Conductive grease shields bearings from arcs

With the introduction of Nyogel 758G, Nye Lubricants has taken a simple but novel approach to designing an electrically conductive bearing grease.

Electrostatic discharge from motor shafts or other nearby sources can reduce the life of shaft supporting bearings from years to a matter of months.

It is estimated that millions of dollars are lost to this type of bearing damage.

With the introduction of Nyogel 758G, Nye Lubricants has taken a simple but novel approach to designing an electrically conductive bearing grease.

Nyogel 758G incorporates a proprietary combination of standard lubricant additives that not only fortify the oil and protect it from oxidation, but also work synergistically to create an electron pathway through the grease.

This technology moves away from traditionally conductive greases that mix copper, silver or carbon into the oil.

These are paste like materials that are not ideal thickening systems; they are not lubricious and too loose to "channel" the oil and under shear, the matrix of conductive particles can break down, degrading the electron pathway.

Nyogel 758G has a volume resistivity of 300ohm-cm (to CTM-12), which is comparable to or lower than electrically conductive greases that rely exclusively on conductive thickeners and conductive additives for their conductivity.
