Harmonic Grease® Gear Grease
Grease creates a protective barrier to prevent direct metal-to-metal contact of moving parts. This lubrication reduces friction and corrosion, allowing gears to last longer and run smoothly.
At Harmonic Drive, we provide high-quality grease to optimize the performance and life of your gears. Our proprietary formulas result from decades of engineering to develop a reliable product.
The Best Grease for Metal Gears
We have specifically formulated Harmonic Grease® lubrication for use with our wide range of gearheads, component sets and phase adjusters. Here are the four sizes you can purchase:
- 14 fl. oz cartridge
- .05 Kg, 2.0 Kg and 16 Kg container
Each of our grease varieties has unique properties, and you must choose the option that best suits your gear model, size and application. Selecting the right grease prolongs the gear's life and maintains its performance.

How to Store Grease for Gears
Storing gear grease correctly preserves its quality for optimal performance. We recommend observing these best storage practices:
- Examining the grease container for damage before storage
- Closing the container tightly after use to prevent contamination with dust or moisture
- Avoiding direct exposure to sunlight or heat sources such as furnaces and steam pipes
- Keeping them at room temperature
- Following a first-in-first-out system
- Maintaining the grease in its original packaging
- Placing cartridge tubes in an upright position
- Depressurizing the grease gun if you leave the cartridge tube attached
- Inspecting grease that has been in storage for a long time
- Teaching employees proper storage
When handling the gear grease, use clean tools to dispense the product and wipe off any drips before storage. Also, avoid warming a grease container with an open flame.
