**TIMKEN® Angular Contact Ball Bearings (Fafnir® Single Row 7200, 7300, 7400 Series): Precision Performance for Demanding Applications**

TIMKEN’s Fafnir® single-row angular contact ball bearings (7200, 7300, and 7400 series) are engineered to deliver exceptional precision, durability, and load-handling capabilities in high-performance industrial, automotive, and precision equipment applications. Designed with a steep contact angle between the races and balls, these bearings excel in handling combined radial and axial loads, making them ideal for applications requiring high-speed operation, rigidity, and reliability under dynamic stress.

### **Technical Features & Design Advantages**
The 7200, 7300, and 7400 series angular contact ball bearings feature a robust single-row design with a non-separable inner and outer ring structure, ensuring stable performance under heavy loads. Key design elements include:

– **Optimized Contact Angle (15°–40°):** The angular contact design enables efficient management of axial and radial loads simultaneously, with higher contact angles (e.g., 40° in the 7400 series) providing greater thrust capacity.
– **High-Grade Steel Construction:** Manufactured from premium alloy steel, these bearings undergo advanced heat treatment for superior hardness and fatigue resistance, extending service life even in harsh conditions.
– **Precision Ground Raceways:** Ultra-smooth raceways minimize friction and heat generation, enhancing efficiency and reducing wear.
– **Cage Options:** Steel or polymer cages (depending on series and size) ensure smooth operation at high speeds while maintaining ball alignment.
– **Sealed & Shielded Variants:** Available configurations include open, shielded, or sealed bearings for contamination protection in demanding environments.

### **Performance Benefits**
TIMKEN’s angular contact ball bearings are designed to outperform in critical applications:
– **High-Speed Capability:** Low friction and balanced internal geometry allow for stable operation at elevated RPMs, making them suitable for machine tool spindles and turbochargers.
– **Axial Rigidity:** The angular contact design resists deflection under thrust loads, ensuring precision in applications like robotics and CNC machinery.
– **Extended Service Life:** Advanced materials and lubrication technologies reduce wear, lowering maintenance costs and downtime.

### **Typical Applications**
These bearings are widely used in industries where precision and reliability are paramount:
– **Industrial Machinery:** Machine tool spindles, pumps, compressors, and gearboxes requiring high rigidity and rotational accuracy.
– **Automotive Systems:** Wheel hubs, transmissions, and turbochargers where combined loads and high speeds are common.
– **Aerospace & Robotics:** Actuators, rotary tables, and precision motion control systems demanding minimal friction and high positional accuracy.

For engineers and maintenance professionals seeking a proven solution for high-load, high-speed applications, TIMKEN’s Fafnir® single-row angular contact ball bearings offer unmatched performance, durability, and efficiency—backed by over a century of bearing innovation.
