The Ultimate Guide to 6202 Bearing Specifications: Unlocking Performance and Efficiency

Introduction

6202 bearings are widely used in a diverse range of industries, from automotive and aerospace to manufacturing and construction. Understanding their specifications is crucial for proper selection, installation, and maintenance practices. This comprehensive guide delves deep into the intricacies of 6202 bearing specifications, empowering you with the knowledge to optimize performance and maximize bearing life.

Terminology and Design

6202 bearings are single-row deep groove ball bearings with open type. The 62 prefix denotes the metric series, the 0 indicates a single-row, the 2 represents the bore code, and the suffix denotes the bearing type (open type).

Deep groove ball bearings feature two rows of balls positioned in a deep groove, enabling them to accommodate radial and axial loads. The open type design allows for easy lubrication but requires additional protection from contaminants.

Specifications

Dimensions

Load Capacities

| Load Type | Static | Dynamic |
|---|---|
| Radial Load (C_r) | 5.95 kN | 4.00 kN |
| Axial Load (C_a) | 3.75 kN | 2.50 kN |

Speeds

Tolerances

6202 bearings are manufactured to ABEC 1 tolerances, ensuring consistent performance and reliability.

Installation and Maintenance

Installation

1. Clean the bearing bore and shaft to remove any dirt or debris.
2. Apply a thin layer of suitable lubricant to the bearing surfaces.
3. Carefully insert the bearing into the bore, ensuring proper alignment.
4. Secure the bearing with a retaining ring or other appropriate method.

Maintenance

1. Lubricate the bearing regularly according to the manufacturer's recommendations.
2. Inspect the bearing for any signs of wear or damage.
3. Replace the bearing if it exhibits excessive wear or noise.

Common Mistakes to Avoid

1. Overtightening the bearing: This can lead to premature bearing failure.
2. Underlubricating the bearing: Insufficient lubrication can cause excessive wear and shorten bearing life.
3. Installing the bearing in an unsuitable environment: Bearings exposed to extreme heat, moisture, or contaminants may fail prematurely.
4. Ignoring bearing clearances: Improper clearances can lead to noise, vibration, and premature bearing failure.

Pros and Cons

Pros

• High load capacity: Suitable for demanding applications.
• Long service life: With proper maintenance, 6202 bearings offer extended lifespans.
• Versatility: Compatible with a wide range of applications.
