TIMKEN’s **Fafnir® Maximum Capacity Ball Bearings (200W & 300W Series)** represent the pinnacle of engineering excellence in deep groove ball bearing technology. Designed for high radial and moderate thrust load capacities, these bearings deliver exceptional durability, smooth operation, and extended service life across a wide range of industrial, automotive, and precision equipment applications. With a legacy of innovation, TIMKEN combines advanced materials, precision manufacturing, and rigorous testing to ensure unmatched reliability in even the most demanding environments.

### **Technical Features & Performance Advantages**

1. **Optimized Raceway Geometry**
The 200W and 300W series feature deep-groove raceways with high-precision grinding, minimizing friction and ensuring consistent performance under radial and combined loads. The optimized internal geometry enhances load distribution, reducing stress concentrations and wear.

2. **High-Capacity Design**
Engineered for **maximum load-carrying capability**, these bearings utilize larger-diameter balls and reinforced raceways compared to standard deep groove bearings. This design increases radial capacity while maintaining smooth rotational performance.

3. **Premium Steel Construction**
Manufactured from **high-grade chromium steel**, TIMKEN’s deep groove ball bearings undergo specialized heat treatment processes to enhance hardness, fatigue resistance, and dimensional stability. Optional coatings and lubricants further improve corrosion resistance and high-temperature performance.

4. **Low Noise & Vibration**
Precision-machined components and superior surface finishes ensure **quiet operation**, making these bearings ideal for applications requiring minimal vibration, such as electric motors, medical devices, and precision machinery.

5. **Versatile Sealing & Lubrication Options**
Available with **shielded (ZZ), sealed (2RS), or open configurations**, the 200W and 300W series accommodate diverse operating conditions. Factory-preloaded grease options extend relubrication intervals, reducing maintenance downtime.
