Double Row Tapered Roller Bearing

**NTN Tapered Roller Bearings: Precision, Durability, and High-Performance Solutions for Demanding Applications**

NTN is a globally recognized leader in the design and manufacturing of high-performance rolling bearings, with its tapered roller bearings standing out for their exceptional load capacity, precision, and reliability. Among NTN’s extensive bearing portfolio, the **Metric ISO Series Tapered Roller Bearings** and **Double Row Tapered Roller Bearings** are engineered to deliver superior performance in the most demanding industrial, automotive, and precision equipment applications. These bearings are designed to handle combined radial and axial loads efficiently, making them indispensable in systems where durability, high-speed operation, and long service life are critical.

### **Technical Features and Performance Advantages**

NTN’s **Metric ISO Series Tapered Roller Bearings** adhere to international dimensional standards (ISO 355), ensuring seamless compatibility with a wide range of machinery. Their precision-ground rollers and raceways are optimized for smooth rolling motion, reducing friction and heat generation. Key features include:

– **High Load Capacity**: The tapered geometry allows for effective distribution of radial and axial loads, making these bearings ideal for heavy-duty applications.
– **Enhanced Rigidity and Alignment**: The cup-and-cone design ensures stable operation even under misalignment conditions, improving overall system reliability.
– **Superior Lubrication Retention**: Advanced sealing options and optimized internal geometries help maintain lubrication, extending bearing life in harsh environments.
– **Interchangeability**: Conforming to ISO standards, these bearings offer easy replacement and integration into existing systems.

For applications requiring even greater load support and rigidity, NTN’s **Double Row Tapered Roller Bearings** provide an exceptional solution. These bearings incorporate two rows of tapered rollers, significantly increasing radial and axial load capacity while maintaining compact dimensions. Their design minimizes deflection under heavy loads, making them ideal for high-stress applications such as gearboxes, heavy machinery, and large industrial equipment.

### **Typical Applications**

NTN’s tapered roller bearings are widely used across multiple industries, including:

– **Industrial Machinery**: Machine tools, construction equipment, mining machinery, and conveyor systems benefit from their high load capacity and resistance to shock loads.
– **Automotive Systems**: Wheel hubs, transmissions, and differentials rely on these bearings for their ability to handle dynamic forces and high rotational speeds.
– **Precision Equipment**: Gear reducers, pumps, and wind turbine systems utilize NTN’s tapered roller bearings for their precision and long-term reliability.

By combining advanced materials, precision engineering, and rigorous quality control, NTN ensures that its tapered roller bearings meet the highest performance standards. Whether in heavy industrial applications or high-speed automotive systems, NTN’s Metric ISO Series and Double Row Tapered Roller Bearings deliver unmatched durability, efficiency, and operational excellence.

For demanding environments where performance cannot be compromised, NTN’s tapered roller bearings provide the strength, precision, and reliability needed to keep machinery running smoothly—ensuring reduced downtime and lower total cost of ownership.
