6309-Z/HC5C3 Bearing Product Overview & Core Advantages
The 6309-Z/HC5C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This precision bearing features a hybrid ceramic design with silicon nitride balls, offering superior high-speed capability and extended service life. Its shielded construction provides effective contamination protection while maintaining low friction. With a C3 radial internal clearance, it is ideally suited for applications with thermal expansion or heavy interference fits, ensuring reliable operation under varying thermal conditions.
6309-Z/HC5C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| Z | Non-contact steel shield on one side | Effective protection against contaminants while maintaining low torque and high-speed capability |
| HC5 | Hybrid ceramic with silicon nitride (Si3N4) balls | Enhanced speed performance, reduced weight, electrical insulation, and superior durability |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, preventing premature failure |
6309-Z/HC5C3 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with silicon nitride balls provides significant advantages including reduced friction, higher limiting speeds, and electrical insulation properties. This makes the bearing ideal for applications where electrical arcing is a concern.
Optimized Load Capacity: With a radial dynamic load rating of 11,915 lbf and static load rating of 7,194 lbf, this bearing delivers reliable performance under substantial radial loads. The deep groove raceway design efficiently handles both radial and limited axial loads.
High-Speed Performance: The hybrid ceramic design enables a limiting speed of 6,700 rpm, significantly higher than standard steel ball bearings. The reduced weight of ceramic balls minimizes centrifugal forces at high rotational speeds.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with precise dimensional control, ensuring consistent performance and easy installation in various applications.
