6307 M/C3 Bearing Product Overview & Core Advantages
The 6307 C3 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. Engineered with metric dimensions and manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers reliable operation and long service life. Its key advantage lies in its optimized radial load capacity and the specified C3 radial internal clearance, which makes it particularly suitable for applications involving thermal expansion, high speeds, or where interference fits are used. Constructed entirely from chrome steel for both rings and balls, it ensures high durability and resistance to wear.
6307 M/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 63 | Series designation indicating a medium width, robust deep groove ball bearing. |
| 07 | Bore diameter code, corresponding to a 35 mm bore. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications with thermal expansion or where shaft and housing fits create a reduction in operational clearance. |
6307 M/C3 Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and machined metal cage provide stable guidance for the balls, enabling the bearing to handle not only high radial loads but also moderate axial loads in both directions.
- High-Speed Capability: With a limiting speed of 8,500 rpm, the precision-ground components and robust cage design ensure smooth operation at high rotational velocities.
- Optimized Internal Clearance (C3): The C3 clearance is a key performance feature, preventing bearing seizure under operational thermal gradients and ensuring optimal performance in applications with tight fitting conditions.
- Open Design & Versatility: As an open bearing, it offers flexibility for the user to apply the most suitable lubrication for the specific application, maximizing performance and service life.
6307 M/C3 Bearing Typical Application Areas
The 6307 C3 bearing is a versatile component found in a wide range of industrial machinery, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (conveyors, pulleys)
