207NAJ Bearing Product Overview & Core Advantages
The 207NAJ is a single row deep groove ball bearing engineered for reliable performance in general industrial applications. This open-type bearing is characterized by its high radial load capacity and versatile use. A key structural feature is the snap ring groove on its outer ring, which simplifies axial positioning within a housing, reducing design complexity and assembly time. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent quality and dependable operation, making it a cost-effective solution for a wide range of machinery.
Model Code Breakdown

|---|---|
| 207 | Standard bearing series designation, defining the basic dimensions: 35mm bore, 72mm OD, 17mm width. |
| N | Indicates a snap ring groove on the outer ring for simplified axial location. |
| A | Internal design variant, typically signifying optimized internal geometry for performance. |
| J | Specifies that the bearing is manufactured from chrome steel material. |
207NAJ Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove construction is primarily designed to support high radial dynamic and static load ratings (6182 lbf / 4946 lbf), ensuring durability under demanding conditions.
Simplified Assembly with Snap Ring Groove: The presence of the outer ring snap ring groove eliminates the need for complex housing shoulders or end caps, providing a secure axial location and reducing overall assembly costs.
Standard Precision and Clearance: Built to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing delivers reliable, low-vibration performance suitable for most industrial applications.
Robust Material Construction: All core components—rings, balls, and cage—are made from chrome steel, providing high strength, wear resistance, and a long operational lifespan.
