6306 TN9/C4VC486 Bearing Product Overview & Core Advantages
The 6306 TN9/C4VC486 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. Its primary strength lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. Manufactured with precision tolerances (ABEC 1 | ISO P0) and featuring a C4 radial internal clearance, this bearing is optimized for applications requiring secure fits and stable operation under varying thermal conditions. The combination of a nylon cage (TN9) and a generous VC486 grease filling ensures smooth, quiet running and extended service life, making it a reliable choice for high-speed and continuous-duty machinery.
6306 TN9/C4VC486 Bearing Model Code Explained, Specifications & Naming Convention
| Code | Interpretation | Technical Significance |
|---|---|---|
| 6306 | Basic Bearing Series & Size | Denotes a medium-duty, single row deep groove ball bearing with a 30mm bore, 72mm OD, and 19mm width. |
| TN9 | Cage Type | Indicates a glass fiber reinforced nylon 66 cage, contributing to low friction, quiet operation, and high-speed capability. |
| C4 | Radial Internal Clearance | Specifies a greater than normal radial internal clearance, suitable for applications with significant thermal expansion or where interference fits are used. |
| VC486 | Lubrication | Signifies the bearing is pre-lubricated with a specific high-performance grease (VC486), offering excellent temperature stability and long-term lubrication. |
6306 TN9/C4VC486 Bearing Structural Features & Performance Benefits
- Optimized Deep Groove Raceway: The geometry of the raceways enables the bearing to support significant radial loads and moderate bidirectional axial loads, providing versatile load-carrying capacity.
- High-Speed Nylon Cage (TN9): The lightweight and robust nylon cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 9,600 rpm, contributing to energy efficiency.
- Precision & Stability (C4 Clearance): The C4 radial internal clearance ensures reliable operation in applications prone to shaft and housing thermal expansion, preventing preload and potential seizure.
- Long-Term Reliability with Grease: The VC486 grease filling provides a maintenance-free solution with a wide operating temperature range (-30°C to 120°C), reducing the need for re-lubrication.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, the bearing delivers high strength, durability, and resistance to wear.
6306 TN9/C4VC486 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
- General industrial machinery requiring a robust, high-speed, and maintenance-free ball bearing solution.
