6011-RSNR Bearing Product Overview & Core Advantages
The 6011-RSNR is a single row deep groove ball bearing designed for reliable performance in demanding industrial applications. This metric bearing excels in handling primarily radial loads while offering robust construction and consistent operation. Its key advantages include a snap ring groove on the outer ring for simplified axial location, integrated seals (RS) for effective contamination protection, and a standard radial internal clearance (CN) suitable for most operating conditions. Manufactured to ABEC 1 | ISO P0 tolerance class, it provides a cost-effective solution without compromising on fundamental precision and durability.
6011-RSNR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Significance |
|---|---|---|
| 6011 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 55 mm bore, 90 mm OD, and 18 mm width. |
| RS | Contact Seal on One Side | Provides effective protection against contaminants and retains lubricant. The "RS" suffix typically indicates a seal is fitted on one side. |
| NR | Snap Ring Groove | The outer ring features a snap ring groove, enabling secure and straightforward axial positioning within the housing, reducing assembly complexity and cost. |
6011-RSNR Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. With a dynamic load rating of 6362 lbf and a static load rating of 4766 lbf, it is engineered to handle significant radial loads in continuous operation.
- Simplified Assembly with Snap Ring: The integrated snap ring groove (NR) eliminates the need for complex housing shoulders or end caps, facilitating easier installation and secure axial location, which is critical for maintaining bearing alignment.
- Enhanced Contamination Protection: The RS seal effectively shields the internal components from dust, moisture, and other particulate contaminants, extending bearing service life and reliability in harsh environments.
- Balanced Performance & Speed: The standard CN clearance and precision ABEC 1 grading ensure smooth, low-vibration operation, supporting a limiting speed of 7,500 rpm for a wide range of applications.
6011-RSNR Bearing Typical Application Areas
The 6011-RSNR is ideally suited for applications requiring reliable radial support with simplified mounting. Common uses include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- General Industrial Machinery where secure axial location is needed
