About

HarmonicGrease® creates a protective barrier to prevent direct metal-to-metal contact of moving parts, ensuring gears last longer and run smoothly. These proprietary formulas are the result of decades of engineering, developed for use with Harmonic Drive’s wide range of gearheads, component sets, and phase adjusters. Each grease variety has unique properties, and selecting the right option for your gear model, size, and application is crucial for prolonging gear life and maintaining performance. Varieties include SK-1A, SK-2, SK-3, 4B No.2, and HFL-1, each with specific temperature ranges and gear size compatibility. HFL-1 is a food-grade grease, NSF H1 certified, offering increased efficiency compared to conventional food-grade greases.
