Lubricants add a slippery coating on machinery, tools, or parts to reduce wear and friction between metal surfaces and keep equipment running smoothly. They're typically a low- to medium-viscosity fluid that's applied to bearings and other moving parts before installation. The slippery film or coating from lubricants on metal parts helps keep the parts from rubbing directly against each other. This reduces friction between the parts to prevent wear and overheating, which helps extend the life of the equipment and keeps moving parts cool. Lubricants also provide some protection against water, contaminants, and other corrosives. In addition to a wide selection of lubricants, Zoro also offers penetrants and food-grade lubricants to keep operations running smoothly.
