NF040AR0 Bearing Product Overview & Core Advantages
The NF040AR0 is a single row angular contact ball bearing designed for precision applications requiring high reliability. Featuring Endura-kote chromium plating for enhanced corrosion resistance, this bearing excels in handling combined radial and axial loads simultaneously. Its 30° contact angle provides optimal axial load capacity while maintaining excellent rotational accuracy. The bearing comes pre-lubricated for immediate operation and meets ABEC-1 precision standards, making it suitable for applications demanding consistent performance under moderate speeds and loads.

NF040AR0 Bearing Structural Features & Performance Benefits
Premium Material Construction: Manufactured from chrome steel rings and balls with brass cage, ensuring dimensional stability and long service life under demanding conditions.
Enhanced Load Capacity: The 30° contact angle enables superior axial load handling (8420 lbf static) while maintaining substantial radial load capacity (3736 lbf dynamic). The bearing effectively manages combined loading scenarios common in industrial applications.
Corrosion Protection: Endura-kote chromium plating provides excellent resistance to corrosion, extending bearing life in challenging environments where moisture or chemicals are present.
Precision Performance: ABEC-1 tolerance class ensures consistent running accuracy, while the tight radial internal clearance (0.0000 – 0.0005") contributes to smooth operation and precise positioning.
NF040AR0 Bearing Typical Application Areas
- Industrial Machinery: Precision spindles, indexing tables, and rotary assemblies
- Material Handling Equipment: Conveyor systems, turntables, and positioning mechanisms
- Agricultural Equipment: Implement guidance systems and rotary components
- Food Processing Machinery: Where corrosion resistance and reliability are critical
- General Industrial Applications: Moderate speed rotating equipment requiring combined load capacity
