6218-2RS1/C3W64 Bearing Product Overview & Core Advantages
The 6218-2RS1/C3W64 is a sealed single row deep groove ball bearing engineered for high reliability in demanding industrial applications. This precision bearing is designed to primarily accommodate radial loads while also handling moderate axial loads in both directions. Its key advantages include a robust sealed construction for contamination protection, a generous C3 radial internal clearance suitable for applications with thermal expansion, and the integration of Solid Oil lubrication for long-term, maintenance-free operation across a wide temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6218 | Basic series code; Single Row Deep Groove Ball Bearing with 90mm bore, 160mm OD, 30mm width. |
| 2RS1 | Contact rubber seals on both sides. Provides superior protection against contaminants and retains lubricant effectively. |
| C3 | Radial internal clearance greater than Normal (CN). Ideal for applications with shaft interference fits or where operational heat generation is expected. |
| W64 | Designates the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with oil, offering a clean and long-lasting lubrication solution. |
6218-2RS1/C3W64 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals effectively shield the bearing's internals from dust, moisture, and other contaminants, significantly extending service life in harsh environments and making it a maintenance-free bearing.
- Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing premature failure due to excessive preload and ensuring smooth running.
- Advanced Solid Lubrication: The integrated Solid Oil (W64) eliminates lubricant leakage, is suitable for a wide temperature range (-30°C to 120°C), and ensures consistent lubrication throughout the bearing's lifespan, even in vertical shaft orientations.
- High-Quality Material & Precision: Manufactured from Chrome Steel for rings, balls, and cage, and built to ABEC 1 | ISO P0 tolerance standards, this bearing delivers reliable performance, high dynamic and static load ratings, and consistent operation.
6218-2RS1/C3W64 Bearing Typical Application Areas
This versatile and durable bearing is ideally suited for a wide range of industrial machinery, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (Conveyors, Pulleys)
