Common Mistakes to Avoid

1. Overloading: Exceeding the load ratings can lead to premature bearing failure.
2. Improper Lubrication: Insufficient or contaminated lubrication can cause wear and shorten bearing life.
3. Misalignment: Misalignment between the shaft and bearing can create excessive stress and damage.

How to Select a 6202 Bearing

1. Determine Load Requirements: Calculate the expected radial and axial loads on the bearing.
2. Check Size and Fit: Ensure that the bearing dimensions and tolerances meet the application requirements.
3. Consider Speed: The selected bearing must be rated for the operating speed.
4. Choose Lubrication: Select the appropriate lubrication type and method based on operating conditions.

Benefits of Using a 6202 Bearing

1. Low Friction: Deep-groove design reduces friction and ensures smooth operation.
2. High Load Capacity: Despite its small size, the 6202 bearing has a high load rating for its type.
3. Durability: Robust construction and high-quality materials ensure long service life.
4. Versatility: Suitable for a wide range of applications, including electric motors, pumps, fans, and conveyors.
