6309/C4VC486 Bearing Product Overview & Core Advantages
The 6309/C4VC486 is a single row deep groove ball bearing engineered for exceptional radial load capacity and high-speed operation. This precision bearing features a C4 radial internal clearance, making it ideally suited for applications where thermal expansion is a critical factor. Its open design allows for versatile lubrication options, while its ABEC 1 (ISO P0) tolerance ensures reliable performance in a wide range of industrial machinery. The combination of high dynamic and static load ratings with a robust all-chrome steel construction delivers outstanding durability and long service life.
6309/C4VC486 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6309/C4VC486 provides specific technical details:
- 6309: Standard designation for a single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width.
- /C4: Denotes a greater than normal radial internal clearance. This is crucial for applications with significant temperature gradients, preventing preload and ensuring smooth operation.
- VC486: This suffix is a manufacturer-specific code. It typically indicates a specific vibration level or a specialized manufacturing process. For precise interpretation, consulting the manufacturer's technical documentation is recommended.
6309/C4VC486 Bearing Structural Features & Performance Benefits
- Optimized for High Speeds and Loads: The single row deep groove raceway geometry is designed to support high radial loads and moderate axial loads in both directions. With a limiting speed of 6,700 rpm, it is capable of high-velocity applications.
- Thermal Stability with C4 Clearance: The specified C4 radial internal clearance is a key performance feature. It accommodates shaft and housing expansions in high-temperature environments or under high-speed conditions, preventing binding and reducing friction and heat generation.
- Robust Construction for Durability: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing offers high strength, wear resistance, and dimensional stability, contributing to its high dynamic (11,915 lbf) and static (7,194 lbf) load ratings.
- Precision and Versatility: The ABEC 1 precision class guarantees consistent quality and reliable operation. The open seal type provides flexibility for the user to select the most appropriate lubricant for the specific application environment.
6309/C4VC486 Bearing Typical Application Areas
This bearing is widely used in various industrial sectors due to its robust design and high-performance characteristics. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor pulleys)
- Pumps and Compressors
