6307-2Z/C3 GJN Bearing Product Overview & Core Advantages
The 6307-2Z/C3 GJN is a single row deep groove ball bearing engineered for high performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering operational reliability. The combination of shielded construction and a C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where a more generous internal fit is required, ensuring stable operation across a wide temperature range.
6307-2Z/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6307 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 35mm bore, 80mm OD, and 21mm width. |
| 2Z | Signifies shielded on both sides. These steel shields protect the bearing interior from large particulate contaminants, helping to retain grease and extend service life. |
| C3 | Indicates a radial internal clearance greater than the Normal (CN) group. This is optimal for applications with shaft or housing interference fits, or where operational heat generation is expected. |
| GJN | Designates a specific, high-quality polyurea grease filling. This lubrication is suitable for the specified temperature range and contributes to the bearing's limiting speed and long-term performance. |
6307-2Z/C3 GJN Bearing Structural Features & Performance Benefits
- Robust Construction for High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. It supports a radial dynamic load rating of 7509 lbf and a radial static load rating of 4339 lbf, making it a reliable choice for various mechanical systems.
- Optimized for Stability and Speed: The C3 clearance provides operational stability in applications prone to thermal expansion. Combined with the GJN grease and shielded design, it achieves a high limiting speed of 8,500 rpm.
- Low-Maintenance and Long Service Life: The non-contact steel shields (2Z) effectively protect the bearing from contaminants while the pre-applied polyurea grease (GJN) ensures long-term lubrication, reducing the need for maintenance.
- Precision and Compliance: Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent and reliable performance. The bearing is also ROHS and REACH compliant, meeting modern environmental regulations.
6307-2Z/C3 GJN Bearing Typical Application Areas
