6212-2ZNR Bearing Product Overview & Core Advantages
The 6212-2ZNR is a single row deep groove ball bearing engineered for high-performance industrial applications requiring reliable radial load capacity and simplified installation. This shielded bearing features an integral snap ring on its outer ring, enabling secure axial positioning within housings without requiring complex machining for shoulders. Manufactured with chrome steel components and a stainless steel cage, it delivers excellent durability and corrosion resistance. Pre-lubricated with grease, the 6212-2ZNR offers maintenance-free operation and is suitable for moderate speed applications across a broad temperature range.
6212-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Provides effective contamination protection while maintaining low friction and high-speed capability |
| NR | Snap ring groove and snap ring on outer ring | Enables secure axial location in housing, simplifying assembly and reducing total system cost |
6212-2ZNR Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The deep groove raceway design enables efficient handling of radial loads with dynamic rating of 12,432 lbf and static rating of 8,093 lbf
- Simplified Installation: The integrated snap ring (outer diameter: 116.6 mm) eliminates the need for additional retaining components, reducing assembly time and complexity
- Controlled Internal Clearance: Standard CN radial internal clearance ensures optimal performance under normal operating conditions
- Maintenance-Free Operation: Factory-applied grease lubrication combined with non-contact shields provides long-term protection without requiring re-lubrication
- Wide Temperature Compatibility: Operating range of -30°C to 120°C accommodates most industrial environments
