6220-2RS1/W64 Bearing Product Overview & Core Advantages
The 6220-2RS1/W64 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering robust, sealed construction for long-term performance. Pre-lubricated with Solid Oil, this bearing is engineered for maintenance-free operation and consistent performance across a wide temperature range, making it an ideal choice for applications requiring high reliability and minimal upkeep.
6220-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| 6220 | Basic series designation, indicating a single row deep groove ball bearing with a 100mm bore and 180mm outside diameter. |
| -2RS1 | Signifies the bearing is equipped with contact seals on both sides. These seals provide superior protection against contaminants compared to non-contact shields. |
| /W64 | Indicates the bearing is pre-filled with Solid Oil lubrication. This technology eliminates grease leakage and offers a consistent lubricant supply, contributing to the bearing's maintenance-free characteristic. |
6220-2RS1/W64 Bearing Structural Features & Performance Benefits
Robust Sealed Design: The 2RS1 contact seals effectively shield the bearing interior from dust, moisture, and other contaminants, significantly enhancing service life in harsh environments.
Maintenance-Free Operation: The integration of Solid Oil (W64) ensures a permanent and reliable lubrication supply. This eliminates the need for re-lubrication, reduces downtime, and prevents lubricant-related failures.
High Load Capacity & Precision: Manufactured from Chrome Steel with an ABEC 1 (ISO P0) tolerance class, this bearing provides reliable performance under its specified radial dynamic load rating and maintains dimensional stability.
Wide Operating Range: The specified temperature range of -30°C to 120°C and a CN radial internal clearance make it suitable for a variety of industrial conditions.
6220-2RS1/W64 Bearing Typical Application Areas
This bearing is well-suited for applications where sealed and maintenance-free operation is critical. Typical uses include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Food and Beverage Processing Equipment (where compliant seals are advantageous)
