heavy loads and harsh conditions.

This premium grease, previously marketed as AeroShell 33MS, is formulated for demanding aerospace and industrial applications where high-load protection, resistance to water and oxidation, and dependable long-life lubrication are required. Supplied in a 14-ounce cartridge that fits standard grease guns, it simplifies maintenance routines and ensures consistent, expert-level application on aircraft components and heavy machinery.

What makes this grease suitable for heavy-duty and aviation use?

The formulation delivers extreme-pressure performance and durable film strength to reduce metal-to-metal contact in high-load environments. It resists washout and oxidation to help maintain lubrication intervals while protecting components from corrosion and wear.

• Extreme-pressure additives that help prevent surface damage under heavy loads.
• Stability against water exposure to maintain protection in wet conditions.
• Resistance to oxidation for extended service life and less frequent re-lubrication.
• Compatible with typical aerospace metals and fastened joints when used per maintenance guidance.

How is the 14 oz cartridge packaged and applied?

The grease comes in a 14-ounce cartridge sized to work with standard pneumatic and manual grease guns for controlled dispensing. This cartridge format reduces contamination risk and makes it easier for technicians to deliver exact volumes into fittings and bearings.

• 14 oz cartridge fits common grease guns for efficient application.
• Sealed packaging preserves product integrity until use.
• Steady flow and consistent texture for reliable metering into fittings.
• Reduces handling compared with tubs or open containers.

What maintenance improvements can users expect after switching to this grease?

Users commonly see longer intervals between services because the grease’s formulation sustains a protective film under stress and in adverse environments. Reduced wear and reduced corrosion translate into lower downtime and maintenance costs when applied correctly.

• Longer lubrication intervals through improved oxidation and shear stability.
• Less component wear under high load conditions.
• Lower risk of corrosion on treated surfaces.
• Easier, cleaner servicing with cartridge dispensing.

Are there compatibility or safety considerations to know before use?

As with any specialty lubricant, follow your equipment manufacturer’s recommendations and maintenance manuals for approved grease types. Avoid mixing with incompatible greases or additives and ensure fittings and bearing housings are cleaned of contaminants before applying fresh grease.

• Consult aircraft or equipment maintenance documentation for approved products.
• Do not mix with unknown greases without checking compatibility first.
• Store cartridges sealed and at moderate temperatures to preserve performance.
• Use appropriate PPE when servicing to prevent skin or eye exposure to lubricants and solvents.

Who is this for: AeroShell Grease 64 in the 14 oz cartridge is aimed at aircraft maintenance technicians, fleet mechanics, and industrial maintenance teams who require an extreme-pressure grease that performs reliably under heavy loads and in challenging environments. If you maintain landing gear, wheel bearings, high-load pivots, or other critical mechanical joints and need a cartridge format for precision application, this grease is designed to fit into professional maintenance workflows while helping extend component life and reduce service frequency.
