Like any other lubricant, food-grade lubricants must provide the same inherent lubricating functions such as protection against wear, corrosion, friction, and oxidation, help to transfer power while dissipating heat, and also be compatible with various sealing materials. However, unlike other lubricants or penetrants, food-grade lubricants have to provide these functions in highly regulated food industry environments. Zoro's offering of food-grade lubricants meets the USDA’s H1, H2, and H3 food-grade designations. H1 lubricants are used in food-processing environments where incidental food contact is possible. H2 lubricants are used on machine parts and equipment where there is no possibility of contact. H3 food-grade lubricants, typically edible oils, are used to prevent rust. Whether it's a tube of synthetic grease, an aerosol can of belt dressing, or a 5-gallon pail of gear oil, we've got the range of food-grade lubricants needed to meet the most stringent requirements.
