Low-noise level greases are those greases that have been purified sufficiently so that there are no, or at least very few, large particles in the grease that could enter into the load zone and cause rotating elements to bump and grind, generating noise in the bearing.
These products were originally constructed for high-precision applications where the rise and fall of the bearing elements over contaminant particles entering the load zone through the grease could damage either the bearing or the driven component.
Let's take a look at a few issues surrounding this type of product.
