6204/VU1021 Bearing Product Overview & Core Advantages
The 6204 is a single row deep groove ball bearing designed for exceptional performance in general industrial applications. This metric bearing excels at handling radial loads and moderate axial loads in both directions. Its open design allows for versatile lubrication options and facilitates high-speed operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and precise rotation, making it a cost-effective solution for a wide range of machinery requiring robust performance.
6204/VU1021 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 62 | Series Code | Indicates a medium-duty, deep groove ball bearing series with a specific dimension ratio. |
| 04 | Bore Diameter Code | Specifies a 20 mm bore diameter (04 * 5 = 20 mm). |
| (No Suffix) | Standard Design | Signifies an open bearing with no seals or shields, and a standard CN radial internal clearance. |
6204/VU1021 Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The deep groove raceway and single row construction are engineered to efficiently support high radial dynamic load ratings of 2878 lbf.
- High-Speed Capability: The open design minimizes friction and heat generation, enabling a limiting speed of 15,000 rpm. The pressed steel cage ensures stability at high rotational velocities.
- Robust Construction: All core components, including rings, balls, and cage, are manufactured from chrome steel, providing high hardness, wear resistance, and long service life.
- Standardized Precision: Conforming to ABEC 1 (ISO P0) tolerance class and standard CN clearance, this bearing offers consistent performance and interchangeability for general applications.
- Versatile Application Range: With an operating temperature range of -30°C to 120°C and no pre-applied lubrication, it can be customized with greases or oils to suit specific environmental conditions.
