6318/C4S1 Bearing Product Overview & Core Advantages
The 6318/C4S1 is a single row deep groove ball bearing engineered for high-performance industrial applications. This metric bearing is characterized by its robust construction and ability to accommodate high radial loads. Its open design allows for versatile lubrication options, while the specified C4 radial internal clearance makes it suitable for applications with thermal expansion considerations or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and precise operation, making it an excellent choice for demanding environments requiring consistent performance.
6318/C4S1 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6318/C4S1 provides key technical specifications:
- 6318: Standard designation for a single row deep groove ball bearing with a 90mm bore, 190mm outside diameter, and 43mm width.
- C4: Indicates a greater radial internal clearance than normal (C0). This is beneficial in applications with significant temperature gradients or where shaft and housing fits result in clearance reduction.
- S1: Designates a specific heat stabilized treatment. This stabilizes the bearing components for operation at elevated temperatures (up to 200°C), reducing the risk of dimensional change and preserving performance.
6318/C4S1 Bearing Structural Features & Performance Benefits
The 6318/C4S1 delivers superior performance through its specific design and material selection:
- High Load Capacity: Built with chrome steel rings, balls, and cage, this bearing offers a high radial dynamic load rating of 32,148 lbf and a radial static load rating of 24,055 lbf, ensuring durability under heavy loads.
- Thermal Stability: The S1 heat stabilization allows for reliable operation within a wide temperature range from -30°C to 200°C, preventing performance degradation in high-temperature environments.
- Versatile Application Fit: The C4 clearance provides operational flexibility for applications involving thermal expansion or specific mounting configurations.
- Precision Engineering: Conformance to ABEC 1 | ISO P0 tolerance class guarantees consistent running accuracy and smooth operation.
6318/C4S1 Bearing Typical Application Areas
The combination of high load capacity, thermal stability, and robust construction makes the 6318/C4S1 ideal for a wide range of industrial machinery, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial support
