6308NR/C3 Bearing Product Overview & Core Advantages
The 6308NR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing features a snap ring groove on its outer ring, enabling secure axial positioning within housings without requiring complex machining. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable operation under significant radial loads while maintaining cost-effectiveness for general industrial use.
6308NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 6308 | Basic bearing designation: 40mm bore, 90mm OD, 23mm width | Standard dimensions for interchangeability |
| NR | Snap Ring groove on outer ring | Simplified housing design and secure axial location |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits |
6308NR/C3 Bearing Structural Features & Performance Benefits
Snap Ring Design Advantage: The integrated snap ring groove eliminates the need for separate bearing retention components, reducing assembly time and cost while ensuring reliable axial positioning in the housing.
Optimized Internal Clearance: The C3 clearance provides enhanced operational reliability in applications subject to temperature variations or where press fits create reduced internal clearance during installation.
Robust Load Capacity: With a radial dynamic load rating of 915 lbf and static load rating of 5395 lbf, this bearing handles substantial radial loads in continuous operation.
High-Speed Capability: The limiting speed of 7,500 rpm combined with the open design allows for efficient operation in various industrial machinery.
Material Excellence: Constructed entirely from chrome steel for rings, balls, and cage, ensuring consistent performance and durability across the operating temperature range of -30°C to 120°C.
