6309-2Z/C3/GJN Bearing Product Overview & Core Advantages
The 6309-2Z/C3/GJN is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This shielded bearing excels in handling significant radial loads while offering moderate axial load capacity. Its key advantages include a generous C3 radial internal clearance for thermal expansion management in high-temperature environments, and pre-lubrication for immediate operation and long service life. Engineered with chrome steel components, it delivers high durability and reliable operation, making it an ideal choice for applications requiring dependable performance and minimal maintenance.
6309-2Z/C3/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| -2Z | Shielded on both sides | Provides effective protection against contaminants while retaining pre-applied lubrication, enhancing bearing life. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, preventing premature failure. |
| /GJN | Pre-lubricated with a polyurea-based grease | Offers excellent high-temperature stability and long-term lubrication, suitable for a wide temperature range. |
6309-2Z/C3/GJN Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-quality chrome steel construction provide high radial load capacity and reliable performance under demanding conditions.
- Optimized Internal Clearance: The C3 clearance is a critical feature that allows for smooth operation in applications prone to shaft and housing thermal expansion, reducing friction and heat generation.
- Sealed and Pre-Lubricated: The combination of 2Z shields and GJN grease creates a virtually maintenance-free solution, protecting the bearing from contamination and ensuring consistent lubrication throughout its service life.
- Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures consistent quality and reliable fit in standard industrial applications.
