👉 The guard fluid, also known as the guard lubricant or oil, is a critical component in hydraulic systems, specifically designed to protect the moving parts from wear and damage. It forms a thin film between the moving surfaces, reducing friction and preventing metal-to-metal contact, which can lead to excessive heat and potential failure. The fluid also helps dissipate heat generated during operation and can absorb contaminants, maintaining the system's efficiency and longevity. Typically, it is a specially formulated oil with additives that enhance its protective properties under varying operating conditions.
