6338 M/C3VQ658 Bearing Product Overview & Core Advantages
The 6338 M/C3VQ658 is a single row deep groove ball bearing engineered for demanding industrial applications requiring high radial load capacity and reliable performance. This open-type bearing features a C3 radial internal clearance, making it particularly suitable for applications where thermal expansion or fit conditions necessitate greater internal play. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent precision and is constructed entirely from chrome steel for superior durability and wear resistance.
6338 M/C3VQ658 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6338 | Basic bearing series, defining the standard dimensions: 190mm bore, 400mm OD, 78mm width. |
| M | Indicates a machined metal cage, offering high strength and suitability for high-speed operation. |
| C3 | Specifies a greater than normal radial internal clearance group, ideal for applications with thermal gradients or interference fits. |
| VQ658 | A manufacturer-specific designation, often related to a special manufacturing process or quality inspection standard. |
6338 M/C3VQ658 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry is designed to support high radial dynamic load ratings of 83404 lbf and radial static load ratings of 96668 lbf, making it a robust choice for heavy-duty machinery.
High-Speed Capability: The incorporation of a machined metal cage (M) ensures dimensional stability and guidance of the balls at the limiting speed of 3000 rpm, reducing friction and wear.
Thermal & Fit Adaptability: The C3 radial internal clearance provides operational flexibility in environments with elevated temperatures or where press-fits are used, preventing premature failure due to excessive preload.
Durable Construction: Components made from chrome steel (rings and balls) provide excellent resistance to fatigue and a long operational lifespan under continuous load.
