6204-ZNR Bearing Product Overview & Core Advantages
The 6204-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 without the need for complex machining. Manufactured to P0 tolerance class with CN radial internal clearance, it delivers consistent performance for a wide range of industrial applications. Its pre-lubricated design and shielded construction contribute to low-maintenance operation and extended service life.
6204-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| Z | One-side shielded | Protects against contamination from one side while maintaining low friction. |
| NR | Snap ring groove and snap ring fitted on the outer ring | Simplifies housing design and assembly, providing secure axial location. |
6204-ZNR Bearing Structural Features & Performance Benefits
- Snap Ring Locating Feature: The outer ring is equipped with a snap ring groove and a fitted snap ring. This design eliminates the need for complex housing shoulders or end caps, reducing assembly time and cost while ensuring secure axial positioning.
- Shielded Protection: The Z-shield effectively retains the factory-applied grease lubrication and excludes larger contaminants, making the bearing suitable for applications where sealing is required but contact seals would generate excessive heat.
- Robust Construction: Made from chrome steel rings and balls with a stainless steel cage, the bearing offers high durability and corrosion resistance for the cage, contributing to stable performance under radial dynamic loads up to 3035 lbf.
- Standardized Precision: Manufactured to P0 (Normal) tolerance and standard CN radial internal clearance, this bearing provides reliable and predictable performance for general industrial use.
6204-ZNR Bearing Typical Application Areas
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (Conveyors, Pulleys)
