6217/C3W64 Bearing Product Overview & Core Advantages
The 6217/C3W64 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing is characterized by its robust radial load capacity and optimized design for reliable operation. A key feature is its C3 radial internal clearance, which accommodates thermal expansion in applications with elevated operating temperatures or heavy loads. Pre-lubricated with Soild Oil, it offers long-term, maintenance-free service, making it an ideal choice for applications where re-lubrication is difficult or impossible. Its open design ensures low friction and high-speed capability, while the ABEC 1 (ISO P0) tolerance class guarantees consistent and dependable performance.
6217/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6217 | Standard designation for a single row deep groove ball bearing with an 85mm bore and 150mm OD. | Indicates standard dimensions for easy interchangeability and sourcing. |
| C3 | Specifies a greater than normal radial internal clearance. | Prevents binding under thermal expansion, ideal for high-temperature or high-load conditions. |
| W64 | Designates the bearing is pre-lubricated with Soild Oil. | Provides lifelong lubrication, eliminates maintenance, and prevents contamination. |
6217/C3W64 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove construction, combined with high-quality chrome steel rings and balls, provides a high radial dynamic load rating of 18884 lbf and a radial static load rating of 13916 lbf, ensuring stable operation under significant stress.
- Optimized for Speed & Temperature: The open seal type minimizes friction, contributing to a high limiting speed of 4,300 rpm. The C3 clearance is critical for maintaining performance in applications where operational heat is generated.
- Maintenance-Free Longevity: The integrated Soild Oil lubrication system operates effectively within a temperature range of -30°C to 120°C, offering reliable, long-term performance without the need for re-lubrication.
- Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance standards, this bearing ensures smooth running and precise rotation, reducing vibration and noise.
