NF042AR0 Bearing Product Overview & Core Advantages
The NF042AR0 is a single row angular contact ball bearing designed for high-performance applications requiring exceptional precision and reliability. Manufactured to ABEC-1 precision standards, this bearing excels at handling combined loads, particularly substantial axial loads in one direction due to its specific 30° contact angle. Its Endura-kote chromium plating provides superior corrosion resistance, making it suitable for demanding environments. The bearing's inch dimensions (4.25" bore, 5.75" OD) and robust construction offer a compact, high-capacity solution for critical machinery.
NF042AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| NF042 | Bearing series and size designation | Identifies the specific inch-size bearing series |
| A | Angular Contact design | Optimized for combined radial and axial loading |
| R0 | Standard radial internal clearance | Provides optimal performance for most applications (0.0000 – 0.0005") |
NF042AR0 Bearing Structural Features & Performance Benefits
High Load Capacity: The single row angular contact design with a 30° contact angle enables the NF042AR0 to support significant axial static load ratings of 8630 lbf and radial dynamic load ratings of 3805 lbf, making it ideal for applications with substantial thrust requirements.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore and OD tolerance: -0.0008" – 0"), ensuring consistent performance and smooth operation in precision machinery.
Corrosion Resistance: The Endura-kote chromium plating on all bearing components provides excellent protection against corrosion, extending service life in harsh environments where moisture or contaminants are present.
Robust Construction: Utilizing chrome steel rings and brass cage construction, this bearing offers durability and reliable operation across a wide temperature range of -30°C to 110°C.
