NG042AR0 Bearing Product Overview & Core Advantages
The NG042AR0 is a single row angular contact ball bearing featuring inch dimensions and advanced Endura-kote chromium plating. Engineered for precision applications requiring high reliability, this bearing excels at handling combined radial and axial loads simultaneously due to its optimized 30° contact angle. Manufactured to ABEC-1 precision standards, it delivers exceptional rotational accuracy and stability. The chrome steel construction with brass cage ensures durability and consistent performance across a wide temperature range from -30°C to 110°C.
NG042AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| NG | Thin section bearing series designation |
| 042 | Bore diameter specification (4.25") |
| A | Angular contact design with 30° contact angle |
| R0 | Radial internal clearance designation (0.0000 – 0.0005") |
NG042AR0 Bearing Structural Features & Performance Benefits
Optimized Contact Design: The 30° contact angle provides superior axial load capacity while maintaining excellent radial load handling, making it ideal for applications experiencing combined loading conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore and OD tolerance: -0.0008" to 0"), ensuring smooth operation and minimal vibration in precision machinery.
Advanced Surface Treatment: Endura-kote chromium plating enhances corrosion resistance and surface hardness, extending service life in demanding environments while maintaining ROHS compliance.
Robust Construction: Chrome steel rings and balls combined with a brass cage deliver high strength and thermal stability, supporting the impressive radial dynamic load rating of 6438 lbf and axial static load capacity of 14090 lbf.
