6318/S1 Bearing Product Overview & Core Advantages
The 6318 single row deep groove ball bearing is a fundamental component in rotating machinery, engineered for exceptional reliability in radial load applications. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a robust and cost-effective solution for a wide range of industrial uses. Its open design allows for versatile lubrication options, while the high-grade chrome steel construction ensures durability and a long service life, even within a broad operating temperature range.
6318/S1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 63 | Series designation indicating medium duty and specific dimensional proportions. |
| 18 | Bore diameter code. Multiply by 5 to get the bore diameter in mm: 18 * 5 = 90 mm. |
| (No Suffix) | Indicates an open (unsealed) bearing with standard radial internal clearance (CN) and no pre-lubrication. |
6318/S1 Bearing Structural Features & Performance Benefits
- High Load Capacity: The optimized raceway geometry and single row of balls enable high radial dynamic load rating of 32,148 lbf and a radial static load rating of 24,055 lbf, making it suitable for substantial radial forces.
- Versatile Performance: The open seal type allows for the application of various lubricants tailored to specific speed, temperature, and environmental conditions, supporting a limiting speed of 3,600 rpm.
- Robust Construction: All critical components—rings, balls, and cage—are manufactured from chrome steel, providing high hardness, wear resistance, and consistent performance.
- Standardized Precision: Conforms to ABEC 1 | ISO P0 tolerance class and CN radial internal clearance, ensuring reliable interchangeability and smooth operation in most industrial applications.
