6306N/C3 Bearing Product Overview & Core Advantages
The 6306N/C3 is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding industrial applications. This open-type bearing features a snap ring groove on its outer ring, facilitating secure axial location and simplified housing design. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent precision. Its key advantage lies in the specified C3 radial internal clearance, which accommodates thermal expansion in applications with elevated operating temperatures or where interference fits are used, ensuring optimal performance and extended service life.
6306N/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6306 | Standard bearing series designation, indicating a medium-duty, single row deep groove ball bearing with a 30mm bore. |
| N | Identifies the presence of a snap ring groove on the outer ring for secure axial positioning. |
| /C3 | Specifies a greater than normal radial internal clearance, ideal for applications with thermal expansion or tight fits. |
6306N/C3 Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The single row deep groove construction and chrome steel components are engineered to handle significant radial dynamic loads (6002 lbf) and radial static loads (3372 lbf).
- Simplified Assembly & Location: The snap ring groove (N) allows for easy and secure axial fixation of the bearing within the housing, reducing design complexity and assembly time.
- Operational Reliability: The C3 clearance prevents pre-loading and potential bearing seizure in applications subject to shaft or housing thermal expansion, ensuring smooth operation and enhanced durability.
- Broad Temperature Range: Constructed entirely from chrome steel, the bearing operates effectively within a temperature range of -30°C to 120°C.
- Standard Precision: Conforms to ABEC 1 | ISO P0 tolerance class, providing reliable performance for a wide range of general industrial applications.
6306N/C3 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring robust radial support and secure axial location, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Agricultural Machinery
- Material Handling Equipment (conveyors, pulleys)
- General Machinery where thermal conditions necessitate C3 clearance
