6315/VA205 Bearing Product Overview & Core Advantages
The 6315 ball bearing is a single row deep groove ball bearing designed for superior performance in demanding applications. Engineered to accommodate primarily radial loads, this open-type bearing offers a robust and reliable solution. Its metric dimensions (75mm bore, 160mm OD, 37mm width) and ABEC 1 (ISO P0) tolerance class make it an excellent choice for general industrial use where high precision is not the primary concern but dependable operation is critical. The bearing is pre-lubricated with a solid lubricant, enabling operation across an exceptionally wide temperature range from -30°C to 350°C.
6315/VA205 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 63 | Bearing Series | Denotes a medium-duty, single row deep groove ball bearing series with optimized internal geometry. |
| 15 | Bore Diameter Code | Indicates a standard 75 mm bore diameter (15 x 5 = 75 mm). |
| Open | Seal Type | No seals or shields, allowing for high-speed operation and easy re-lubrication if required. |
| Solid Lubricant | Lubrication | Pre-lubricated for life, suitable for extreme temperatures and environments where liquid lubricants would fail. |
6315/VA205 Bearing Structural Features & Performance Benefits
- High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing achieves a high radial dynamic load rating of 25,403 lbf and a static load rating of 17,355 lbf, ensuring durability under significant stress.
- Robust Construction: The single row deep groove design, combined with a chrome steel cage, provides a balanced and sturdy structure capable of handling high limiting speeds and offering stable operation.
- Standardized Internal Clearance: The CN radial internal clearance is the standard group, making it suitable for a wide range of common operating conditions and ensuring predictable performance.
- Extreme Environment Suitability: The integration of a solid lubricant is a key feature, granting exceptional performance across a vast temperature range (-30°C to 350°C) where conventional greases would degrade or melt.
6315/VA205 Bearing Typical Application Areas
This versatile ball bearing is engineered for reliability in a broad spectrum of industrial machinery. Its combination of load capacity, speed capability, and high-temperature solid lubrication makes it ideal for:
- Material Handling Equipment: Conveyor rollers, pulley systems.
- Industrial Gearboxes and Transmissions: Supporting shafts in standard-speed reducers.
- Electric Motors and Generators: A common choice for motor shaft support in various power ratings.
- Agricultural Machinery: Applications in tractors, harvesters, and other farm equipment.
- High-Temperature Environments: Ovens, dryers, and other equipment where extreme heat is a factor.
