Preventing Mechanical Damage with Pre-Lubrication

What types of mechanical damage can be prevented by pre-lubrication of the spindle?

a. Spalling
b. Pitting
c. Seal failure
d. Fretting

Answer:

a. Spalling

Final answer:

Pre-lubrication of the spindle prevents various types of mechanical damage including Spalling, Pitting, Seal Failure, and Fretting by reducing friction and wear.

Explanation:

Pre-lubrication of the spindle is important in the prevention of several issues related to mechanical wear and tear. To be specific, it helps to prevent Spalling, Pitting, Seal Failure, and Fretting.

Spalling and Pitting are both types of surface damage often seen in mechanical systems such as spindles. They can lead to failure of the system and usually occur due to lack of adequate lubrication. Seal Failure occurs when the seal that retains the lubricant is worn off or damaged, usually due to inadequate lubrication as well. Fretting is another kind of surface damage that occurs due to repetitive or oscillatory surface movement. Adequate pre-lubrication of the spindle can prevent these issues by reducing friction and wear.
