6309-Z/C5 Bearing Product Overview & Core Advantages
The 6309-Z/C5 is a single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing excels at handling high radial loads and moderate axial loads in both directions. Its shielded design (Z) offers effective contamination protection, while the C5 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring reliable operation and high rigidity.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6309 | Standard series designation for a medium-duty, single row deep groove ball bearing. |
| Z | Indicates a shielded bearing on one side, providing protection against large particulate contaminants. |
| C5 | Specifies a greater than normal radial internal clearance. This is ideal for applications involving high rotational speeds or where thermal expansion of the shaft and housing is expected. |
6309-Z/C5 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry is designed to support high radial dynamic load ratings (11,915 lbf) and significant axial loads, making it a versatile choice for combination loads.
Controlled Internal Clearance: The C5 clearance group prevents pre-loading and potential overheating in applications with thermal gradients or press-fits, contributing to stable performance and extended service life.
Shielded Protection: The shielded (Z) configuration effectively excludes larger contaminants while maintaining low friction, supporting a limiting speed of 6,700 rpm. The bearing is supplied without lubrication, allowing for custom greasing to suit specific operational needs.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with chrome steel rings, balls, and cage, this bearing ensures consistent quality and reliable operation.
6309-Z/C5 Bearing Typical Application Areas
The 6309-Z/C5 is widely used across various industries due to its robust construction and specific clearance. Key applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- Ventilation and Fan Systems
