oil film thickness

Oil film thickness refers to the tiny layer of lubricating oil that separates moving surfaces, such as engine parts or gears, during operation. This microscopic layer reduces friction and wear by preventing metal-to-metal contact. Maintaining the optimal oil film thickness is crucial: too thin may lead to increased wear and heat, while too thick can cause energy loss and inefficient operation. Factors like oil type, temperature, pressure, and surface conditions influence this film. Properly designed lubrication ensures smooth, reliable movement, prolonging equipment life and enhancing performance.
