6309/C5 Bearing Product Overview & Core Advantages
The 6309/C5 is a single row deep groove ball bearing designed for exceptional radial load capacity and high-speed operation. This precision bearing features an open design and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable performance in a wide range of industrial applications. Its key advantage lies in the optimized C5 radial internal clearance, which accommodates thermal expansion in demanding operational conditions, making it suitable for applications with elevated temperatures or high rotational speeds.
6309/C5 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6309 | Standard bearing series designation indicating a medium-duty, single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width. |
| /C5 | Specifies a greater than normal radial internal clearance compared to standard CN clearance. This is critical for applications involving thermal expansion, high speeds, or where misalignment may be present. |
6309/C5 Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The deep groove raceway and single row design are optimized to support significant radial loads (dynamic: 11,915 lbf / static: 7,194 lbf), providing robust performance in demanding environments.
- Optimized for High-Speed Operation: With a limiting speed of 6,700 rpm, this bearing is engineered for applications requiring sustained high rotational velocities. The chrome steel cage ensures stability and reduces friction at high speeds.
- Thermal Management with C5 Clearance: The C5 radial internal clearance is a defining feature, allowing for axial displacement and accommodating thermal expansion during operation, which prevents binding and reduces operational stress.
- Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class, this bearing ensures consistent running accuracy and low vibration, contributing to the overall efficiency and longevity of the machinery.
- Material Integrity: Constructed entirely from chrome steel (rings, balls, and cage), providing high hardness, wear resistance, and durability under load.
6309/C5 Bearing Typical Application Areas
This bearing is ideally suited for a variety of industrial machinery and equipment where reliability, speed, and the ability to handle significant radial loads are paramount. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring a robust, high-speed ball bearing solution.
