NTN is a globally recognized brand in the bearing industry. With a long - standing history of excellence, NTN has built a reputation for manufacturing high - quality bearings that meet the most stringent international standards. These NTN ball bearings, the SL04 - 5012NR and SL04 - 5013NR, are no exception. They are produced by a company that combines advanced technology with precision engineering, ensuring reliability and durability in every product.

2. Design and Construction

• Structure: The SL04 - 5012NR and SL04 - 5013NR ball bearings feature a well - thought - out design. They are constructed with high - grade steel, which provides excellent strength and resistance to wear. The internal structure is optimized to reduce friction, allowing for smooth and efficient operation.
• Sealing: These bearings come with a non - removable seal (NR). The seal effectively prevents contaminants such as dust, dirt, and moisture from entering the bearing, which can significantly extend the bearing's service life. This is especially important in harsh operating environments where the presence of foreign particles can cause premature wear and failure.
• Precision Manufacturing: NTN uses state - of - the - art manufacturing processes to ensure that each bearing meets strict dimensional tolerances. This precision is crucial for proper fitting and alignment within the machinery, which in turn contributes to the overall performance and stability of the equipment.

3. Performance Characteristics

• Load - Carrying Capacity: Both the SL04 - 5012NR and SL04 - 5013NR are designed to handle significant radial and axial loads. They can support heavy machinery components and operate under high - stress conditions without compromising their performance. This makes them suitable for a wide range of industrial applications, from automotive to heavy - duty manufacturing.
• Speed Capability: These ball bearings are capable of high - speed operation. Their low - friction design allows them to rotate smoothly at high revolutions per minute (RPM), reducing heat generation and minimizing energy consumption. This high - speed capability is essential for applications such as machine tools and electric motors.
• Noise and Vibration Reduction: NTN has engineered these bearings to minimize noise and vibration during operation. By reducing these unwanted factors, the bearings contribute to a quieter and more stable working environment. This is beneficial not only for the comfort of operators but also for the overall quality and performance of the machinery.

4. Application Areas

• Automotive Industry: In the automotive sector, these bearings can be used in various components such as wheel hubs, transmissions, and engines. Their high - load capacity and durability make them suitable for withstanding the demanding conditions of automotive applications, including high - speed driving and frequent starts and stops.
• Industrial Machinery: For industrial machinery, the SL04 - 5012NR and SL04 - 5013NR are ideal for use in conveyors, pumps, and compressors. Their ability to operate in harsh environments and handle heavy loads ensures reliable performance and reduces downtime due to bearing failure.
• Power Generation: In power generation plants, these bearings can be found in generators and turbines. Their high - speed capability and precision design are crucial for maintaining the efficiency and reliability of power - generating equipment.

5. Quality Assurance and After - Sales Support

• Quality Control: NTN has a comprehensive quality control system in place to ensure that each SL04 - 5012NR and SL04 - 5013NR bearing meets the highest quality standards. Every bearing undergoes rigorous testing and inspection before leaving the factory, guaranteeing its performance and reliability.
• After - Sales Support: Customers can expect excellent after - sales support when purchasing these NTN bearings. NTN has a global network of service centers and distributors that can provide technical assistance, replacement parts, and maintenance advice. This ensures that customers can get the most out of their bearings and minimize any potential downtime.

In conclusion, the NTN Ball Bearing SL04 - 5012NR and SL04 - 5013NR are high - performance bearings that offer a combination of durability, precision, and reliability.
