Single Angular Contact Ball Bearings

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

NTN’s Single Row Angular Contact Ball Bearings are engineered to deliver exceptional precision, durability, and load-bearing performance in high-speed and high-precision applications. Designed to accommodate combined radial and axial loads, these bearings are ideal for industrial machinery, automotive systems, and precision equipment where reliability and efficiency are critical.

### **Technical Features & Design Advantages**
NTN’s Single Row Angular Contact Ball Bearings feature a robust design with a contact angle (typically 15°, 25°, 30°, or 40°) that optimizes load distribution between axial and radial forces. The bearings are available in open, shielded, or sealed configurations, with options for high-grade steel, ceramic hybrid materials, or special heat treatments to enhance performance in extreme conditions.

Key design elements include:
– **Precision-Ground Raceways** – Minimize friction and ensure smooth operation at high speeds.
– **Optimized Cage Designs** – Available in pressed steel, machined brass, or polymer cages to reduce weight, prevent slippage, and improve lubrication retention.
– **High-Grade Materials** – NTN uses premium bearing steel (SUJ2 equivalent) or hybrid ceramic balls for applications requiring corrosion resistance, electrical insulation, or ultra-high-speed capability.
– **Preloaded Matched Sets** – For applications requiring rigid axial positioning, NTN offers precision-matched bearing sets (DB, DF, DT, or tandem arrangements) to minimize deflection and improve system stiffness.

### **Performance Benefits**
– **High-Speed Capability** – Low friction and optimized internal geometry allow for superior rotational performance in spindle motors, turbochargers, and machine tool applications.
– **Enhanced Load Capacity** – The angular contact design efficiently handles combined loads, making these bearings ideal for gearboxes, pumps, and electric vehicle drivetrains.
– **Long Service Life** – Advanced lubrication technologies and surface treatments reduce wear, extending bearing life even in contaminated or high-temperature environments.

### **Typical Applications**
NTN’s Single Row Angular Contact Ball Bearings are widely used in:
– **Industrial Machinery** – CNC spindles, robotics, and high-speed machining centers where precision and rigidity are crucial.
– **Automotive Systems** – Wheel hubs, transmissions, and electric motor bearings in hybrid/electric vehicles (EVs).
– **Aerospace & Precision Equipment** – Aviation actuators, medical devices, and optical instruments requiring ultra-low vibration and noise.

With decades of expertise in bearing technology, NTN ensures that its angular contact ball bearings meet the highest industry standards, including ISO, ABEC, and DIN specifications. Whether for high-speed automation, electric mobility, or heavy-duty industrial use, NTN’s bearings provide unmatched performance and reliability.

For applications demanding precision, durability, and efficiency, NTN’s Single Row Angular Contact Ball Bearings are the trusted solution.
