6011 NR Bearing Product Overview & Core Advantages
The 6011 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding applications. Its key distinguishing feature is the snap ring groove on the outer ring, which facilitates secure axial location within a housing, simplifying assembly and reducing total system costs. Manufactured with precision to P0 tolerance class, this open-type bearing is ideal for applications requiring high rotational accuracy and robust performance under significant radial loads.
6011 NR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6011 | Standard bore diameter (55 mm), outside diameter (90 mm), and width (18 mm) dimensions. |
| NR | Designates a snap ring groove on the outer ring. This feature allows for secure axial positioning against a housing shoulder, eliminating the need for complex bearing seats or end caps. |
6011 NR Bearing Structural Features & Performance Benefits
- Snap Ring Location: The integrated snap ring groove provides a simple and effective method for axial location, enhancing assembly efficiency and system rigidity. This is a key advantage for high-speed applications where precise component positioning is critical.
- High Load Capacity: The deep groove raceway and optimized internal geometry enable the bearing to support high radial dynamic load ratings of 6654 lbf, making it suitable for heavy-duty operations.
- Precision & Durability: Constructed from chrome steel rings and balls with a stainless steel cage, the bearing offers excellent durability, corrosion resistance, and stable performance within a temperature range of -30°C to 120°C.
- Versatile Lubrication: Supplied as an open bearing without pre-lubrication, it offers maximum flexibility for the user to select the optimal grease or oil for the specific application environment and limiting speed requirements (up to 10,000 rpm).
6011 NR Bearing Typical Application Areas
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Agricultural and Construction Machinery
- Material Handling Equipment
- Any application requiring a reliably located, high-capacity radial bearing with a simplified housing design.
