• The Misaligned Motor: A motor was running noisily despite regular lubrication. Upon inspection, it was found that the bearing was misaligned, causing uneven load distribution.
• The Forgotten Bearing: A factory worker realized they had forgotten to lubricate a bearing for weeks. To their surprise, the bearing was still operating, albeit with increased noise and vibration. It served as a reminder to never neglect bearing maintenance.

Step-by-Step Approach to Installing a 6202 Bearing

1. Clean the Mounting Surfaces: Remove any dirt or debris from the bearing and mounting surfaces.
2. Apply Lubricant: Apply a thin layer of grease or oil to the bearing raceways.
3. Align the Bearing: Place the bearing on the shaft and align it properly.
4. Tighten the Retaining Ring or Nut: Secure the bearing using a retaining ring or nut.
5. Test the Bearing: Rotate the bearing by hand to ensure smooth operation.
