Industrial Maintenance Technician Practice Test

Question: 1 / 400

Which of the following is NOT a primary reason for lubrication?

Seal out dirt and contaminants

Reduce friction

Prevent corrosion

Increase temperature

Lubrication is primarily used to enhance the performance and longevity of mechanical systems by reducing friction between moving parts, sealing out dirt and contaminants, and preventing corrosion. These factors are essential for maintaining optimal operating conditions and ensuring the reliability of machinery.

Increasing temperature, however, is not a goal of lubrication. In fact, effective lubrication aims to minimize the heat generated by friction during operation. Excessive heat can lead to component wear, failure, and decreased efficiency, which is contrary to the fundamental purpose of lubrication. Therefore, the correct identification of increasing temperature as not being a primary reason for lubrication highlights the essential qualities that effective lubrication should provide in industrial applications.
