6312NR/C3 Bearing Product Overview & Core Advantages
The 6312NR/C3 is a single row deep groove ball bearing engineered for high-performance industrial applications. This metric bearing features a snap ring groove on its outer ring for secure axial location and simplified housing design. Its key advantages include robust radial load capacity and C3 radial internal clearance, making it ideal for applications with thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable performance and consistent operation.

| 63 | Series Designation | Medium duty deep groove ball bearing series |
| 12 | Bore Diameter | 60 mm bore (12 × 5 = 60 mm) |
| NR | Snap Ring Groove | Outer ring has snap ring groove for axial location |
| C3 | Radial Internal Clearance | Greater than normal clearance for thermal expansion |
6312NR/C3 Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry enables excellent radial load capacity while accommodating moderate axial loads in both directions.
Snap Ring Feature: The integrated snap ring groove provides positive axial location, reducing housing complexity and installation time while enhancing system reliability.
C3 Clearance Advantage: The greater radial internal clearance accommodates thermal expansion in high-speed applications and interference fits, preventing premature bearing failure due to excessive preload.
Premium Material Construction: Manufactured from chrome steel for rings, balls, and cage, ensuring high durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 120°C.
