The 6202 bearing is a widely used bearing in various industries, known for its durability, versatility, and cost-effectiveness. Understanding its size, specifications, and applications is crucial for engineers, technicians, and anyone working with bearings. This comprehensive guide provides detailed information about the 6202 bearing size, covering its dimensions, load ratings, and common uses.
Dimensions and Specifications
The 6202 bearing is a metric-sized bearing with an inner diameter of 15mm, an outer diameter of 35mm, and a width of 11mm. It belongs to the 62 series of deep groove ball bearings, which are characterized by their single-row construction and deep raceways. The 6202 bearing has a radial clearance of C3, indicating a slightly looser fit than the standard C0 clearance.
Load Ratings
The 6202 bearing has a dynamic load rating of 10.7kN and a static load rating of 6kN. The dynamic load rating refers to the maximum load the bearing can withstand under continuous rotation, while the static load rating indicates the maximum load the bearing can withstand without permanent deformation. These load ratings are crucial for selecting the appropriate bearing for specific applications.
Applications
The 6202 bearing finds applications in a wide range of industries, including:
- Automotive: Used in transmissions, pumps, and other rotating components.
- Industrial machinery: Used in electric motors, gearboxes, and conveyor systems.
- Aerospace: Used in aircraft engines and landing gear systems.
- Medical equipment: Used in surgical instruments, dental drills, and medical imaging devices.
- Household appliances: Used in washing machines, refrigerators, and air conditioners.
Common Mistakes to Avoid
When using 6202 bearings, it is essential to avoid the following common mistakes:
-
Incorrect mounting: Ensure proper mounting of the bearing in the housing to prevent misalignment and premature failure.
-
Overloading: Avoid exceeding the load ratings of the bearing to prevent damage and extend its life.
-
Lack of lubrication: Regular lubrication is crucial for the smooth operation and longevity of the bearing.
-
Contamination: Protect the bearing from dust, dirt, and other contaminants that can cause wear and premature failure.
Advanced Features
Certain 6202 bearings come with advanced features that enhance their performance and reliability:
