6320-Z Bearing Product Overview & Core Advantages
The 6320-Z is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and smooth operation. This metric bearing features a shielded (Z-type) design on one side, offering protection against contamination while maintaining high-speed capability. Manufactured to P6 tolerance class, it delivers enhanced running accuracy, making it ideal for precision machinery and equipment demanding consistent performance and long service life.
6320-Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Suffix | Technical Meaning | Advantage |
|---|---|---|
| 6320 | Basic designation indicating a single row deep groove ball bearing with a 100mm bore, 215mm OD, and 47mm width. | Defines standard bearing dimensions and type. |
| -Z | Denotes a shielded configuration on one side of the bearing. | Provides effective protection against large particulate contaminants, helping to extend bearing life in dirty environments. |
6320-Z Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The deep groove raceway and robust chrome steel construction enable high radial dynamic load rating (39,117 lbf) and static load rating (31,473 lbf), providing stable support for shafts under significant stress.
- Precision & Speed: Manufactured to P6 tolerance class with a standard CN radial internal clearance, this bearing ensures precise running and low vibration. The stainless steel cage and optimized geometry contribute to a high limiting speed of 4,300 rpm.
- Durability & Low Maintenance: The combination of a shielded design and factory-preloaded grease lubrication creates a sealed, long-life unit that is protected from contaminants and is effectively maintenance-free for the majority of its service life.
- Material Integrity: Components made from high-grade chrome steel (rings and balls) and a stainless steel cage offer excellent resistance to wear and corrosion, ensuring reliability across its specified temperature range of -30°C to 120°C.
6320-Z Bearing Typical Application Areas
This bearing is well-suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring robust radial load support
