👉 Rack fluid, also known as bearing oil or lubricating grease, is a specialized lubricant used in mechanical systems, particularly in heavy-duty applications like industrial machinery and automotive engines. It serves to reduce friction, wear, and heat generation between moving parts within the rack system, ensuring smooth operation and extending the lifespan of components. Unlike conventional lubricants, rack fluid is formulated to withstand high loads and temperatures, often containing additives that enhance its protective properties. It forms a thin film between moving surfaces, preventing direct metal-to-metal contact and minimizing energy loss due to friction. This fluid is typically contained within a reservoir or directly circulated through the system, making it essential for maintaining the efficiency and reliability of rack-based mechanisms.
