6305-2RS1TN9/C3GWF5 Bearing Product Overview & Core Advantages
The 6305-2RS1TN9/C3GWF5 is a sealed single row deep groove ball bearing engineered for high-performance applications requiring reliable operation under significant radial loads. Its design offers a compact and robust solution, characterized by high limiting speeds and consistent performance. A key advantage is its sealed construction with pre-lubrication, which provides effective protection against contaminants and ensures long service life with minimal maintenance, making it ideal for demanding industrial environments.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning |
|---|---|
| 6305 | Basic bearing designation indicating a metric single row deep groove ball bearing with a 25mm bore, 62mm OD, and 17mm width. |
| 2RS1 | Features contact seals on both sides, providing superior protection against dust, moisture, and other contaminants compared to non-contact shields. |
| TN9 | Indicates a glass fiber reinforced nylon cage (polyamide). This cage design contributes to low friction, quiet operation, and is suitable for high-speed applications. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with significant thermal expansion or where interference fits are used. |
| GWF5 | Signifies that the bearing is pre-lubricated with a specific high-quality, lithium-based grease suitable for a wide temperature range and offering good mechanical stability. |
6305-2RS1TN9/C3GWF5 Bearing Structural Features & Performance Benefits
Optimized Raceway and Ball Design: The deep groove raceways and high-precision chrome steel balls are engineered to handle high radial dynamic load ratings (4631 lbf), ensuring durability and long service life.
High-Speed Nylon Cage (TN9): The glass fiber reinforced nylon cage is lightweight and promotes smooth operation at high rotational speeds (limiting speed of 11,000 rpm), reducing centrifugal forces and friction.
Effective Sealing Solution (2RS1): The double-sided contact seals effectively retain the factory-applied grease and exclude contaminants, making the bearing suitable for dirty or humid environments and enhancing its maintenance-free characteristics.
Controlled Internal Clearance (C3): The C3 radial internal clearance accommodates thermal expansion in the shaft and housing, preventing preload and potential bearing seizure in applications with elevated operating temperatures.
