**TIMKEN® Deep Groove Ball Bearings: Precision, Durability & Performance for Demanding Applications**

TIMKEN® Deep Groove Ball Bearings, including the renowned **Fafnir® 9100K, 200K, and 300K series**, represent the pinnacle of engineering excellence in radial load handling, high-speed operation, and long service life. Designed for industrial machinery, automotive systems, and precision equipment, these bearings deliver unmatched reliability under rigorous operating conditions. With advanced materials, precision manufacturing, and optimized internal geometries, TIMKEN’s deep groove ball bearings ensure smooth motion, reduced friction, and extended performance—even in high-temperature or contaminated environments.

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

1. **Superior Load Capacity & Efficiency**
– Engineered with deep raceway grooves for optimal radial and moderate axial load distribution.
– High-grade steel construction (including chrome alloy variants) enhances fatigue resistance and load-bearing capacity.
– Precision-ground balls and raceways minimize friction, reducing energy loss and heat generation.

2. **High-Speed Capability**
– Optimized internal clearances and cage designs (such as pressed steel or polymer retainers) ensure stability at elevated RPMs.
– Low torque characteristics make them ideal for electric motors, pumps, and automotive components.

3. **Sealed & Shielded Options for Contamination Resistance**
– Available with **rubber seals (RS/2RS) or metal shields (ZZ)** to protect against dust, moisture, and debris.
– Extended relubrication intervals reduce maintenance demands in harsh industrial environments.

4. **Precision Tolerance & Quiet Operation**
– Manufactured to **ABEC-1, ABEC-3, or higher tolerances** for applications requiring tight dimensional control (e.g., medical devices, robotics).
– Smooth surface finishes reduce vibration and noise in sensitive equipment.

### **Typical Applications**
