NA047AR0 Bearing Product Overview & Core Advantages
The NA047AR0 is a single row angular contact ball bearing designed for high-precision applications requiring exceptional performance under combined loads. Featuring inch dimensions (4.75" bore × 5.25" OD × 0.25" width), this bearing delivers reliable operation in compact spaces. Its 30° contact angle provides superior axial load capacity while maintaining effective radial load handling. The Endura-kote chromium plating enhances corrosion resistance, making it suitable for demanding environments. With ABEC-1 precision and optimized internal geometry, this bearing offers smooth operation and long service life in high-speed applications.

NA047AR0 Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to ABEC-1 tolerance standards, this bearing ensures consistent performance with minimal runout and vibration. The brass cage provides excellent stability at high speeds while reducing friction.
Superior Load Capacity: The 30° contact angle enables efficient handling of combined radial and axial loads. With a radial dynamic load rating of 657 lbf and axial static load capacity of 1640 lbf, it delivers reliable performance under demanding conditions.
Enhanced Durability: The Endura-kote chromium plating on all bearing surfaces provides superior corrosion resistance and extends service life in harsh environments. The chrome steel construction of rings and balls ensures high hardness and wear resistance.
Optimized Internal Clearance: The precise radial internal clearance (0.0000 – 0.0005") allows for optimal preload conditions, contributing to high rigidity and accurate positioning in precision applications.
