6309/C2E Bearing Product Overview & Core Advantages
The 6309/C2E is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This metric bearing is characterized by its open design and C2 radial internal clearance, making it an excellent choice for scenarios requiring high-speed operation and precise radial load handling. Its robust construction from chrome steel ensures durability and reliable operation across a wide temperature range, delivering a dependable solution for industrial machinery.
6309/C2E Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| C2 | Radial Internal Clearance smaller than Normal (CN) | Provides tighter internal fit, reducing noise and vibration for smoother operation, ideal for precision applications. |
| E | Reinforced Design / Optimized Internal Geometry | Features a larger ball complement and optimized raceway geometry, significantly increasing the dynamic load rating and service life compared to a standard 6309 bearing. |
6309/C2E Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open seal type minimizes friction and heat generation, allowing the bearing to achieve its high limiting speed of 6,700 rpm. This makes it suitable for high-speed applications where sealed bearings would be a limiting factor.
- Superior Load Capacity: The reinforced "E" design incorporates more and larger balls, resulting in a high radial dynamic load rating of 11,915 lbf. This robust construction enables it to handle significant radial loads with enhanced longevity.
- Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance class with a controlled C2 clearance, this bearing offers reliable running accuracy and reduced operational vibration, contributing to overall system stability.
- Versatile Application Range: Constructed entirely from chrome steel, it operates reliably within a temperature range of -30°C to 120°C, ensuring performance in various environmental conditions.
6309/C2E Bearing Typical Application Areas
The 6309/C2E is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
