**NTN Angular Contact Ball Bearings: Precision Performance for Demanding Applications**

NTN’s **Single Row Angular Contact Ball Bearings** represent a cornerstone of high-performance bearing technology, engineered to handle combined radial and axial loads with exceptional precision and reliability. Designed with a contact angle between the raceways and balls, these bearings excel in applications where high-speed operation, rigidity, and accurate shaft positioning are critical. Whether in industrial machinery, automotive systems, or precision equipment, NTN’s angular contact ball bearings deliver unmatched durability and efficiency.

### **Technical Features & Design Advantages**
NTN’s single row angular contact ball bearings are meticulously crafted to optimize load distribution and minimize friction. Key features include:

– **Precision-Engineered Contact Angle (Typically 15°, 25°, 30°, or 40°)** – The defined angle allows the bearing to support higher axial loads in one direction while maintaining radial load capacity.
– **High-Grade Materials & Heat Treatment** – Manufactured from premium steel and subjected to advanced heat treatment processes, these bearings resist wear, fatigue, and deformation under heavy loads.
– **Optimized Internal Geometry** – NTN’s proprietary raceway and ball design reduces stress concentrations, enhancing speed capability and service life.
– **Cage Options (Steel, Brass, or Polyamide)** – Depending on the application, different cage materials are available to accommodate high speeds, extreme temperatures, or corrosive environments.
– **Precision Grinding & Super-Finishing** – Advanced manufacturing techniques ensure ultra-smooth surfaces, reducing vibration and noise for sensitive applications.

### **Performance Benefits**
NTN’s angular contact ball bearings are designed to outperform standard deep groove ball bearings in demanding scenarios:

– **Superior Axial Load Capacity** – The contact angle enables efficient handling of thrust loads, making them ideal for gearboxes, pumps, and spindle assemblies.
– **High-Speed Capability** – Low friction and optimized internal clearance allow stable operation at elevated RPMs, critical for machine tool spindles and turbochargers.
– **Enhanced Rigidity & Accuracy** – Precision-ground components ensure minimal deflection, supporting tight tolerances in CNC machines and robotics.
– **Extended Service Life** – Advanced lubrication retention and contamination resistance reduce maintenance frequency in harsh environments.

### **Typical Applications**
NTN’s single row angular contact bearings are widely used across industries:

– **Industrial Machinery:** Machine tool spindles, pumps, compressors, and high-speed gearboxes.
– **Automotive Systems:** Wheel hubs, transmissions, turbochargers, and electric vehicle motors.
– **Precision Equipment:** Robotics, medical devices, and aerospace actuators where accuracy is paramount.

For applications requiring even greater load capacity, NTN offers **matched bearing sets** (DB, DF, or DT configurations), which provide preloaded axial stiffness and improved alignment.

With decades of engineering expertise, NTN continues to set the benchmark for angular contact ball bearings—delivering reliability, efficiency, and precision for the most challenging mechanical systems. Whether in high-speed automation or heavy-duty automotive applications, NTN’s solutions ensure optimal performance and longevity.
