6310-ZNBR/C3 Bearing Product Overview & Core Advantages
The 6310-ZNBR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. A key feature is the snap ring groove on its outer ring, which facilitates secure axial positioning and simplifies housing design. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, it is designed for applications requiring reliable operation under varying thermal conditions. The combination of shielded construction and high-quality chrome steel components ensures long service life and consistent performance.
6310-ZNBR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| Z | Shield on one side | Provides effective protection against contaminants from one side. |
| N | Snap Ring Groove | Enables secure axial location of the bearing within the housing, reducing design complexity. |
| BR | Brass Cage | Offers high strength and excellent guidance for the balls, suitable for high-speed applications. |
| C3 | Radial Internal Clearance greater than Normal | Accommodates thermal expansion, making it ideal for applications with expected temperature fluctuations or interference fits. |
6310-ZNBR/C3 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway and single row design are engineered to support significant radial dynamic load ratings (13,938 lbf) while also handling axial loads from both directions, providing versatile load-carrying capability.
Enhanced Contamination Resistance: The inclusion of a shield (Z) effectively protects the bearing's internal components from particulate contaminants, extending service life and reducing the risk of premature failure in challenging environments.
Secure Axial Location: The snap ring groove (N) on the outer ring is a critical feature that allows for positive axial positioning. This simplifies the surrounding housing design and ensures the bearing remains correctly located under operational stresses.
Stable High-Speed Operation: The brass cage (BR) provides superior ball guidance and stability, contributing to smooth operation at the specified limiting speed of 6,000 rpm. The C3 clearance further supports performance in applications where operational heat generation is a factor.
