212NB Bearing Product Overview & Core Advantages
The 212NB single row deep groove ball bearing is a precision radial bearing engineered for robust performance in general industrial applications. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable operation and consistent quality. Its open design facilitates easy relubrication while the snap ring groove on the outer ring provides secure axial location, simplifying housing design. This bearing is designed to handle high radial dynamic loads up to 12,612 lbf while maintaining stable operation across a wide temperature range from -30°C to 120°C.
Model Code Breakdown
| Code Segment | Technical Meaning | Performance Benefit |

| 212NB | Basic bearing designation with snap ring groove | Simplifies installation and provides secure axial positioning |
| Open | No seals or shields | Allows for custom lubrication and high-speed operation |
| CN clearance | Normal radial internal clearance | Optimal for most industrial applications with moderate temperature variations |
212NB Bearing Structural Features & Performance Benefits
Single Row Deep Groove Design: The optimized raceway geometry ensures smooth operation and efficient load distribution, making it ideal for applications requiring high radial load capacity.
Chrome Steel Construction: All components - rings, balls, and cage - are manufactured from high-quality chrome steel, providing excellent durability, wear resistance, and consistent performance under demanding conditions.
Snap Ring Groove Feature: The integrated snap ring groove on the outer ring enables positive axial location, reducing housing complexity and installation time while maintaining precise bearing positioning.
High-Speed Capability: With a limiting speed of 6,700 rpm and open construction, this bearing supports efficient high-speed operation while allowing for optimal lubrication management.
