207 NR Bearing Product Overview & Core Advantages
The 207 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in standard industrial applications. This metric bearing features a snap ring on its outer ring, enabling secure axial location within a housing without requiring a complex shoulder. Its open design allows for versatile lubrication options, while the stainless steel cage ensures durability and smooth operation. The 207 NR is engineered for high reliability and is an ideal choice for applications demanding straightforward radial load support with simplified installation.
207 NR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 207 | Standard bearing series number denoting specific bearing dimensions (35mm bore, 72mm OD, 17mm width). |
| NR | Indicates the outer ring has a snap ring groove and a fitted snap ring. This feature simplifies housing design and provides secure axial location. |
207 NR Bearing Structural Features & Performance Benefits
- Snap Ring Locating Feature: The integrated snap ring (outer ring locating feature) eliminates the need for a machined shoulder in the housing, reducing manufacturing costs and simplifying assembly while ensuring reliable axial positioning.
- Radial Load Capacity: The single row deep groove construction is optimized to support significant radial dynamic load ratings of 6182 lbf and radial static load ratings of 4946 lbf, providing robust performance.
- High-Speed Capability: With a limiting speed of 10,000 rpm and a stainless steel cage, this bearing maintains stability and low friction at high rotational velocities.
- Precision & Durability: Manufactured to P0 tolerance class with standard CN radial internal clearance, it offers consistent performance. The chrome steel rings and balls provide high wear resistance and long service life.
- Versatile Lubrication: The open seal type allows for the application of various greases or oils, making it adaptable to different operational environments within its temperature range of -30°C to 120°C.
207 NR Bearing Typical Application Areas
This bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial support with easy installation.
