6208-Z/C3S0 Bearing Product Overview & Core Advantages
The 6208-Z/C3S0 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing excels in handling significant radial loads while offering moderate axial load capacity. Its key advantages include a shielded design for contaminant protection, a generous C3 radial internal clearance suitable for applications with thermal expansion, and high-quality chrome steel construction throughout for durability and long service life. The combination of a high dynamic load rating and ABEC 1 precision makes it a reliable and cost-effective solution for a wide range of machinery.
6208-Z/C3S0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6208 | Standard bore diameter (40 mm), outside diameter (80 mm), and width (18 mm) dimensions. | Ensures interchangeability and easy replacement. |
| -Z | One side shielded. | Protects bearing internals from dust and debris while allowing for high-speed operation. |
| /C3 | Greater than normal radial internal clearance. | Accommodates shaft and housing fits, and thermal expansion, preventing premature failure due to preload. |
| S0 | Standard cage design and material (Chrome Steel). | Provides reliable performance and strength under standard operating conditions. |
6208-Z/C3S0 Bearing Structural Features & Performance Benefits
- Shielded Design: The single shield (Z) effectively retains the factory-applied lubricant and excludes larger particulate contaminants, enhancing bearing life in dirty environments without the added friction of contact seals.
- Optimized Internal Geometry: The deep groove raceway and high-quality chrome steel balls are engineered for smooth operation and efficient distribution of radial loads, contributing to the high dynamic load rating of 6542 lbf.
- C3 Radial Clearance: This feature is critical for applications where thermal expansion of the shaft or housing is expected. It prevents excessive preload and associated heat buildup, ensuring stable operation across the specified temperature range of -30° to 150 °C.
- Robust Construction: The use of chrome steel for all critical components (rings, balls, cage) ensures high hardness, wear resistance, and consistent performance under the specified limiting speed of 8,300 rpm.
6208-Z/C3S0 Bearing Typical Application Areas
The 6208-Z/C3S0 is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators: A common choice for supporting motor shafts, handling radial loads with high reliability.
- Industrial Gearboxes and Transmissions: Used in various stages to support gears and shafts.
- Material Handling Equipment: Ideal for conveyor pulleys, rollers, and fans.
- Agricultural Machinery: Suitable for applications in tractors, combines, and other farm equipment requiring durable bearings.
- General Industrial Machinery: A standard solution for pumps, blowers, and other machinery where cost-effective, shielded ball bearings are specified.
