The 6202 Bearing: A Comprehensive Guide to Its Specifications and Applications

In the realm of engineering and machinery, bearings play a crucial role in ensuring smooth operation and reducing friction. Among the vast array of bearings available, the 6202 bearing stands out as a versatile and widely used component. This article delves into the detailed specifications of the 6202 bearing, exploring its key features, dimensions, and suitability for various applications.

Understanding the 6202 Bearing

The 6202 bearing is a deep groove ball bearing with a single row of balls. It is manufactured according to international standards, designated by the "6202" code. This code denotes several important characteristics:

• 6: Indicates a deep groove ball bearing
• 2: Denotes the bearing series (light series)
• 0: Designates the inner diameter tolerance class (normal)
• 2: Represents the outer diameter tolerance class (normal)

Specifications: Dimensions and More

The 6202 bearing conforms to the following precise dimensions:

• Bore Diameter: 15 mm
• Outer Diameter: 35 mm
• Width: 11 mm
• Load Capacity: 2.22 kN dynamic, 1.07 kN static
• Speed Limit: 10,000 rpm

Material and Lubrication

The 6202 bearing is typically manufactured from bearing-grade steel, providing durability and resistance to wear. It is pre-lubricated with a high-quality grease that ensures optimal performance and extends the bearing's lifespan.

Applications: Versatility in Performance

The 6202 bearing finds applications in a wide range of industries, including:

• Automotive: In transmissions, pumps, and electric motors
• Industrial machinery: In conveyors, gearboxes, and machine tools
• Agricultural equipment: In tractors, harvesters, and irrigation systems

Effective Strategies: Maximizing Bearing Performance

To ensure optimal performance and longevity of the 6202 bearing, consider the following strategies:

• Proper Installation: Follow manufacturer instructions carefully for proper mounting and alignment.
• Adequate Lubrication: Regularly check and replenish grease levels to prevent premature wear.
• Regular Inspections: Inspect bearings periodically for signs of damage, such as vibration, noise, or excessive heat.

Potential Drawbacks: Considerations for Use

While the 6202 bearing offers numerous benefits, it may have certain drawbacks:

• Limited Load Capacity: For applications requiring higher load capacity, larger bearings should be considered.
• Speed Limitations: The bearing's speed limit may not be suitable for high-speed applications.
• Contamination Sensitivity: The bearing is sensitive to contamination, which can reduce its performance and lifespan.

Stories from the Field: Lessons Learned

Story 1:
A factory experienced excessive bearing failures in its conveyor system. Upon investigation, it was discovered that the bearings were not properly lubricated, leading to premature wear. Regular lubrication solved the issue and significantly extended the bearing lifespan.

Story 2:
A vibration issue in an electric motor was traced back to a faulty 6202 bearing. Replacing the bearing with a new one resolved the vibration and restored smooth operation.

Story 3:
A tractor operator noticed a strange noise in the gearbox. Inspection revealed that the 6202 bearing was contaminated with dirt, causing excessive friction and noise. Cleaning and relubricating the bearing eliminated the noise and prevented further damage.

Conclusion: The 6202 Bearing's Value

The 6202 bearing offers a combination of versatility, durability, and cost-effectiveness. Understanding its specifications and applying effective strategies ensures optimal performance and extends its lifespan. By carefully considering the potential drawbacks and adhering to proper maintenance practices, the 6202 bearing remains a valuable component for a wide range of applications in various industries.
