👉 Suspension fluid, also known as lubricating oil in the context of machinery, is a critical component that serves to reduce friction and wear between moving parts within a machine. It consists of a base oil, typically mineral-based or synthetic, suspended in small particles like metal or ceramic. This suspension not only lubricates the components but also helps to dissipate heat, carry away contaminants, and provide structural support. By maintaining a thin film between moving parts, the suspension fluid minimizes direct metal-to-metal contact, thereby extending the lifespan of machinery and ensuring smooth operation.
