6318/C3S1 Bearing Product Overview & Core Advantages
The 6318/C3S1 is a single row deep groove ball bearing engineered for superior performance in demanding industrial applications. This metric bearing is characterized by its high radial load capacity and robust construction, making it an ideal solution for machinery requiring reliable and durable rotational support. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent operation and extended service life. Its optimized internal geometry and C3 radial internal clearance make it particularly suitable for applications with thermal expansion or where interference fits are used.
6318/C3S1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6318 | Standard designation for a single row deep groove ball bearing with a 90mm bore, 190mm OD, and 43mm width. |
| C3 | Indicates a greater than normal radial internal clearance. This is essential for applications involving thermal expansion, high speeds, or heavy interference fits. |
| S1 | Signifies a stabilized bearing for high-temperature operation up to 200°C, ensuring dimensional stability under thermal stress. |
6318/C3S1 Bearing Structural Features & Performance Benefits
- High Load Capacity: With a dynamic radial load rating of 32,148 lbf and a static radial load rating of 24,055 lbf, this bearing is built to handle significant radial forces in continuous operation.
- Optimized for High-Speed Operation: The limiting speed of 3,600 rpm is supported by a precision-machined chrome steel cage that minimizes friction and maintains ball alignment.
- Robust Material Construction: All critical components—rings, balls, and cage—are manufactured from high-grade chrome steel, providing excellent hardness, wear resistance, and fatigue life.
- Wide Temperature Range & Stability: The S1 designation ensures reliable performance across a broad temperature range from -30°C to 200°C, making it suitable for diverse operating environments.
- Open Design for Custom Lubrication: The open seal type allows for the application of specialized lubricants tailored to specific operational needs, such as extreme temperatures or contamination control.
