1. Introduction to NTN and the Product Line

NTN, a globally renowned brand, is well - recognized for its high - quality bearings. The NTN Deep Groove Ball Bearings SL04 - 5016NR and SL04 - 5026NR are part of their exceptional product portfolio. These bearings are designed to meet the demanding requirements of various industries, offering reliable and efficient performance.

2. Key Design Features

• Deep Groove Design: The deep groove design of these ball bearings allows for smooth and stable rotation. It can accommodate both radial and axial loads, making them suitable for a wide range of applications. The deep grooves also ensure that the balls are properly guided, reducing friction and wear during operation.
• NR Seal Configuration: The "NR" in the model numbers indicates the presence of seals. These seals are engineered to prevent the ingress of contaminants such as dust, dirt, and moisture. At the same time, they retain the lubricant inside the bearing, ensuring long - term lubrication and protection against corrosion. This feature significantly extends the service life of the bearings, especially in harsh operating environments.

3. Material and Manufacturing Quality

• High - Grade Steel: NTN uses high - quality steel in the production of these bearings. This steel has excellent mechanical properties, including high hardness and toughness. It can withstand high - stress conditions without deformation or cracking, ensuring the durability and reliability of the bearings.
• Precision Manufacturing: The manufacturing process of NTN bearings is highly precise. The components are machined to extremely tight tolerances, ensuring a perfect fit between the balls, races, and cages. This precision results in low vibration and noise levels during operation, which is crucial for applications where quietness is required.

4. Performance Metrics

• Load Capacity: The SL04 - 5016NR and SL04 - 5026NR bearings have impressive load - carrying capacities. They can handle significant radial loads, which is essential for applications such as electric motors, conveyor systems, and machine tools. The axial load capacity also allows them to be used in applications where there are thrust forces.
• Speed Rating: These bearings are designed to operate at high speeds. Their optimized internal geometry and high - quality materials enable them to achieve high rotational speeds without compromising performance. This makes them suitable for high - speed applications such as fans, pumps, and centrifuges.

5. Application Areas
