6309-Z/GJN Bearing Product Overview & Core Advantages
The 6309-Z is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. Engineered with shielded protection on one side, it effectively prevents the ingress of contaminants while retaining lubrication. This bearing is characterized by its high radial load capacity and robust construction, making it a reliable choice for applications requiring consistent operation under substantial loads. Its metric dimensions and standardized ABEC 1 (ISO P0) tolerance ensure easy integration and reliable performance, offering an optimal balance of durability and value for a wide range of machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6309 | Standard series designation for a medium-duty, single row deep groove ball bearing with a 45mm bore. |
| -Z | Indicates a non-contact steel shield is fitted on one side of the bearing. This provides protection against large particulate contaminants without significantly increasing friction. |
| /GJN | Specifies the radial internal clearance group. GJN corresponds to the CN group (Normal clearance) as per ISO standards, which is standard for general applications. |
6309-Z/GJN Bearing Structural Features & Performance Benefits
- Optimized Load Handling: The single row deep groove raceway geometry is engineered to support high radial loads efficiently. With a dynamic load rating of 11915 lbf and a static load rating of 7194 lbf, it delivers reliable performance in strenuous conditions.
- Shielded Protection: The Z-shield offers a primary defense against dust and debris, extending bearing life by protecting the internal components. This design maintains low operating torque.
- Precision & Consistency: Manufactured to ABEC 1 (ISO P0) tolerance class, this bearing ensures smooth and quiet operation, minimizing vibration for enhanced machine performance.
- Standard Internal Clearance: The CN clearance is ideal for most industrial applications, providing a balance between fit, thermal expansion, and operational smoothness.
- Robust Material Construction: All critical components, including rings, balls, and cage, are made from high-carbon chrome steel, ensuring high strength, durability, and resistance to wear.
