6304-RSNR Bearing Product Overview & Core Advantages
The 6304-RSNR is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features a sealed construction and a snap ring groove on its outer ring, enabling simplified axial location within a housing. Its key advantages include robust radial load capacity, consistent operation due to its sealed design, and enhanced mounting convenience. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a dependable balance of precision and value for a wide range of industrial uses.
6304-RSNR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6304 | Standard bearing series designation indicating a 20 mm bore, 52 mm OD, and 15 mm width. |
| RS | Denotes contact-type rubber seals on both sides. This provides effective protection against contaminants and retains lubricant. |
| NR | Indicates a snap ring groove on the outer ring. This feature allows for secure axial location, simplifying housing design and assembly. |
6304-RSNR Bearing Structural Features & Performance Benefits
- Sealed & Protected Design: The contact rubber seals (RS) effectively shield the bearing's interior from dust, moisture, and other contaminants, while also retaining lubricant. This contributes to a longer service life and reduced maintenance needs, making it suitable for dirty or humid environments.
- High Radial Load Capacity: The deep groove raceway and chrome steel construction enable the bearing to handle significant radial dynamic loads (up to 3574 lbf) and radial static loads (up to 1765 lbf), ensuring reliable performance under stress.
- Simplified Mounting & Axial Location: The integrated snap ring groove (NR) eliminates the need for complex housing shoulders or locknuts. This feature provides a secure and cost-effective method for axial positioning, reducing assembly time and complexity.
- Standard Precision & Clearance: Built to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, this bearing offers consistent running accuracy suitable for a vast majority of general industrial applications.
6304-RSNR Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
- Various General Machinery requiring reliable, sealed bearing units
