The Ultimate Guide to 6202 Bearing Size: Dimensions, Tolerance, and Applications

The 6202 bearing size is a widely used metric bearing dimension in many industries, particularly in automotive, agricultural, and industrial machinery applications. Understanding the dimensions and tolerances of 6202 bearings is crucial for proper selection and installation.

Dimensions and Tolerance of 6202 Bearing Size

A 6202 bearing has the following dimensions:

The bore diameter (d) is the inner diameter of the bearing, where the shaft fits. The outer diameter (D) is the external diameter of the bearing, which fits into the housing. The width (B) is the thickness of the bearing.

The tolerance values (h5 and K5) indicate the allowable variation in dimensions. These values are defined by the International Organization for Standardization (ISO) and ensure interchangeability between bearings from different manufacturers.

Applications of 6202 Bearing Size

6202 bearings are used in a wide range of applications, including:

• Automotive: Transmissions, differentials, and wheel hubs
• Agricultural: Tractors, combines, and harvesting equipment
• Industrial: Pumps, compressors, and conveyors

Transition: Due to their versatility and durability, 6202 bearings are a popular choice for various industrial applications.

Comparison of 6202 Bearing Types

There are several types of 6202 bearings available, each with its own advantages and disadvantages. Some common types include:

The choice of bearing type depends on the specific application requirements, such as load type, speed, and environmental conditions.

Transition: Understanding the different types and features of 6202 bearings helps in selecting the most suitable bearing for any application.

Case Study: Selecting the Right 6202 Bearing for a Conveyor System

A manufacturing plant was experiencing frequent bearing failures in their conveyor system. After analyzing the application, it was determined that the original 6202 deep groove ball bearings were not able to withstand the high axial loads caused by the heavy materials being conveyed.

By switching to 7202 angular contact ball bearings, the plant was able to significantly reduce bearing failures and extend the lifespan of the conveyor system. The angular contact bearings could handle the axial loads more effectively, resulting in improved reliability and reduced maintenance costs.

Stories and Lessons Learned

Story 1: The Loose Bearing

A maintenance technician was installing a 6202 bearing on a machine when he accidentally dropped it on the floor. The bearing rolled away and ended up in a remote corner of the workshop.

After hours of searching, he finally found the bearing, but to his dismay, he realized that he had lost the circlip that held the bearing in place. Without the circlip, the bearing would not be able to function properly.

Lesson Learned: Always keep track of small parts during maintenance tasks to avoid unexpected delays or equipment failures.

Story 2: The Overtightened Bearing

A new mechanic was tightening a 6202 bearing on a pump when he applied excessive force. The bearing suddenly seized up, and the pump started to make a grinding noise.

Upon inspection, it was discovered that the mechanic had overtightened the bearing, damaging the raceways and causing premature failure.

Lesson Learned: Follow recommended tightening specifications and use a torque wrench to prevent overtightening and ensure proper bearing function.

Story 3: The Misaligned Bearing

A factory worker was hurriedly installing a 6202 bearing on a conveyor belt when he failed to align the bearing properly. As a result, the bearing ran eccentrically, causing vibration and premature wear.

Lesson Learned: Proper alignment is crucial for smooth and efficient bearing operation. Always use alignment tools and follow manufacturer's guidelines to ensure correct bearing installation.

Conclusion

The 6202 bearing size is a versatile and widely used bearing dimension in various industries. Understanding the dimensions, tolerances, and applications of 6202 bearings is essential for proper selection and installation. By comparing different bearing types and considering the specific application requirements, engineers and technicians can choose the most suitable bearing for any application.
