Double Row Cylindrical Roller Bearing

**NTN Double Row Cylindrical Roller Bearings: Engineered for Heavy Loads and Precision Performance**

NTN Corporation, a global leader in bearing technology, offers high-performance **Double Row Cylindrical Roller Bearings** designed to deliver exceptional load capacity, rigidity, and operational reliability in demanding industrial and automotive applications. These bearings are engineered to accommodate heavy radial loads while maintaining precise alignment, making them ideal for machinery and systems where durability and accuracy are critical.

### **Technical Features & Design Advantages**
NTN’s **Double Row Cylindrical Roller Bearings** feature a robust construction with two rows of precision-ground cylindrical rollers, guided by high-strength cages. Key design elements include:

– **High Radial Load Capacity**: The double-row arrangement distributes loads evenly across both rows, significantly enhancing bearing life under heavy radial forces.
– **Optimized Roller Geometry**: NTN’s advanced profiling reduces edge stress, minimizing friction and wear even under misalignment or high-speed conditions.
– **Enhanced Rigidity & Stability**: The bearings’ rigid structure prevents deflection, ensuring consistent performance in precision equipment and heavy machinery.
– **Versatile Cage Options**: Available with pressed steel or machined brass cages for improved strength and heat resistance in high-speed applications.
– **Sealing & Lubrication Options**: Customizable sealing solutions (such as contact or non-contact seals) and pre-greased configurations extend service intervals in harsh environments.

### **Performance Advantages**
NTN’s double-row cylindrical roller bearings outperform single-row designs by offering:

– **Higher Load Ratings**: Capable of handling extreme radial loads in a compact footprint, reducing the need for larger bearing assemblies.
– **Improved Running Accuracy**: Precision manufacturing ensures smooth rotation with minimal vibration, critical for machine tools and gearboxes.
– **Long Service Life**: Advanced heat treatment and surface finishing technologies enhance fatigue resistance, reducing maintenance downtime.
– **Adaptability**: Suitable for both fixed and floating bearing arrangements, accommodating thermal expansion in shaft systems.

### **Typical Applications**
These bearings are widely used in industries requiring robust, high-precision rotation, including:

– **Industrial Machinery**: Gearboxes, rolling mills, printing presses, and large pumps.
– **Automotive Systems**: Heavy-duty transmissions, axle systems, and electric vehicle drivetrains.
– **Precision Equipment**: Machine tool spindles, robotics, and wind turbine pitch/yaw systems.

By combining superior engineering with rigorous quality control, NTN’s **Double Row Cylindrical Roller Bearings** provide unmatched performance in the most challenging operating conditions. Whether in high-speed industrial equipment or heavy-load automotive applications, these bearings ensure reliability, efficiency, and extended operational life.

For applications demanding durability, precision, and load resilience, NTN’s advanced bearing solutions stand as a trusted choice for engineers worldwide.
