6306-2ZNR/C3HT51 Bearing Product Overview & Core Advantages
The 6306-2ZNR/C3 is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while its shielded design and snap ring feature provide robust protection and simplified axial location. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, this bearing offers a dependable balance of precision, durability, and performance for a wide operational temperature range.
Model Code Breakdown
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| -2Z | Non-contact shields on both sides | Provides effective protection against contaminant ingress while maintaining high limiting speed. |
| NR | Snap ring groove on the outer ring | Facilitates easy axial location within a housing, simplifying assembly and reducing the need for complex housing designs. |
| /C3 | Greater than normal radial internal clearance | Ideal for applications with anticipated thermal expansion, ensuring stable operation under varying temperature conditions. |
6306-2ZNR/C3HT51 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: The single row deep groove raceway and high-quality chrome steel construction (rings, balls, and cage) provide a high radial dynamic load rating of 6002 lbf, ensuring long service life under significant radial loads.
- Enhanced Operational Simplicity: The integrated snap ring on the outer ring eliminates the need for additional locating components, streamlining the design and installation process in housings.
- Contamination Resistance: The 2Z shields protect the bearing's interior from dust and other particulates, enhancing reliability in less-than-ideal environments without a significant penalty on the limiting speed of 9,600 rpm.
- Thermal Stability: The C3 clearance allows for differential thermal expansion between the inner and outer rings, preventing preload and potential seizure in applications where operating temperatures may vary.
6306-2ZNR/C3HT51 Bearing Typical Application Areas
This bearing is well-suited for a variety of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Material Handling Conveyors
- Agricultural Machinery
- Industrial Fans and Blowers
