**TIMKEN® Angular Contact Ball Bearings: High-Performance Solutions for Demanding Applications**
TIMKEN® Fafnir® Double Row Angular Contact Ball Bearings (5200, 5300, and 5400 Series) represent the pinnacle of precision engineering, delivering unmatched reliability and performance in high-load, high-speed applications. Designed to handle combined radial and axial loads, these bearings are optimized for industrial machinery, automotive systems, and precision equipment where rigidity, accuracy, and durability are critical.
### **Technical Features & Design Advantages**
TIMKEN’s double row angular contact ball bearings feature a robust construction with two rows of precision-ground balls, arranged at a contact angle to support axial loads in both directions while maintaining radial load capacity. Key design elements include:
– **Optimized Contact Angle:** The angular contact design ensures efficient load distribution, reducing stress concentrations and extending bearing life.
– **High-Grade Steel Construction:** Manufactured from premium alloy steels, these bearings offer superior hardness, fatigue resistance, and wear performance.
– **Precision Ground Raceways:** Ultra-smooth raceways minimize friction, heat generation, and vibration, ensuring smooth operation even at high speeds.
– **Sealed & Shielded Options:** Select models include integrated seals or shields to protect against contaminants, making them ideal for harsh environments.
– **Pre-Lubrication for Long Service Life:** Factory-applied high-performance grease reduces maintenance needs and enhances operational efficiency.
### **Performance Benefits**
TIMKEN’s double row angular contact bearings excel in applications requiring high rigidity and low deflection. Their advantages include:
– **Increased Load Capacity:** The double row design provides higher radial and thrust load support compared to single row bearings, making them ideal for heavy-duty applications.
– **Enhanced Rigidity & Precision:** Reduced axial and radial play ensures precise shaft positioning, critical for machine tools, robotics, and high-speed spindles.
– **Extended Service Life:** Advanced heat treatment and precision manufacturing minimize wear, reducing downtime and replacement costs.
– **Versatile Mounting Options:** Available in both universal and specific mounting configurations, these bearings simplify installation in diverse machinery setups.
### **Typical Applications**
TIMKEN’s 5200, 5300, and 5400 series bearings are widely used in industries where precision and durability are paramount, including:
– **Industrial Machinery:** Machine tool spindles, pumps, compressors, and gearboxes benefit from their high rigidity and load capacity.
– **Automotive Systems:** These bearings are found in wheel hubs, transmissions, and electric vehicle drivetrains, where they handle high-speed rotational forces.
– **Precision Equipment:** Robotics, medical devices, and aerospace components rely on their accuracy and low-friction operation.
Engineered to meet the most demanding performance requirements, TIMKEN’s Fafnir® Double Row Angular Contact Ball Bearings deliver unmatched reliability, efficiency, and longevity—ensuring optimal performance in even the toughest operating conditions. Whether in heavy industrial settings or high-precision applications, these bearings provide the strength and precision needed to keep machinery running smoothly.
