Food machinery lubricant

What is the difference between NSF H1 and 3H? What is NSF certification? NSF categorizes food grade lubricants into H1, H2, and H3, with H1 being suitable for "accidental contact" between lubricants and food or beverages. It can be used as a protective rust proof film, gasket, or sealing agent for food processing equipment, or as a lubricant for mechanical parts and equipment in areas where it may come into contact with food. Why should I use lubricants with H-1 certification? According to different exposure risks, equipment such as baking ovens, conveyors, and mixers are required to use H1

Lubricants for automobile production and manufacturing

The four major processes of body manufacturing in the manufacturing of complete vehicles/MRO automobiles are stamping, welding, painting, and final assembly. Among them, the chains and bearings in the painting and final assembly lines work in humid or water vapor, water spray, corrosive, and high-temperature environments, and require shrinkage testing during drying. The selection of lubricants is the most important. The braking system is compatible with elastomers such as EPDM rubber, SBR rubber, and chloroprene rubber. Non corrosive plastic, wide temperature range, good corrosion resistance, low low-temperature torque resistance to brake fluid, rust and corrosion resistance, good wetting performance, and resistance to micro motion corrosion.

Customized oil seal

Before selecting an oil seal, we need to have a preliminary understanding of its function. As the name suggests, oil seals prevent oil from flowing out and effectively store it in a space. In fact, we can understand the function of oil seals literally. Oil seals prevent lubricating oil from leaking out of power equipment, allowing the oil to be continuously and efficiently utilized.
