6211/C3W64 Bearing Product Overview & Core Advantages
The 6211/C3W64 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This precision bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable operation and consistent performance. A key feature is its Solid Oil lubrication system, which provides long-term lubrication stability and contributes to its maintenance-free characteristics, making it an excellent choice for applications requiring high reliability and extended service intervals.
6211/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6211 | Basic bearing designation indicating a single row deep groove ball bearing with a 55mm bore and 100mm outside diameter |
| C3 | Specifies greater radial internal clearance than normal, suitable for applications with thermal expansion or where interference fits are used |
| W64 | Indicates the bearing is filled with Solid Oil polymer-based lubricant, providing permanent lubrication and contamination protection |
6211/C3W64 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway geometry enables the 6211/C3W64 to efficiently handle significant radial dynamic loads up to 9757 lbf while accommodating combined loads. The robust construction ensures stable operation under varying load conditions.
Enhanced Operational Reliability: Featuring Solid Oil lubrication, this bearing eliminates the need for relubrication and provides excellent protection against lubricant leakage and contamination. The C3 radial clearance accommodates thermal expansion in high-speed applications, reducing the risk of premature failure.
High-Speed Capability: With a limiting speed of 6,300 rpm, this bearing is suitable for high-rotation applications. The precision manufacturing and optimized internal geometry contribute to smooth operation and reduced vibration at elevated speeds.
Material Excellence: Constructed entirely from chrome steel for rings, balls, and cage, the bearing delivers superior strength, wear resistance, and durability across the operating temperature range of -30°C to 120°C.
