Stories of NTN's Impact

Story 1:

A leading automotive manufacturer was facing premature bearing failures in its transmission systems. NTN engineers conducted a thorough analysis and discovered that the bearings were overheating due to insufficient lubrication. NTN proposed a modified bearing design with optimized lubrication channels, which resulted in a 50% increase in bearing life.

What We Learn: Proper bearing lubrication is crucial for maximizing performance and service life.

Story 2:

A wind turbine operator was experiencing excessive noise and vibration in its generators. NTN identified the source of the issue as worn-out bearings in the generator's yaw drive system. NTN supplied the operator with specially designed bearings that were optimized for high-speed and high-load applications. The new bearings significantly reduced noise and vibration levels, improving the overall performance of the wind turbines.

What We Learn: Choosing the right bearings for the application is essential for optimal performance and reliability.

Story 3:

A food and beverage manufacturer was facing contamination issues in its machinery due to the ingress of water and other contaminants. NTN introduced its Fluororesin bearings, which are highly resistant to corrosion and contamination. These bearings eliminated the contamination problem, resulting in improved product quality and reduced maintenance costs.

What We Learn: Utilizing bearings that are designed for specific environmental conditions can significantly enhance performance and reliability.

Tips and Tricks

1. Choose the right bearing for the application: Consider factors such as load, speed, temperature, and environmental conditions.

2. Lubricate bearings properly: Use the recommended lubricant and quantity, and ensure proper lubrication intervals.

3. Mount bearings correctly: Follow the manufacturer's instructions and use appropriate tools and procedures.

4. Monitor bearing condition: Regularly inspect bearings for signs of wear, damage, or contamination.

5. Replace bearings timely: Avoid operating bearings beyond their rated service life, as this can lead to premature failure.

Common Mistakes to Avoid

1. Using the wrong bearing type: Each bearing type is designed for specific applications and loads. Using the wrong type can lead to premature failure.

2. Overloading bearings: Exceeding the rated load capacity of a bearing can cause damage and shorten its service life.

3. Improper lubrication: Incorrect lubricant or lubrication intervals can lead to wear and premature failure.

4. Installing bearings incorrectly: Incorrect mounting can cause misalignment and premature wear.

5. Ignoring bearing maintenance: Regular inspection and maintenance are crucial for extending bearing life and preventing costly failures.
