Oilers/Plant Tenders (HHC) Civil Service Practice Exam

Which method is commonly used to check if an accessible bearing is overheating?

1. Using a temperature gauge

2. Listening for unusual noises

3. Feeling the bearing

4. Checking for vibration

The correct answer is: Feeling the bearing

The correct choice, which involves feeling the bearing, is a common and practical method for checking if an accessible bearing is overheating. By carefully placing a hand near the bearing or directly touching it, a trained individual can quickly assess if the temperature is higher than normal, indicating a potential overheating issue. This technique is especially useful in environments where other measures, such as instruments, may not be readily available or feasible to use. While temperature gauges provide precise readings, they might not always be accessible in every situation. Listening for unusual noises can help identify mechanical issues but doesn't directly measure temperature. Checking for vibration is essential for assessing the dynamic behavior of bearings, but again, it doesn't specifically indicate temperature-related problems. Therefore, feeling the bearing serves as an immediate and hands-on approach to detect overheating, making it a valuable method in maintenance and operation settings.
