NA090AR0 Bearing Product Overview & Core Advantages
The NA090AR0 is a single row angular contact ball bearing engineered for precision applications requiring high reliability and thin section design. Featuring a robust Endura-kote chromium plating, this bearing delivers superior corrosion resistance and extended service life. Its 30° contact angle is optimized to handle significant combined loads, efficiently supporting both radial and axial forces simultaneously. Manufactured to ABEC-1 precision standards, it ensures consistent performance in demanding operational environments while maintaining a compact cross-section with a width of only 0.25".

| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| NA090 | Bore diameter designation (9 inches) | Standard inch sizing for compatibility |
| A | Angular contact design | Optimized for combined load applications |
| R0 | Radial internal clearance specification | Precise internal fit for optimal performance |
NA090AR0 Bearing Structural Features & Performance Benefits
Advanced Material Construction: The NA090AR0 utilizes chrome steel rings and chrome steel balls for exceptional durability and wear resistance. The brass cage provides superior strength and stability at various operating speeds.
Precision Engineering: With ABEC-1 tolerance class and tight dimensional tolerances (bore: -0.0012"–0", OD: -0.0012"–0"), this bearing ensures precise fitment and reliable operation. The 30° contact angle enables optimal load distribution between radial and axial directions.
Surface Enhancement Technology: The Endura-kote chromium plating offers excellent corrosion protection and reduced friction, while the pre-lubrication ensures immediate operational readiness across the temperature range of -30°C to 110°C.
Load Capacity Excellence: Rated for 954 lbf dynamic radial load and 2470 lbf static axial load, this bearing demonstrates robust performance under demanding conditions. The 9360 lbf static load moment rating confirms its stability in moment-loaded applications.
