6204/VA205 Bearing Product Overview & Core Advantages
The 6204 is a metric single row deep groove ball bearing, engineered for outstanding performance in a wide range of industrial applications. Its fundamental design excels at accommodating high radial loads and moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and precise operation. A key feature is its solid lubricant integration, which enables consistent performance across an extensive temperature range from -30°C to 350°C, making it a robust and versatile choice for demanding environments.
6204/VA205 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 62 | Standard Medium Duty Series | Indicates a balanced design optimized for general-purpose use with a favorable load capacity-to-size ratio. |
| 04 | Bore Diameter Code (20 mm) | Specifies the internal diameter, a critical bearing dimension for shaft fitting. |
| Open (No Seal Suffix) | No integral contact seals or shields. | Allows for higher limiting speeds and facilitates custom lubrication schemes if required. |
| (Implied by Spec) | Solid Lubricant | Enables operation in extreme temperatures and vacuum conditions where conventional oils or greases would fail. |
6204/VA205 Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and high-precision chrome steel components (rings, balls, cage) provide a robust and durable structure capable of handling significant radial dynamic load ratings up to 2878 lbf.
- High-Speed Capability: The open design and precision-ground components contribute to a high limiting speed of 15,000 rpm, suitable for various high-speed applications.
- Extended Service Life in Harsh Conditions: The integrated solid lubricant is the cornerstone of its performance, ensuring reliable lubrication from -30°C to 350°C. This makes it ideal for applications where re-lubrication is impossible or where oils/greases would degrade, carbonize, or freeze.
- Precision & Reliability: Conformance to ABEC 1 tolerance class and standard CN radial internal clearance guarantees consistent running accuracy and smooth operation, reducing vibration and noise.
