6307 TN9/C3 Bearing Product Overview & Core Advantages
The 6307 C3 is a single row deep groove ball bearing engineered for robust performance in demanding applications. Characterized by its open design and increased radial internal clearance (C3), this bearing is optimized to handle significant radial loads while accommodating thermal expansion in high-speed or high-temperature environments. Its construction with a nylon cage contributes to smooth operation and reduced friction, making it a reliable and efficient choice for general industrial machinery.
6307 TN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code | Interpretation | Technical Significance |
|---|---|---|
| 63 | Series Designation | Indicates a medium-duty deep groove ball bearing series. |
| 07 | Bore Diameter Code | Corresponds to a standard bore diameter of 35 mm. |
| (No Seal Suffix) | Open / Unsealed | The bearing is supplied without seals or shields, allowing for higher limiting speeds and custom lubrication solutions. |
| C3 | Radial Internal Clearance | Specifies a greater-than-normal radial internal clearance. This is critical for applications with shaft expansion or where elevated operational temperatures are expected, preventing preload and potential bearing seizure. |
6307 TN9/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and single-row design enable it to support substantial radial dynamic load ratings of 7509 lbf and static ratings of 4339 lbf, making it suitable for heavy-duty operations.
- Optimized for Speed & Temperature: The C3 clearance is a key feature that allows the bearing to perform reliably at its maximum limiting speed of 8,500 rpm and within a wide temperature range of -30°C to 120°C, accommodating thermal expansion without loss of performance.
- Lightweight & Efficient Operation: The use of a nylon cage reduces overall weight and inertial mass, promoting quieter operation and lower friction at high speeds compared to metal cages.
- Standard Precision & Versatility: Manufactured to ABEC 1 | ISO P0 tolerance class, it offers consistent quality for a wide range of industrial applications. The open design provides flexibility for the user to apply the most suitable lubrication for the specific operating conditions.
6307 TN9/C3 Bearing Typical Application Areas
The 6307 C3 bearing is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
- General machinery requiring reliable radial load support with accommodation for thermal expansion.
