Load Ratings

The 6202 bearing has a static load rating of 1.85 kN and a dynamic load rating of 3.6 kN. These ratings indicate the maximum load that the bearing can support without permanent deformation or excessive wear.

Speed Limits

The 6202 bearing has a speed limit of 10,000 rpm. This limit is determined by factors such as bearing design, lubrication, and heat dissipation. Exceeding the speed limit can lead to bearing failure.

Material and Heat Treatment

6202 bearings are typically made of high-carbon chromium steel (AISI 52100). This material offers excellent wear resistance, strength, and durability. The bearings are heat-treated to achieve the desired hardness and toughness.

Effective Strategies

• Select the appropriate bearing: Consider factors such as load, speed, and environment when selecting a 6202 bearing.
• Lubricate properly: Use a high-quality grease or oil specifically designed for bearings.
• Maintain alignment: Ensure proper shaft and housing alignment to prevent premature bearing failure.
• Monitor bearing condition: Regularly check for signs of wear, vibration, or excessive heat.

Tips and Tricks

• Handle bearings carefully: Prevent damage by handling bearings with clean hands or gloves.
• Check for lubrication: Before installing a bearing, ensure it is properly lubricated or oiled.
• Use a seal: Protect the bearing from contaminants by using a suitable seal or shield.

Interesting Stories

Story 1: A technician once installed a 6202 bearing upside down. This resulted in premature bearing failure due to improper load distribution. Lesson learned: Pay attention to bearing orientation during installation.

Story 2: A company experienced frequent bearing failures in a critical application. Investigation revealed that the bearings were not being properly lubricated. Lesson learned: Lubrication is crucial for bearing longevity.

Story 3: A contractor faced challenges with bearing noise in a high-speed application. By replacing the 6202 bearings with a higher-precision grade, the noise was significantly reduced. Lesson learned: Precision bearings can improve performance and reduce noise.
