6338 M/C3HVQ6391 Bearing Product Overview & Core Advantages
The 6338 M/C3HVQ6391 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. Engineered to primarily handle radial loads, this bearing features a C3 radial internal clearance and an open design, making it suitable for applications with thermal expansion considerations. Its high dynamic and static load ratings ensure reliable operation under significant stress, while the machined metal cage provides stability at moderate speeds. This bearing is an excellent choice for applications requiring a balance of high load capacity and operational reliability.
6338 M/C3HVQ6391 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6338 | Standard bore diameter (190 mm), outside diameter (400 mm), and width (78 mm) dimensions. |
| M | Indicates a machined metal cage, typically brass or steel, offering high strength and suitability for higher operating temperatures. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications where thermal expansion of the shaft and housing is expected, preventing preload and potential bearing failure. |
| HVQ6391 | A manufacturer's internal designation, often referring to a specific cage design, material variant, or special manufacturing process that enhances performance. |
6338 M/C3HVQ6391 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and robust construction deliver high radial dynamic and static load ratings (83404 lbf and 96668 lbf respectively), enabling the bearing to withstand heavy loads and shock conditions.
- Optimized for Thermal Expansion: The C3 radial clearance is a critical feature, allowing for axial displacement caused by thermal expansion in the surrounding components, thus preventing binding and ensuring smooth operation.
- Stable High-Speed Operation: The machined metal cage (M) provides excellent guidance for the balls, ensuring stability and controlled operation at the specified limiting speed.
- Versatile Application Range: Constructed from chrome steel for both rings and balls, the bearing operates effectively within a wide temperature range of -30°C to 120°C.
- Precision and Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class, it guarantees consistent performance and interchangeability for general precision applications.
6338 M/C3HVQ6391 Bearing Typical Application Areas
This bearing is ideally suited for a variety of heavy-duty and industrial machinery, including:
- Industrial Gearboxes
- Electric Motors and Generators
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Construction Equipment
- Vibrating Screens and other machinery requiring C3 clearance
