Industrial greases are semi-solid lubricants used to reduce friction and wear in machinery operating under heavy loads, high temperatures, or harsh conditions. They consist of base oil, thickener, and additives that help protect components from corrosion and contamination. Greases are especially useful where liquid oils cannot stay in place or frequent relubrication is difficult. They provide long-lasting lubrication and help extend equipment life. Common applications include bearings, gears, motors, and industrial machinery.
