6216 NR Bearing Product Overview & Core Advantages
The 6216 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable operation. Its key distinguishing feature is the snap ring groove on the outer ring, which simplifies axial positioning within a housing, reducing assembly costs and design complexity. Manufactured with precision P0 tolerance and standard CN radial internal clearance, this bearing offers robust performance for a wide range of industrial applications. Its open design allows for versatile lubrication options, making it a highly adaptable and cost-effective solution for demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6216 | Basic Bearing Designation | Indicates a single row deep groove ball bearing with a 80 mm bore and 140 mm outside diameter. |

6216 NR Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Simplified Assembly: The outer ring's snap ring groove eliminates the need for complex housing shoulders or end caps, reducing manufacturing costs and assembly time while ensuring secure axial positioning.
- High Radial Load Capacity: The deep groove raceway and robust construction enable the bearing to support significant radial dynamic load ratings of 16,366 lbf and radial static load ratings of 12,364 lbf.
- Precision and Reliability: Built to P0 tolerance class with a CN radial internal clearance, this bearing provides consistent performance and smooth operation under standard operating conditions.
- Durable Material Construction: Components made from chrome steel rings and balls, combined with a stainless steel cage, offer excellent wear resistance and longevity.
- Versatile Lubrication: The open seal type allows for the use of various greases or oils, enabling optimization for specific speed and temperature requirements up to a limiting speed of 6,000 rpm.
6216 NR Bearing Typical Application Areas
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Industrial Fans and Blowers
