Comprehensive Guide to 6202 Bearing Sizes: Understanding Dimensions and Applications

Introduction

6202 bearings are widely used in various industrial and automotive applications. Understanding their precise dimensions is crucial for ensuring proper fit and optimal performance. This comprehensive guide provides detailed information about the 6202 bearing size, including bore diameter, outer diameter, width, and other relevant dimensions.

Dimensions of 6202 Bearing

According to the Anti-Friction Bearing Manufacturers Association (AFBMA), these dimensions represent the standard 6202 bearing size. It is important to note that slight variations may exist among different manufacturers.

Bore Diameter

The bore diameter refers to the inner diameter of the bearing, which is designed to fit on a shaft. The standard bore diameter for a 6202 bearing is 15 mm.

Outer Diameter

The outer diameter represents the exterior diameter of the bearing, which is typically in contact with the housing or other components. For a 6202 bearing, the outer diameter is 35 mm.

Width

The width indicates the axial thickness of the bearing. In the case of a 6202 bearing, the width measures 11 mm.

Types of 6202 Bearings

6202 bearings come in various types, each designed for specific applications and load conditions. Some common types include:

• 6202-2RS: Sealed on both sides with rubber seals for protection against contaminants
• 6202-ZZ: Shielded on both sides with metal shields for light-duty applications
• 6202-OPEN: Unshielded and unsealed, suitable for applications where lubrication and cleanliness are not critical

Applications of 6202 Bearings

6202 bearings are versatile and find applications in a wide range of industries, including:

• Automotive: Transmission systems, wheel bearings, pumps
• Industrial machinery: Electric motors, fans, gearboxes
• Agricultural equipment: Tractors, harvesters, tillage implements
• HVAC systems: Compressors, blowers, fans
• Medical devices: Surgical instruments, diagnostic equipment

Importance of Correct Bearing Size

Selecting the correct bearing size is essential for ensuring proper performance and longevity. A bearing that is too small may fail prematurely due to overloading, while a bearing that is too large may not fit properly or cause excessive friction.

Benefits of Using 6202 Bearings

6202 bearings offer numerous benefits, including:

• High load capacity: Designed to handle significant loads in both radial and axial directions
• Precision manufacturing: Ensures accurate dimensions and smooth operation
• Durability: Made from high-quality materials for extended service life
• Versatility: Suitable for a wide range of applications
• Cost-effective: Readily available and affordable

Tips and Tricks

• When replacing a 6202 bearing, always use a new bearing of the same size and type.
• Ensure that the shaft and housing are properly cleaned and lubricated before installing the bearing.
• Use a bearing puller or press to install and remove the bearing without damaging it.
• Regularly inspect and lubricate the bearing to extend its lifespan.

Interesting Stories

Story 1: The Oversized Bearing

A maintenance technician once attempted to replace a 6202 bearing in a gearbox, but accidentally installed a bearing that was slightly too large. As a result, the gearbox seized up, causing significant downtime.

Lesson learned: Always confirm the correct bearing size before installation.

Story 2: The Unlubricated Bearing

A farmer neglected to lubricate the bearings in his tractor's transmission. This resulted in premature bearing failure and costly repairs.

Lesson learned: Regular lubrication is crucial for bearing longevity.

Story 3: The Dirty Bearing

A technician installed a 6202 bearing in a dusty environment without properly cleaning the shaft and housing. As a result, dirt particles got into the bearing, causing rapid wear and failure.

Lesson learned: Cleanliness is essential for optimal bearing performance.

Frequently Asked Questions (FAQs)

Q: What is the difference between a 6202 and a 6203 bearing?

A: A 6203 bearing has a bore diameter of 17 mm, while a 6202 bearing has a bore diameter of 15 mm.

Q: How often should I lubricate a 6202 bearing?

A: Lubrication frequency depends on operating conditions. As a general guideline, lubricate sealed bearings every 6 months and open bearings every 3 months.

Q: Can I use a 6202 bearing to replace a 6201 bearing?

A: No, a 6201 bearing has a smaller bore diameter than a 6202 bearing.

Q: What is the life expectancy of a 6202 bearing?

A: The life expectancy of a 6202 bearing depends on factors such as load, speed, and operating conditions. However, under normal operating conditions, a 6202 bearing can last for several years.

Q: How do I measure the bore diameter of a 6202 bearing?

A: Use a precision caliper or bore gauge to accurately measure the inner diameter of the bearing.

Q: What is the torque required to tighten a 6202 bearing?

A: The recommended torque for tightening a 6202 bearing is 10-15 Nm.
