Shielded Spherical Roller Bearings

**NTN Spherical Roller Bearings & Shielded Spherical Roller Bearings: Engineered for Durability and Precision**

NTN is a global leader in bearing technology, delivering high-performance solutions designed to meet the rigorous demands of industrial machinery, automotive systems, and precision equipment. Among its extensive product range, **NTN Spherical Roller Bearings** and **Shielded Spherical Roller Bearings** stand out for their exceptional load capacity, self-aligning capability, and robust construction—making them ideal for applications where misalignment, heavy loads, and harsh operating conditions are common challenges.

### **Technical Features & Design Excellence**
NTN’s Spherical Roller Bearings are engineered with a **double-row barrel-shaped roller design**, paired with a **spherical outer ring raceway**, enabling automatic alignment to compensate for shaft deflection and housing misalignment. This unique construction reduces stress concentrations, prolonging bearing life even in demanding environments.

The **Shielded Spherical Roller Bearings** incorporate protective shields on one or both sides, providing enhanced **contamination resistance** while retaining lubrication. Unlike sealed bearings, shielded variants allow for easier relubrication, making them suitable for applications where frequent maintenance is feasible. Key technical highlights include:

– **High Load Capacity**: Optimized roller geometry and premium-grade materials ensure superior radial and axial load handling.
– **Self-Aligning Capability (±1.5° to ±3°)**: Compensates for mounting errors and shaft misalignment, reducing wear.
– **Advanced Cage Designs**: Robust steel or polymer cages minimize friction and improve high-speed performance.
– **Heat-Treated Steel Components**: Enhanced hardness and fatigue resistance for extended service life.
– **Shielded Protection**: Prevents ingress of contaminants while maintaining lubricant integrity.

### **Performance Advantages**
NTN’s Spherical Roller Bearings excel in **harsh, high-load environments** where reliability is critical. Their ability to **self-align** reduces maintenance downtime, while the shielded variants offer an optimal balance between contamination protection and lubrication efficiency. These bearings also exhibit:

– **Reduced Friction & Energy Loss**: Precision-ground surfaces and optimized roller profiles minimize power consumption.
– **Extended Lubrication Intervals**: High-quality grease or oil retention extends operational life.
– **Vibration Damping**: Stable operation in heavy machinery, reducing noise and vibration.

### **Typical Applications**
Due to their durability and adaptability, NTN Spherical Roller Bearings are widely used in:

– **Industrial Machinery**: Mining equipment, crushers, conveyors, and gearboxes.
– **Automotive Systems**: Heavy-duty truck axles, off-road vehicle transmissions, and drivetrains.
– **Precision Equipment**: Paper mill rollers, wind turbine pitch controls, and steel processing machinery.

For industries requiring **high reliability under misalignment and heavy loads**, NTN’s Spherical Roller Bearings—shielded or standard—deliver unmatched performance, ensuring smoother operation and longer service intervals. Whether in extreme industrial settings or precision automotive applications, NTN’s engineering excellence guarantees optimal efficiency and durability.
