6305-2RS1/W64 Bearing Product Overview & Core Advantages
The 6305-2RS1/W64 is a metric single row deep groove ball bearing engineered for exceptional reliability in demanding applications. Its core advantage lies in its sealed construction and integrated solid lubricant, making it a maintenance-free solution ideal for environments where re-lubrication is difficult or impossible. This bearing is designed to primarily handle radial loads and offers a robust performance profile within a compact cross-section, ensuring long service life and consistent operation under standard conditions.
Model Code Breakdown
| 6305 | Basic series code, indicating a medium-duty, metric deep groove ball bearing with a 25mm bore and 62mm outside diameter. |
| 2RS1 | Signifies the bearing is equipped with two contact seals (one on each side). These seals provide superior protection against contaminants and retain lubricant effectively. |
| W64 | Indicates the bearing is pre-lubricated with a Solid Oil filling. This solid lubricant matrix ensures consistent performance, is leak-proof, and is suitable for a wide temperature range. |
6305-2RS1/W64 Bearing Structural Features & Performance Benefits
Sealed and Lubricated for Life: The combination of contact seals (2RS1) and Solid Oil (W64) creates a completely sealed unit. This design eliminates the need for re-lubrication, prevents lubricant wash-out, and offers excellent resistance to contamination, making it a true maintenance-free bearing.
Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a reliable radial dynamic load rating of 4631 lbf, ensuring durability under continuous operation.
Stable Operational Performance: The bearing conforms to ABEC 1 | ISO P0 tolerance class and features a CN group radial internal clearance, providing a balance of precision, smooth running, and minimal vibration for general industrial applications.
Wide Temperature Suitability: With an operational temperature range from -30°C to 120°C, this bearing is versatile for use in various climates and industrial settings.
6305-2RS1/W64 Bearing Typical Application Areas
The 6305-2RS1/W64 is ideally suited for applications requiring a sealed, long-life, and maintenance-free bearing solution. Common uses include:
- Electric Motors and Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
- Food and Beverage Processing Equipment (where lubricant leakage must be avoided)
- Ventilation Fans and Blowers
