6209-ZNBR/C3 Bearing Product Overview & Core Advantages
The 6209-ZNBR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing excels at handling primarily radial loads and offers a high limiting speed of 7,700 rpm. Its key features include shielded protection on one side to retain lubrication and exclude contaminants, and a snap ring groove on the outer ring for simplified axial location and secure mounting within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and cost-effective precision for a wide range of machinery.
6209-ZNBR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6209 | Standard bearing series designation; indicates a deep groove ball bearing with a 45mm bore, 85mm OD, and 19mm width. | Defines the core bearing dimensions and type. |
| Z | A shield (metal seal) is fitted on one side of the bearing. | Protects against large contaminants while offering low friction. |
| N | Snap ring groove on the outer ring. | Facilitates secure axial positioning, simplifying housing design and assembly. |
| BR | The bearing is supplied with a brass cage. | Provides high strength and excellent guidance for the balls, suitable for high-speed applications. |
| /C3 | Indicates a greater than normal radial internal clearance. | Accommodates thermal expansion in applications with high operating temperatures or where fits cause a reduction in internal clearance. |
6209-ZNBR/C3 Bearing Structural Features & Performance Benefits
Optimized for Radial Load Capacity: The deep groove raceway and single row design are engineered to efficiently support high radial dynamic (7351 lbf) and static (4564 lbf) loads, ensuring long service life under demanding conditions.
High-Speed Capability: The combination of the low-friction shielded design and the robust, high-strength brass cage (BR) contributes to the bearing's high limiting speed, making it suitable for a wide range of rotational applications.
Simplified Installation and Positioning: The integral snap ring groove (N) on the outer ring allows for secure axial location within a housing, eliminating the need for complex housing shoulders and reducing assembly time and cost.
Accommodates Thermal Expansion: The C3 radial internal clearance is a critical feature for applications prone to thermal expansion, preventing premature failure due to excessive preload at operating temperatures.
6209-ZNBR/C3 Bearing Typical Application Areas
The 6209-ZNBR/C3 is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators: For supporting rotor shafts and handling high speeds.
- Industrial Gearboxes and Transmissions: Where reliable radial load support is essential.
- Material Handling Equipment: Such as conveyor pulleys and rollers.
- Agricultural Machinery: Including pumps and various driveline components.
- General Industrial Machinery: A reliable choice for fans, blowers, and other machinery requiring a robust, shielded bearing with a locating feature.
