Which alignment condition is characterized by both shaft centerlines being parallel but offset from each other?
Answer: Parallel (offset) misalignment
Parallel misalignment occurs when shaft centerlines are parallel but not collinear, producing a 2X vibration frequency signature.
What is the primary goal of the 'Quality Maintenance' pillar in TPM?
Answer: Eliminate quality defects by maintaining equipment conditions that produce zero defects
Quality Maintenance establishes and maintains equipment conditions that prevent quality defects at the source, rather than detecting them downstream.
A criticality analysis ranks assets by which two primary factors?
Answer: Failure frequency and consequence severity
Criticality is typically determined by multiplying failure frequency (or probability) by consequence severity to prioritize maintenance resources.
Which type of bearing failure is associated with fluted (corrugated) damage patterns on the raceway, typically caused by electrical current passage?
Answer: Electrical erosion (EDM pitting/fluting)
Electrical discharge machining (EDM) damage from stray currents through bearings creates characteristic fluted patterns on raceways.
In the context of TPM training, what is the purpose of a 'One-Point Lesson' (OPL)?
Answer: Provide a single-page focused knowledge transfer on one specific topic
A One-Point Lesson is a brief, visual document covering a single skill or knowledge point, designed for quick on-the-floor knowledge sharing.
When establishing a lubrication program, what does 'right lubricant' specifically refer to in the 5 Rights of Lubrication?
Answer: Selecting the lubricant with the correct viscosity and additive package for the application
The 'right lubricant' means selecting the appropriate type with the correct viscosity grade and additive chemistry suited to the specific equipment and operating conditions.
A plant experiences repeated seal failures on a centrifugal pump. Which predictive maintenance technology is best suited to detect developing seal leakage before catastrophic failure?
Answer: Ultrasonic detection of turbulent flow or leakage
Ultrasonic instruments can detect the turbulent flow and acoustic signatures of developing seal leaks long before visible leakage or catastrophic failure occurs.
