6205NR/C3 Bearing Product Overview & Core Advantages
The 6205NR/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling high radial loads while offering moderate axial load capacity in both directions. A key feature is its snap ring groove on the outer ring, which simplifies axial location and mounting within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards and featuring a C3 radial internal clearance, it is engineered for reliable operation in applications with thermal expansion or where interference fits are used. Its open design allows for versatile lubrication options, making it a versatile and cost-effective solution for a wide range of industrial machinery.
6205NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6205 | Standard bearing series designation indicating dimensions: 25mm bore, 52mm OD, 15mm width. | Defines the core bearing dimensions for interchangeability. |
| NR | Snap Ring groove on the outer ring. | Facilitates secure axial location, simplifies housing design, and reduces assembly time. |
| C3 | Radial internal clearance greater than Normal (CN). | Accommodates thermal expansion, prevents pre-loading from interference fits, and ensures smooth operation under high-temperature conditions. |
6205NR/C3 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: The optimized raceway geometry enables the bearing to support significant radial dynamic load ratings (3147 lbf) and accommodate axial loads from both directions, providing versatile load-handling capability.
- Snap Ring Groove (NR Feature): The integrated groove for a snap ring provides a positive axial location for the outer ring. This enhances assembly accuracy, increases operational stability, and can eliminate the need for complex and costly housing shoulders or end caps.
- C3 Internal Clearance: The greater-than-normal radial clearance is critical for applications prone to thermal expansion or where tight shaft and housing fits are used. It prevents bearing seizure and maintains optimal performance under these conditions.
- High-Quality Chrome Steel Construction: All critical components—rings, balls, and cage—are manufactured from chrome steel, ensuring high strength, durability, and consistent performance with a limiting speed of 13,000 rpm.
- Open Design & Lubrication Flexibility: The absence of integral seals or shields (Open seal type) allows for the use of various lubricants (oil or grease) tailored to specific speed, temperature, and environmental requirements.
6205NR/C3 Bearing Typical Application Areas
This bearing is ideally suited for a broad spectrum of industrial applications where reliable radial load support and simplified mounting are paramount. Key sectors include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Industrial Pumps and Fans
