ISO 460 is a viscosity grade classification established by the International Organization for Standardization (ISO) for industrial lubricants. Viscosity is a measure of a fluid's resistance to flow, and it is a crucial property in determining the lubricating ability of oils. ISO viscosity grades help categorize lubricants based on their kinematic viscosity at 40°C (104°F) and are represented by a number followed by the letter "ISO."
In the case of ISO 460, the number "460" indicates the kinematic viscosity of the oil at 40°C in centistokes (cSt). ISO 460 oils have a relatively high viscosity, which means they are thicker and more resistant to flow compared to lower viscosity oils.
ISO 460 oils are commonly used in heavy-duty industrial applications, such as large machinery, gearboxes, circulating systems, and hydraulic systems. These applications often require oils with higher viscosity to provide sufficient lubrication and protection under heavy loads, high temperatures, and extreme operating conditions.
It's important to note that selecting the right viscosity grade of oil is crucial to ensure optimal performance and longevity of the equipment. The manufacturer's recommendations and the equipment's operating conditions should be taken into consideration when choosing the appropriate ISO viscosity grade for lubrication.
