6310-B Bearing Product Overview & Core Advantages
The 6310-B is a single row deep groove ball bearing designed for robust performance in general industrial applications. This metric bearing excels at handling primarily radial loads and offers reliable operation due to its simple yet effective open design. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution without compromising on fundamental performance and durability. Its open seal type allows for easy re-lubrication and is ideal for applications where external sealing is provided.
Model Code In-Depth Analysis
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6310 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 50 mm bore, 110 mm OD, and 27 mm width. |
| -B | Internal Design / Contact Angle | Indicates a specific internal design, typically signifying a 40° contact angle, which enhances its capability to handle moderate axial loads in one direction in addition to radial loads. |
6310-B Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 13,938 lbf and a static rating of 861 lbf, ensuring longevity under demanding conditions.
- Optimized for Versatility: The "-B" suffix with its 40° contact angle allows the bearing to accommodate combined loads (radial and axial), offering greater application flexibility than a standard deep groove bearing.
- High-Speed Capability: With a limiting speed of 6,000 rpm and a CN radial internal clearance, this bearing is suitable for a wide range of operational speeds commonly found in industrial machinery.
- Precision & Consistency: Manufactured to ABEC 1 (ISO P0) tolerance class, it guarantees consistent running accuracy, low vibration, and smooth operation.
- Material Integrity: All core components—rings, balls, and cage—are made from chrome steel, providing excellent hardness, wear resistance, and dimensional stability across its operating temperature range of -30°C to 120°C.
6310-B Bearing Typical Application Areas
This versatile bearing is commonly specified for:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial and combined load support.
