6338 M/C3VL2071 Bearing Product Overview & Core Advantages
The 6338 M/C3VL2071 is a single row deep groove ball bearing engineered for superior performance in demanding industrial applications. Its primary design focus is on handling significant radial loads with high reliability. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a robust and cost-effective solution for general machinery. A key feature is its specified C3 radial internal clearance, which makes it particularly suitable for applications involving thermal expansion, heavy loads, or where interference fits are used, ensuring optimal performance and extended service life.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6338 | Standard bearing series designation, defining the basic dimensions: 190mm bore, 400mm OD, 78mm width. | Provides a standardized and interchangeable component. |
| M | Indicates a machined metal cage (also known as a pressed steel cage). | Offers high strength, excellent guidance, and suitability for high-speed applications and demanding operating conditions. |
| C3 | Specifies a greater than normal radial internal clearance. | Accommodates thermal expansion from high speeds or heavy loads and interference fits, preventing premature failure due to binding. |
| VL2071 | Manufacturer-specific code, often related to internal production or material lot tracking. | Ensures traceability and consistent quality control. |
6338 M/C3VL2071 Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: The single row deep groove design, combined with chrome steel rings and balls, provides a high radial dynamic load rating of 83,404 lbf and a static load rating of 96,668 lbf. This makes it capable of withstanding significant forces in heavy-duty machinery.
High-Speed Capability with Machined Metal Cage: The inclusion of the machined metal (M) cage provides superior strength and stability, contributing to reliable operation at the bearing's limiting speed. This cage design is ideal for applications requiring a high rotational velocity.
Optimized Internal Clearance for Versatility: The C3 clearance is a critical performance feature. It is engineered for applications where shaft and housing fits, or operational heat, would cause a standard clearance bearing to run too tightly, thus preventing overheating and seizure.
Open Design for Custom Lubrication: As an open bearing (no seals or shields), it allows for the use of specialized lubrication systems. This is advantageous in applications where the bearing is integrated into a centralized lubrication system or operates in high-temperature environments beyond the range of standard pre-greased bearings.
6338 M/C3VL2071 Bearing Typical Application Areas
The 6338 M/C3VL2071 is designed for a wide range of industrial machinery requiring a robust, high-capacity bearing. Its specifications make it well-suited for:
- Industrial Gearboxes and Drives
- Large Electric Motors
- Material Handling Equipment (e.g., conveyor pulleys)
- Construction and Mining Machinery
- Vibrating Screens and Heavy-Duty Fans
- Agricultural Machinery
