Humorous Stories and Lessons Learned

Story 1:
An engineer insisted on using 6202 bearings for a high-speed application despite warnings from the supplier about the bearing's limiting speed. As expected, the bearings failed prematurely, causing a catastrophic machine failure. Lesson: Always consult manufacturer specifications and follow guidelines to prevent costly mistakes.

Story 2:
A maintenance technician mistakenly lubricated 6202 bearings with a petroleum-based grease instead of the recommended synthetic grease. The bearings quickly overheated and seized up, resulting in extensive downtime. Lesson: Proper lubrication is crucial to ensure optimal bearing performance and avoid failures.

Story 3:
A design team specified 6202 bearings for an application with heavy axial loads. The bearings failed after a few months of operation due to excessive axial stresses. Lesson: Select the appropriate bearing type for the intended load conditions to ensure reliable performance.

Call to Action

Understanding the specifications, benefits, and applications of 6202 bearings is essential for engineers, designers, and users to optimize performance and reliability in their applications. By considering the factors discussed in this guide, you can make informed decisions when selecting and using 6202 bearings, ensuring optimal results and avoiding potential pitfalls.
