Things You Have Never Heard About Industrial Gear OilOn October 5, 2023 by admin
Industrial gear oil is a specialized lubricant that plays a crucial role in ensuring the smooth operation of gears and bearings in various industrial applications. While many are familiar with its general purpose, there are some lesser-known facts about industrial gear oil that are worth exploring:
Industrial gear oils are graded based on their viscosity, which determines their flow and lubricating properties. The most common grading system used is the ISO viscosity grade. For instance, ISO VG 320 represents industrial gear oil with a viscosity of 320 centistokes at 40°C.
Extreme pressure (EP) additives:
To withstand high loads and pressures, industrial gear oils often contain extreme pressure additives. These additives create a protective film on gear surfaces, preventing metal-to-metal contact even under extreme conditions.
Synthetic gear oils:
While mineral-based gear oils are widely used, synthetic gear oils are gaining popularity due to their superior performance characteristics. Synthetic oils offer better oxidation resistance, wider temperature stability, and extended drain intervals.
Some industries, like agriculture and forestry, require environmentally friendly lubricants. There are biodegradable industrial gear oils formulated with biodegradable base oils and additives, making them eco-friendly alternatives.
Food- grade gear oils:
In the food processing and pharmaceutical industries, food-grade gear oils are used to ensure the safety and compliance of lubricants with strict regulations. These oils are designed to meet the highest hygiene standards and are NSF H1 certified.
Gear oil additives:
Besides EP additives, gear oils may contain other additives such as anti-wear agents, corrosion inhibitors, and foam suppressants. These additives enhance the performance and protection of the gear oil. Additionally, to ensure the health of industrial gear systems, regular oil analysis is performed. This involves testing the oil for wear particles, contaminants, and chemical properties to detect any signs of impending issues.
Change in color over time:
Industrial gear oils can change in color as they age and become contaminated. This color change can be used as an indicator of the oil’s condition, helping maintenance professionals assess when it’s time for an oil change. In short, industrial gear oil is a multifaceted lubricant with various formulations and applications. Understanding its characteristics, grades, and additives is vital for ensuring the efficient and reliable operation of industrial machinery while adhering to industry-specific regulations and environmental standards.
