6209-ZNR Bearing Product Overview & Core Advantages
The 6209-ZNR is a single row deep groove ball bearing designed for reliable performance in demanding industrial applications. This shielded bearing offers excellent protection against contamination while its snap ring groove on the outer ring facilitates secure axial location within a housing, simplifying assembly. Manufactured to P0 tolerance class with standard CN radial internal clearance, it provides a robust solution for applications requiring consistent operation under radial loads and moderate speeds.

6209-ZNR Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The deep groove raceway and chrome steel construction enable efficient handling of significant radial dynamic load ratings (7891 lbf) and radial static load ratings (4856 lbf).
- Enhanced Contamination Protection: The integral steel shield on one side effectively seals the bearing, retaining lubricant and excluding particulate matter, contributing to extended service life.
- Simplified Assembly & Positioning: The outer ring snap ring groove eliminates the need for complex housing shoulders or end caps, allowing for cost-effective and secure mounting.
- High-Speed Capability: The combination of a stainless steel cage, optimized geometry, and grease lubrication supports a limiting speed of 11,000 rpm.
- Maintenance-Friendly Design: Pre-lubricated with grease and shielded, this bearing is ready for use and requires minimal maintenance over its operational life.
6209-ZNR Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Automotive Components (alternators, idlers)
