Gear Oil EP 220/320

Gear Oil EP 220/320 refers to a type of industrial lubricating oil specifically designed for use in gear systems. The "EP" stands for Extreme Pressure, indicating that this oil is formulated to provide protection under high-pressure conditions typically found in gearboxes, transmissions, and other heavy machinery.

The numbers "220/320" in the designation refer to the viscosity grade of the oil. Viscosity is a measure of the oil's thickness or resistance to flow. The higher the number, the thicker the oil. In this case, "220" and "320" represent a range of viscosities. The lower end of the range (220) is less viscous than the higher end (320).

Gear oils are used to lubricate and protect the gears from wear, friction, and corrosion. They also help to dissipate heat generated during operation. The EP additives in gear oils are particularly important because they form a protective layer on gear surfaces, preventing metal-to-metal contact and reducing wear, especially under extreme pressure conditions.

It's worth noting that when selecting a gear oil for a specific application, it's important to follow the manufacturer's recommendations and specifications to ensure optimal performance and protection for the machinery. Different gear systems might require different viscosity grades and additive packages.
