6310NR/C3 Bearing Product Overview & Core Advantages
The 6310NR/C3 is a single row deep groove ball bearing engineered for robust radial load capacity and reliable performance in demanding applications. This metric bearing features a snap ring groove on its outer ring for secure axial positioning and simplified installation. Manufactured to ABEC 1 | ISO P0 tolerance standards with C3 radial internal clearance, it accommodates thermal expansion in applications with elevated operating temperatures. The open design allows for custom lubrication strategies, making it suitable for various industrial environments requiring high-speed operation up to 6,000 rpm.

| Code Segment | Technical Meaning |
|---|---|
| 6310 | Basic bearing designation: 50mm bore, 110mm OD, 27mm width |
| NR | Snap ring groove on outer ring for axial positioning |
| C3 | Greater than normal radial internal clearance for thermal expansion |
6310NR/C3 Bearing Structural Features & Performance Benefits
Snap Ring Integration: The outer ring snap ring groove provides secure axial location without requiring complex housing designs, reducing assembly time and cost.
Optimized Internal Clearance: The C3 clearance accommodates shaft and housing fits that create interference, as well as thermal expansion in high-temperature applications, preventing premature failure.
High-Speed Capability: With a limiting speed of 6,000 rpm and precision chrome steel construction, this bearing maintains stability and reliability in high-velocity applications.
Superior Load Capacity: The single row deep groove design delivers excellent radial load rating (13,938 lbf dynamic) while accommodating moderate axial loads in both directions.
6310NR/C3 Bearing Typical Application Areas
- Electric Motors and Industrial Gearboxes requiring secure axial positioning
- Agricultural Machinery and Construction Equipment with vibration and thermal challenges
- Material Handling Systems including conveyor pulleys and rollers
- Pump Applications where thermal expansion must be accommodated
- Automotive Components requiring reliable bearing performance with simplified mounting
