The oil in your heavy industrial gearbox is a critical component, as it lubricates the gears and bearings and helps to dissipate heat generated by the gearbox. The oil can become contaminated with debris, wear metals, and other contaminants, leading to reduced lubrication and increased wear and tear on the gearbox components. An Artec gearbox oil analysis involves taking a sample of the oil from the gearbox and subjecting it to a battery of tests to determine its condition. These tests include:

• Viscosity: viscosity @ 40 & 100 °C and viscosity index. The oil's viscosity is measured to ensure it is within the manufacturer's recommended range. Viscosity changes can indicate oil issues, such as contamination or degradation.
• Particle count: The number and size of particles in the oil are measured to determine the level of contamination. High particle counts can indicate excessive wear or other issues with the gearbox components.
• Elemental metals by ICP: The concentration of wear metals, such as iron, copper, and aluminum, is measured to determine the level of wear on the gearbox components. Elevated wear metal levels can indicate excessive wear or damage to the components.
• Additive levels: The levels of additives in the oil, such as detergents and anti-wear agents, are measured to ensure that they are within the manufacturer's recommended range. Low levels of additives can indicate that the oil is degraded or contaminated.
• Detailed Testing: Oxidation / Nitration by FTIR, ISO particle count, Acid number, PQ index, Water by KF (ppm)
• Analysis: Expert report analysis by our gearbox maintenance specialists.
• Support: Artec is ready to answer questions/concerns.
• Phone Consultation: You'll speak directly with an Artec Machine Systems engineer to cover results and equipment performance expectations.

Based on the oil analysis results, Artec's service team can determine whether the oil needs to be changed or whether other maintenance actions are required. Regular oil analysis can help identify potential issues with almost any heavy industrial and mill gearbox before they become more severe problems, which can help extend the gearbox's service life and minimize downtime.
