6210-2RS1NR/W64 Bearing Product Overview & Core Advantages
The 6210-2RS1NR/W64 is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its defining features include integrated sealing (2RS1) and a snap ring groove (NR) on the outer ring for simplified axial location. The bearing is pre-lubricated with Solid Oil (W64), providing exceptional lubrication life and making it a maintenance-free solution. Designed to primarily handle radial loads, it offers a compact design, consistent performance, and is suitable for a wide operating temperature range, ensuring long service life in various industrial environments.
Model Code Breakdown
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 6210 | Basic designation: 50mm bore, 90mm OD, 20mm width. | Standard bearing dimensions for easy interchangeability. |
| 2RS1 | Contact seals on both sides. | Provides superior protection against contaminants and retains lubricant effectively. |
| NR | Snap ring groove on the outer ring. | Facilitates secure axial positioning within the housing, simplifying assembly. |
| W64 | Solid Oil lubrication. | Eliminates lubricant leakage, offers long-term lubrication, and is ideal for high-speed and vertical shaft applications. |
6210-2RS1NR/W64 Bearing Structural Features & Performance Benefits
The 6210-2RS1NR/W64 combines several key structural features to deliver robust performance:
- Deep Groove Raceway & Single Row Design: Optimized for high radial load capacity and capable of accommodating moderate axial loads in both directions.
- Double-Contact Seals (2RS1): These low-friction contact seals provide excellent exclusion of contaminants like dust and moisture, significantly extending bearing service life in harsh environments.
- Solid Oil Filling (W64): The bearing cavity is filled with a polymer matrix saturated with oil. This technology prevents oil leakage, ensures consistent lubrication at high speeds (up to 7,100 rpm), and supports a wide operating temperature range from -30°C to 120°C.
- Snap Ring Groove (NR): This feature on the outer ring allows for secure axial location, reducing the complexity and cost of the surrounding housing design.
- Standard ABEC 1 (P0) Tolerance: Provides reliable and consistent running accuracy for a vast range of general industrial applications.
6210-2RS1NR/W64 Bearing Typical Application Areas
This versatile and sealed bearing is ideally suited for applications requiring reliability and minimal maintenance, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- Food and Beverage Processing Equipment (where seal integrity is critical)
