👉 The bed fluid, also known as subbed fluid or lubricant, is a specialized lubricant used in hydraulic systems to reduce friction and wear between moving parts within the system, such as pistons and cylinders. It is typically a viscous fluid that flows freely when pressure is applied, ensuring smooth operation and minimizing energy loss due to friction. The bed fluid also helps dissipate heat generated during operation, maintaining optimal system temperatures and prolonging the lifespan of components. This fluid is crucial for the efficient and reliable functioning of hydraulic machinery, including those found in heavy machinery, construction equipment, and industrial applications.
