Certified Reliability Leader (CRL) Practice Test

Which method significantly aids in lowering equipment infant mortality rates?

1. Regular maintenance

2. Alignment and balancing

3. Visual inspections

4. Performance reviews

The correct answer is: Alignment and balancing

Lowering equipment infant mortality rates primarily focuses on ensuring that new equipment operates reliably from the outset. One of the most effective methods to achieve this is through alignment and balancing. Proper alignment and balancing of machinery are crucial during the initial setup and throughout the equipment's operational life. Misalignment can lead to excessive stress on components, increased wear, and ultimately premature failure. Similarly, imbalances can cause vibration issues, which further accelerate the degradation of the machine components. When equipment is aligned and balanced correctly, it not only minimizes stress and wear but also enhances performance and extends service life. This proactive approach is fundamental to preventing early failures, often referred to as "infant mortality," which is particularly prevalent in new machinery. Therefore, the correct emphasis on alignment and balancing directly correlates with improved reliability and lower failure rates shortly after equipment deployment.
