Below is a list of Lubricating Grease manufacturers from River Edge, New Jersey. Lubricating grease, a combination of oil and soap, is extremely viscous. Unlike oil, however, grease is a non-liquid lubricant. It is applied to machinery under heavy pressure, specifically in points of heightened friction. Lubricating grease is preferred to other petrol-based lubricants in cases where the dripping of oil is unwanted.
