Friction between moving surfaces can cause them to fuse and seize if not properly managed. Lubrication grease prevents this by creating a separating film between the surfaces. Grease lubrication, a modern method, provides a thin, slippery layer that reduces friction and allows smoother movement of machine parts. It consists of three components: thickener, oil, and additives. Grease can be applied either in liquid or solid form. When solid, it acts as an adhesive, joining surfaces and promoting frictionless movement.
Rolling bearings, which carry heavy loads at high speeds, rely on a lubricant film for smooth operation. Mineral oil typically forms a delicate oil film, requiring smooth surfaces and clean conditions to prevent wear. Grease, due to its viscosity, also serves as a sealant, reducing leaks and keeping out contaminants such as dirt and corrosive substances, maintaining the effectiveness of worn seals.
Grease offers several advantages over oil lubrication. It is easier to contain, requiring simpler and more cost-effective retention systems compared to oil, which often needs complex and expensive circulating equipment. Additionally, grease can suspend solid lubricants like graphite or molybdenum disulfide, which are crucial for high-temperature and high-pressure applications. Unlike oil, grease ensures these solid lubricants remain suspended, providing consistent lubrication. It also does not require frequent monitoring of fluid levels, further reducing maintenance efforts.
Benefits of Grease:
-
Ensures the correct amount of lubrication at the right time.
-
Properly lubricates bearings and rotational parts, increasing machine efficiency.
-
Extends the lifespan of machinery, ensuring optimal performance.
-
Reduces unexpected costs, downtime, and maintenance schedules.
SKF Lubrication Grease: Incorrect lubrication is a major cause of bearing failure, accounting for 36% of cases. This is often due to degraded or improperly selected grease. Bearings have specific requirements based on their size, load, speed, and temperature. SKF, with over 100 years of experience, has developed a specialized range of high-quality lubricants to meet these needs. SKF grease are designed to prolong bearing life and ensure reliable machine performance. By selecting the right SKF greases, users can improve efficiency and reduce the risk of failure
