6208-ZNR Bearing Product Overview & Core Advantages
The 6208-ZNR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable operation. This shielded bearing features an integral snap ring on its outer ring, enabling simplified axial location within a housing. Manufactured with precision to P0 tolerance class, it offers robust performance for a wide range of industrial applications. Its pre-lubricated, shielded design provides effective contamination protection, making it a low-maintenance and durable solution.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6208 | Standard bearing series and size designation | Indicates a standard metric bearing with a 40mm bore and 80mm outside diameter. |
| Z | Shield on one side | Protects the bearing from contaminants like dust while retaining lubrication. |
| NR | Snap Ring (fitted) on the outer ring | Allows for secure axial positioning, simplifying housing design and assembly. |
6208-ZNR Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The single row deep groove construction is optimized to support significant radial dynamic loads (7306 lbf) and radial static loads (4271 lbf), ensuring reliable performance under demanding conditions.
- Simplified Assembly & Axial Location: The integrated snap ring eliminates the need for a separate shoulder in the housing, reducing machining costs and assembly time. This feature is critical for applications requiring precise axial positioning.
- Contamination Protection & Long Service Life: The non-contact shield effectively seals the bearing, protecting the chrome steel rings and balls from particulate contamination. Combined with pre-applied grease lubrication, this design ensures a long, maintenance-free operational life.
- Robust Construction: The stainless steel cage provides excellent strength and corrosion resistance, contributing to stable operation at the specified limiting speed of 11,000 rpm.
6208-ZNR Bearing Typical Application Areas
The 6208-ZNR is ideally suited for applications requiring robust radial support and simplified mounting. Key industries and equipment include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery where axial location via a snap ring is specified.
