11206 Bearing Product Overview & Core Advantages
The 11206 metric double row angular contact ball bearing represents a precision-engineered solution for applications demanding high rigidity and reliable performance under combined radial and axial loads. Its double row design provides superior stiffness and load-carrying capacity compared to single row bearings, making it ideal for compact, high-precision arrangements. Manufactured with chrome steel rings and balls, and featuring a nylon cage, this bearing is optimized for smooth operation at high speeds up to 6,700 rpm. The open design, pre-lubricated for immediate use, ensures excellent performance in a wide temperature range from -30°C to 110°C.
11206 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 11206 | Basic bearing designation indicating a double row angular contact ball bearing with a 30mm bore diameter. |
| Open (Seal Type) | No integral seals or shields, allowing for higher speed capability and custom lubrication solutions. |
| CN (Radial Internal Clearance) | Standard normal clearance group, suitable for most common operating conditions and applications. |

11206 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides significantly increased radial and axial stiffness. This design enables the bearing to support substantial combined loads (radial dynamic load rating: 3510 lbf) while maintaining precise shaft positioning.
- Optimized High-Speed Performance: The lightweight nylon cage minimizes centrifugal forces and friction, contributing to the high limiting speed of 6,700 rpm. This makes the bearing suitable for demanding high-speed applications.
- Precision Dimensions & Tolerances: Manufactured to tight dimensional tolerances (bore: -0.01mm to 0), this precision bearing ensures consistent performance, reduced vibration, and accurate running in high-precision machinery.
- Material Integrity: Components made from high-grade chrome steel offer excellent wear resistance and durability, ensuring a long operational lifespan under demanding conditions.
11206 Bearing Typical Application Areas
The 11206 bearing is engineered for robust performance in a variety of industrial settings. Key application areas include:
- Machine Tool Spindles and precision gearboxes requiring high rigidity and running accuracy.
- Industrial Pumps and Compressors where reliable operation under combined loads is critical.
