NC180AR0 Bearing Product Overview & Core Advantages
The NC180AR0 is a single row angular contact ball bearing designed for high-performance applications requiring exceptional precision and reliability. Manufactured with inch system measurements, this bearing excels in handling combined loads, particularly significant axial loads in one direction due to its specific 30° contact angle. Its Endura-kote chromium plating provides superior corrosion resistance, while the ABEC-1 precision class ensures consistent operation in demanding environments. The compact design with a thin cross-section makes it ideal for space-constrained applications where high static load moment capacity (31,410 lbf) is critical.

NC180AR0 Bearing Structural Features & Performance Benefits
Advanced Material Construction: The bearing features chrome steel rings and balls with a brass cage, providing excellent durability and wear resistance. The Endura-kote chromium plating significantly enhances corrosion protection, extending service life in harsh environments.
High Load Capacity: With a radial dynamic load rating of 2,707 lbf and axial static load rating of 7,280 lbf, this bearing delivers exceptional performance under demanding conditions. The 30° contact angle optimizes axial load carrying capability while maintaining radial load capacity.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore and OD tolerance: -0.0016" to 0"), ensuring smooth operation and minimal vibration. The radial internal clearance of 0.0000-0.0005" provides optimal running fit for precision applications.
Temperature & Lubrication Performance: Pre-lubricated design supports operation across a wide temperature range from -30°C to 110°C, making it suitable for various industrial environments without additional maintenance requirements.
