6309/HC5C3 Bearing Product Overview & Core Advantages
The 6309/HC5C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. Constructed with a hybrid ceramic design featuring Silicon Nitride (Si3N4) balls and chrome steel rings, this bearing delivers superior high-speed capability and extended service life. Its open design allows for versatile lubrication options, while the C3 radial internal clearance ensures optimal operation under thermal expansion conditions. This bearing is designed to handle significant radial loads with high reliability.
6309/HC5C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| HC5 | Hybrid Ceramic with Silicon Nitride (Si3N4) balls | Reduced friction, higher speed capability, electrical resistance, and longer life. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications, preventing preload and potential seizure. |
6309/HC5C3 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and Silicon Nitride balls significantly reduces rotational mass and friction, enabling higher limiting speeds (6,700 rpm) and reduced operating temperatures compared to all-steel bearings.
- High Load Capacity: With a dynamic load rating of 11,915 lbf and a static load rating of 7,194 lbf, this bearing is robust enough for applications with substantial radial loads.
- Precision & Rigidity: Manufactured to ABEC 1 | ISO P0 tolerance class, it provides reliable and consistent performance. The single row deep groove geometry offers a simple yet highly effective design for stability.
- Operational Versatility: The open seal type allows for the use of various lubrication systems, while the C3 clearance makes it suitable for applications with significant temperature fluctuations.
6309/HC5C3 Bearing Typical Application Areas
This bearing is ideally suited for high-performance and precision applications, including:
- High-Speed Spindles in machine tools and CNC machining centers
- Electric Motors and generators requiring high rotational speeds
- Turbochargers and other automotive high-speed components
- Precision Medical Equipment and dental handpieces
- Aerospace Actuators and auxiliary power units (APUs)
