NG400AR0 Bearing Product Overview & Core Advantages
The NG400AR0 is a high-performance angular contact ball bearing designed for precision applications requiring superior load handling. Manufactured to ABEC-1 precision class, this single-row bearing excels in applications demanding high rigidity and accurate rotational performance. Its defining characteristic is the optimized 30° contact angle, enabling it to efficiently support combined radial and axial loads simultaneously. The Endura-kote chromium plating provides enhanced corrosion resistance, making it suitable for harsh operating environments. With a substantial dynamic load rating of 19,153 lbf and a static load rating of 77,720 lbf, it delivers exceptional durability and long service life in demanding industrial settings.
NG400AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| NG400 | Bore Diameter (40") & Series Designation | Specifies the 40-inch bore size and the bearing's internal geometry series. |
| A | Angular Contact Design | Optimized for combined loads with a 30° contact angle. |
| R0 | Standard Radial Internal Clearance | Indicates a clearance of 0.0000 – 0.0005" for standard operating conditions. |
NG400AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides high rigidity, enabling the bearing to handle significant combined radial and axial loads. The high static load moment rating of 224,400 lbf-in ensures stability under complex loading scenarios.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control on the bore diameter and outside diameter (both -0.0020" to 0" tolerance), ensuring smooth and precise operation.
- Durable Material Construction: Components made from chrome steel (rings and balls) and a brass cage offer excellent strength, wear resistance, and dimensional stability.
- Corrosion Resistance: The Endura-kote chromium plating significantly enhances corrosion protection, extending bearing life in challenging environments with a temperature range of -30°C to 110°C.
- Optimized Lubrication: The bearing comes pre-lubricated, ensuring immediate operational readiness and reducing initial maintenance requirements.
NG400AR0 Bearing Typical Application Areas
The NG400AR0 angular contact ball bearing is ideally suited for heavy-duty industrial machinery and precision equipment where high load capacity and reliability are paramount. Key applications include:
- Large-Diameter Industrial Gearboxes and power transmission systems.
- Heavy-Duty Pumps and Compressors requiring robust axial and radial support.
- Material Handling Equipment such as large conveyor pulleys and rollers.
- Construction and Mining Machinery components subject to high static and dynamic loads.
- Precision Turntables and Indexing Tables in large-scale manufacturing systems.
