Interesting Stories and Lessons Learned

Story 1:

A maintenance engineer was tasked with replacing a failed bearing in a critical piece of machinery. After consulting the manufacturer's manual, he mistakenly installed a 6203 bearing instead of a 6202. The larger bearing resulted in excessive friction, leading to overheating and premature failure. Lesson learned: Pay meticulous attention to bearing size specifications.

Story 2:

A technician was troubleshooting a noisy gearbox. Upon investigation, it was discovered that a 6202 bearing was contaminated with dirt and debris. The contamination caused uneven wear on the raceways, resulting in increased vibration and noise. Lesson learned: Keep bearings clean and protected from contaminants.

Story 3:

A designer was working on a new medical device that required a small, high-speed bearing. After evaluating several options, they settled on a 6202 bearing with a reduced outer diameter. The smaller bearing allowed for a compact design and enabled the device to operate at higher speeds. Lesson learned: Choose bearing size based on specific application requirements.

Frequently Asked Questions (FAQs)

1. What is the weight of a 6202 bearing?
   - The weight of a 6202 bearing typically ranges between 0.07 and 0.11 pounds (0.03 and 0.05 kilograms).

2. What is the maximum speed rating for a 6202 bearing?
   - The maximum speed rating for a 6202 bearing varies depending on the specific model and manufacturer. It typically ranges from 6,000 to 15,000 revolutions per minute (RPM).
