6218/C4S1 Bearing Product Overview & Core Advantages
The 6218/C4S1 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. Its primary advantage lies in its optimized design for handling significant radial loads, making it a reliable and cost-effective solution. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures consistent operation and is characterized by its open design and specified C4 radial internal clearance, which accommodates thermal expansion in various operating conditions. Its construction from high-grade Chrome Steel for all core components guarantees durability and a long service life.
6218/C4S1 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 6218 | Standard designation for a single row deep groove ball bearing with a 90 mm bore, 160 mm OD, and 30 mm width. |
| /C4 | Indicates a greater than normal radial internal clearance. This is crucial for applications with significant thermal expansion or where interference fits are used. |
| S1 | Specifies a stabilized heat treatment, allowing the bearing to operate continuously at elevated temperatures up to 200°C. |
6218/C4S1 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and single row design are optimized to support high radial dynamic load ratings (21,604 lbf) and radial static load ratings (16,074 lbf), ensuring reliable performance under heavy loads.
- Thermal Stability: The S1 heat stabilization allows for consistent performance across a wide temperature range from -30°C to 200°C, preventing dimensional changes and premature failure.
- Optimized Internal Clearance: The C4 clearance provides extra space between the rolling elements and raceways, which is essential for applications involving high rotational speeds or thermal gradients, preventing binding and reducing friction.
- Precision Engineering: Conforming to ABEC 1 | ISO P0 tolerance class, this bearing offers precise running accuracy, low vibration, and smooth operation, contributing to overall system efficiency.
- Versatile Open Design: The open seal type allows for easy re-lubrication and is suitable for applications where external sealing is provided or where heat dissipation is a priority.
6218/C4S1 Bearing Typical Application Areas
The 6218/C4S1 is engineered for a broad spectrum of industrial machinery. Its combination of high load capacity, thermal stability, and C4 clearance makes it ideal for:
- Electric Motors and Generators
- Industrial Gearboxes and Transmission Systems
- Material Handling Equipment such as conveyor pulleys
