NA120CP0 Bearing Product Overview & Core Advantages
The NA120CP0 is a thin-section ball bearing featuring a single-row design and Endura-Kote chromium plating. Engineered for applications requiring compact cross-sections and high precision within ABEC-1 tolerance class, it excels in handling radial loads with a robust dynamic load rating of 1078 lbf and static load rating of 3720 lbf. Its plated surface enhances corrosion resistance, while the lubricated construction ensures reliable operation across a broad temperature range from -30°C to 110°C.

NA120CP0 Bearing Structural Features & Performance Benefits
Compact Thin-Section Design: With a minimal cross-section (0.25" width) relative to its large bore diameter, this bearing enables space-optimized designs while maintaining structural integrity.
Superior Material Construction: Manufactured from chrome steel rings and chrome steel balls with a brass cage, the bearing delivers excellent durability and smooth operation under radial loads.
Enhanced Surface Protection: The Endura-Kote chromium plating provides superior corrosion resistance, extending service life in challenging environments.
Precision Performance: The ABEC-1 tolerance class ensures consistent running accuracy, while the controlled radial internal clearance (0.0000 – 0.0005") guarantees optimal performance in precision applications.
