NC090AR0 Bearing Product Overview & Core Advantages
The NC090AR0 is a single row angular contact ball bearing engineered for precision applications requiring high load capacity and dimensional stability. Featuring Endura-kote chromium plating for enhanced corrosion resistance, this bearing is designed to handle significant combined radial and axial loads simultaneously. With its inch dimensions (9" bore, 9.75" OD) and ABEC-1 precision class, it delivers reliable performance in demanding industrial environments where space constraints and load requirements are critical factors.
NC090AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
| NC090 | Basic bearing designation with inch sizing |
| A | Angular contact design with 30° contact angle |
| R0 | Radial internal clearance specification (0.0000-0.0005") |
NC090AR0 Bearing Structural Features & Performance Benefits
High Load Capacity: The 30° contact angle and optimized raceway geometry enable superior combined load handling, with dynamic radial load rating of 1822 lbf and axial static load capacity of 4630 lbf.
Precision Construction: Manufactured to ABEC-1 tolerance standards with tight dimensional control (±0.0012" on diameters) ensures consistent performance and easy installation.
Enhanced Durability: Endura-kote chromium plating provides excellent corrosion resistance while maintaining dimensional stability across the operating temperature range of -30°C to 110°C.
Optimized Material Selection: Chrome steel rings and balls combined with brass cage construction deliver reliable operation and extended service life in demanding applications.
