**TIMKEN® Double Row Angular Contact Ball Bearings (3200, 3300 Series): Precision Performance for Demanding Applications**
TIMKEN® Double Row Angular Contact Ball Bearings (3200 and 3300 Series) are engineered to deliver exceptional load capacity, rigidity, and precision in high-performance industrial and automotive applications. Combining advanced steel technology with precision manufacturing, these bearings are designed to handle combined radial and axial loads in both directions while maintaining smooth operation at high speeds. Their robust construction and optimized internal geometry make them ideal for applications requiring superior accuracy, durability, and reliability.
### **Technical Features & Design Advantages**
TIMKEN’s Double Row Angular Contact Ball Bearings feature a two-row ball-and-raceway configuration, enabling them to support higher radial and axial loads compared to single-row designs. Key technical features include:
– **Optimized Contact Angle (25° or 40°):** The precision-machined raceways and carefully calculated contact angles ensure efficient load distribution, reducing stress concentrations and extending bearing life.
– **High-Grade Steel Construction:** Manufactured from premium clean steel, these bearings offer superior fatigue resistance and wear performance, even in harsh operating conditions.
– **Precision Ground Components:** Tight tolerances and advanced grinding techniques minimize vibration and noise, making them suitable for high-speed applications.
– **Sealed & Shielded Options:** Available with contact or non-contact seals/shields to protect against contamination while retaining lubrication.
– **Pre-Lubrication for Long Service Life:** Factory-applied high-performance grease ensures smooth operation and reduces maintenance requirements.
### **Performance Benefits**
TIMKEN’s 3200 and 3300 Series bearings excel in applications where reliability and precision are critical. Their double-row design provides:
– **Increased Load Capacity:** Supports higher radial and axial loads than single-row bearings, reducing the need for multiple bearing arrangements.
– **Enhanced Rigidity:** Minimizes deflection under heavy loads, improving accuracy in precision machinery.
– **High-Speed Capability:** Optimized internal geometry reduces friction and heat generation, enabling stable performance at elevated RPMs.
– **Extended Service Life:** Advanced materials and precision manufacturing reduce wear, lowering total cost of ownership.
### **Typical Applications**
These bearings are widely used in industries requiring robust, high-precision rotational systems, including:
– **Industrial Machinery:** Machine tool spindles, pumps, compressors, and gearboxes where high rigidity and load capacity are essential.
– **Automotive Systems:** Wheel hubs, transmissions, and electric vehicle motors demanding durability and efficiency.
– **Precision Equipment:** Robotics, medical devices, and aerospace components requiring smooth, low-friction motion.
