6320 Bearing Product Overview & Core Advantages
The 6320 metric ball bearing is a high-performance single row deep groove ball bearing engineered for reliable operation under substantial radial loads. Manufactured to ABEC-1 precision tolerances, this open-type bearing delivers consistent performance and long service life in a wide range of industrial applications. Its robust construction from chrome steel components ensures high durability and resistance to wear, making it a dependable choice for demanding environments.
6320 Bearing Model Code Explained, Specifications & Naming Convention
| Code Element | Technical Meaning |
|---|---|
| 63 | Bearing series designation, indicating a medium width and robust load-carrying capacity. |
| 20 | Bore diameter code. For a 63 series bearing, this corresponds to a 100 mm bore diameter. |
| Open | No seals or shields, allowing for high-speed operation and enabling customized lubrication regimes. |
6320 Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway and high-grade chrome steel construction provide excellent radial dynamic load rating of 38,892 lbf and a static load rating of 31,698 lbf, enabling it to handle heavy-duty applications.
- Precision Performance: Built to ABEC-1 tolerance class with a standard CN radial internal clearance, this bearing ensures smooth, low-vibration, and precise rotation, which is critical for maintaining equipment accuracy.
- Optimized for Speed: The stainless steel cage provides high strength and stability, contributing to a limiting speed of 2,800 rpm. The open design reduces friction and heat generation at high rotational speeds.
- Robust Material Selection: Rings and balls made from chrome steel (AISI 52100 equivalent) offer high hardness and fatigue resistance. The stainless steel cage provides excellent corrosion resistance and cage integrity.
- Flexible Lubrication: As an open bearing, it requires lubrication, allowing engineers to select the optimal grease or oil for specific operating conditions, including the specified temperature range of -30°C to 110°C.
6320 Bearing Typical Application Areas
This versatile 6320 ball bearing is ideally suited for a multitude of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural and Construction Machinery
- General Industrial Machinery requiring reliable, heavy-duty radial support.
