6211-2RS1/C3W64F Bearing Product Overview & Core Advantages
The 6211-2RS1/C3W64F is a sealed deep groove ball bearing designed for reliable performance in demanding applications. This single row bearing excels at handling radial loads while also accommodating moderate axial loads in both directions. Its key advantages include extended service life through integrated sealing and solid lubrication, consistent operation across a wide temperature range, and maintenance-free operation, making it an excellent choice for applications requiring high reliability and reduced maintenance.
6211-2RS1/C3W64F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6211 | Standard deep groove ball bearing series; 55mm bore, 100mm OD, 21mm width | Standard dimensions for easy interchangeability and sourcing |
| 2RS1 | Contact seals on both sides | Superior protection against contaminants and retention of lubricant |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with higher operating temperatures or heavy loads |
| W64 | Solid Oil lubrication | Eliminates leakage, extends relubrication intervals, and is suitable for a wide operating temperature range |
| F | Machined brass cage (typically) | Provides high strength, excellent guidance, and suitability for high-speed applications |
6211-2RS1/C3W64F Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing ensures high strength and durability. The single row deep groove raceway geometry is optimized to handle significant radial dynamic load ratings of 9757 lbf and radial static load ratings of 6609 lbf.
Enhanced Sealing and Lubrication: The 2RS1 contact seals provide an effective barrier against contaminants like dust and moisture, while the W64 Solid Oil filling offers a maintenance-free solution. This combination prevents lubricant washout and ensures consistent performance, contributing to a long operational life.
Optimized for Operational Stability: The C3 radial internal clearance allows for stable operation under varying thermal conditions, preventing preload and potential seizure. The machined brass cage (F suffix) ensures smooth operation at the specified limiting speed of 6,300 rpm.
6211-2RS1/C3W64F Bearing Typical Application Areas
- Electric Motors and Generators: A standard choice for motor shafts requiring sealed, maintenance-free operation.
- Industrial Gearboxes and Transmissions: Used in various stages for supporting shafts under radial loads.
- Material Handling Equipment: Conveyor rollers, pulleys, and other components in demanding environments.
- Agricultural Machinery: Implements and machinery where contamination resistance is critical.
- Pumps and Compressors: For shaft support in units requiring reliable, sealed bearings.
