6202 Bearing Size: A Comprehensive Guide for Selection and Application

Introduction

6202 bearings are single-row, deep-groove ball bearings with a 62mm inner diameter, a 30mm outer diameter, and a 16mm width. These bearings are designed to handle radial loads and are commonly used in various industrial applications.

Benefits of 6202 Bearings

• High load capacity: 6202 bearings can withstand heavy radial loads, making them suitable for demanding applications.
• Low friction: The deep-groove design reduces friction, resulting in increased efficiency and longer bearing life.
• Durability: 6202 bearings are made from high-quality steel, providing excellent wear resistance and durability.
• Versatility: These bearings can be used in a wide range of applications, including pumps, motors, power tools, and conveyor systems.

Selecting the Right 6202 Bearing

When selecting a 6202 bearing, several factors must be considered:

• Load capacity: Determine the radial load that the bearing will be subjected to and select a bearing with a load capacity that exceeds this load.
• Speed: The bearing speed should be within the specified limits of the selected bearing.
• Operating temperature: The bearing should be able to withstand the operating temperature of the application.
• Lubrication: Choose a bearing that is compatible with the lubrication method used in the application.

Applications of 6202 Bearings

6202 bearings are commonly used in the following applications:

• Electric motors: They reduce friction between the rotor and stator, improving motor efficiency.
• Pumps: They support the shaft and facilitate smooth operation of the pump.
• Power tools: They enable smooth rotation of the motor shaft and reduce vibration.
• Conveyor systems: They support rollers and conveyors, ensuring smooth movement of materials.

Interesting Stories

Story 1

An engineer was designing a new pump for a critical industrial application. The pump required a high-capacity bearing that could withstand heavy radial loads. After extensive research, the engineer selected a 6202 bearing due to its exceptional load-bearing capabilities. The pump was successfully installed and operated flawlessly for over five years, exceeding the engineer's expectations.

Story 2

A technician was servicing a power tool that had been experiencing excessive vibration. Upon inspection, the technician discovered that the 6202 bearing supporting the motor shaft was damaged. The bearing was replaced with a new one, and the vibration was immediately eliminated. The power tool could now operate smoothly and efficiently.

Story 3

A company was facing production delays due to frequent breakdowns of their conveyor system. The issue was traced to the failure of 6202 bearings in the conveyor rollers. The bearings were replaced with a higher-grade bearing, and the conveyor system operated smoothly without any further interruptions.

Tips and Tricks

• Use a bearing puller to safely remove and install bearings.
• Lubricate bearings regularly according to the manufacturer's recommendations.
• Inspect bearings periodically for wear or damage.
• Store bearings in a clean and dry environment.

How-To Step-by-Step Approach

How to Replace a 6202 Bearing:

1. Remove the old bearing using a bearing puller.
2. Clean the bearing housing and shaft thoroughly.
3. Apply a thin layer of lubricant to the new bearing and the shaft.
4. Carefully place the new bearing onto the shaft and into the housing.
5. Secure the bearing in place with a retaining ring or other suitable method.

Why It Matters and How It Benefits

Using the correct 6202 bearing is essential for the following reasons:

• It ensures that the bearing can handle the applied loads and operates smoothly.
• It reduces friction and wear, extending the life of the bearing and the associated components.
• It helps minimize vibration and noise, improving the overall performance of the equipment.
