Classification and Standards

6202 bearings are classified according to the International Organization for Standardization (ISO), ensuring their consistent quality and performance worldwide. They meet rigorous standards, including:

• ISO 15: Rolling Bearings - Radial Bearings - Boundary Dimensions
• ISO 492: Tolerances for Rolling Bearings
• ISO 1132-1: Rolling Bearings - Tolerances - Part 1: Radial Bearings

Lubrication and Maintenance

Regular lubrication is essential to maintain the optimal performance of 6202 bearings. The most common lubricants include grease or oil, with the specific type depending on the operating conditions and bearing design. Proper maintenance practices, such as timely inspections and appropriate lubrication, significantly extend bearing life and prevent premature failures.

Common Mistakes to Avoid

To ensure optimal bearing performance and longevity, certain common mistakes should be avoided:

• Overloading: Exceeding the bearing's load capacity can cause premature failure.
• Misalignment: Improper alignment during installation can lead to uneven load distribution and accelerated wear.
• Contamination: Keeping bearings clean and free from contaminants is crucial to prevent damage and premature wear.

Advanced Features

Modern 6202 bearings incorporate advanced features to enhance their performance and durability, such as:

• Seals or shields: Prevent contaminants from entering the bearing, extending its service life.
• Special coatings: Improve corrosion resistance and reduce friction, ensuring smoother operation and longevity.
• Precision grinding: Ensures exact dimensions and smooth running surfaces, reducing vibration and noise.

Frequently Asked Questions
