6228 Bearing Product Overview & Core Advantages
The 6228 single row deep groove ball bearing is a precision bearing engineered for high-performance applications requiring exceptional radial load capacity and operational stability. Manufactured to P6 tolerance class, it delivers superior running accuracy. Its open design facilitates direct lubrication and allows for high limiting speeds up to 3,400 rpm. Constructed from high-grade chrome steel, this bearing offers excellent durability and is ideal for demanding industrial environments where reliability is paramount.
6228 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 62 | Deep Groove Ball Bearing Series | Standard series with robust construction for versatile applications. |
| 28 | Bore Diameter Code (140 mm) | Specifies the bearing size with a 140mm bore. |
| Open (Default) | No Seals or Shields | Enables high-speed operation and allows for custom lubrication schemes. |
| P6 | Tolerance Class | Indicates precision manufacturing with tighter dimensional and running accuracy tolerances. |
| CN | Normal Radial Internal Clearance | Standard clearance suitable for most common operating conditions. |
6228 Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The single row deep groove construction and high-quality chrome steel components enable a dynamic load rating of 37,093 lbf and a static load rating of 33,721 lbf, providing reliable performance under significant radial stresses.
- Precision & High-Speed Capability: Manufactured to a P6 tolerance class, this bearing ensures minimal vibration and smooth operation. The open design, combined with a high-quality cage (standard for the series), contributes to its high limiting speed of 3,400 rpm.
- Robust Construction & Dimensional Stability: Made entirely from chrome steel, the bearing exhibits high hardness and wear resistance. Strict dimensional tolerances on the bore diameter, outside diameter, and width guarantee a precise fit and consistent performance.
- Versatile Operating Range: With a temperature range from -30°C to 120°C, this bearing is suitable for a wide array of industrial environments. The standard CN clearance offers a balanced performance for general applications.
6228 Bearing Typical Application Areas
The 6228 bearing is ideally suited for machinery requiring high precision and robust radial load support. Key sectors include:
- Electric Motors and Generators: For supporting rotor shafts where high speeds and radial loads are present.
- Industrial Gearboxes and Transmissions: Providing reliable shaft support in power transmission systems.
- Material Handling Equipment: Used in conveyor pulleys and rollers subject to heavy loads.
- Agricultural Machinery: In applications such as tractor transmissions and PTO shafts.
- General Industrial Machinery: A versatile component for pumps, fans, and other medium to heavy-duty equipment.
