6006 NR Bearing Product Overview & Core Advantages
The 6006 NR is a single row deep groove ball bearing designed for outstanding performance in radial load applications. Its key distinguishing feature is the snap ring groove on the outer ring, which allows for simplified axial location within a housing, reducing assembly complexity and cost. Manufactured with precision P0 tolerance and a standard CN radial clearance, this bearing offers reliable operation and high rotational accuracy. The open design ensures versatility for various lubrication methods, making it an excellent choice for applications demanding robust performance and ease of installation.
6006 NR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6006 | Basic bearing designation, indicating a metric, single row deep groove ball bearing with a 30mm bore, 55mm OD, and 13mm width. |
| NR | Specifies that the outer ring has a snap ring groove and is supplied with a snap ring. This feature provides a positive axial location, eliminating the need for complex housing shoulders or locknuts. |
6006 NR Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Simplified Assembly: The integrated snap ring groove on the outer ring is a key structural feature that enables secure axial positioning. This design significantly simplifies housing design and assembly processes, reducing manufacturing costs and improving serviceability.
- High Radial Load Capacity: The deep groove raceway and optimized internal geometry are engineered to support high radial dynamic load ratings (3102 lbf), ensuring durability and long service life in demanding conditions.
- Precision and Stability: Built to P0 tolerance class with a standard CN radial internal clearance, this bearing provides consistent running accuracy and stable operation, which is critical for maintaining performance in precision machinery.
- High-Speed Capability: The lightweight stainless steel cage and precision-ground chrome steel components contribute to a high limiting speed of 17,000 rpm, making it suitable for high-velocity applications.
- Versatile Lubrication: The open seal type allows for the use of grease or oil lubrication, providing flexibility to select the optimal lubricant for specific operating conditions, including the specified temperature range of -30°C to 120°C.
