6306-2RS1/C3W64 Bearing Product Overview & Core Advantages
The 6306-2RS1/C3W64 is a sealed single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a high limiting speed, reliable operation across a wide temperature range, and long-term, maintenance-free service life due to its integrated solid lubrication. The C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions.
6306-2RS1/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6306 | Basic bearing designation, indicating a medium series, single row deep groove ball bearing with a 30mm bore. | Standardized dimensions for easy interchangeability and selection. |
| 2RS1 | Contact seals on both sides, made from Nitrile Rubber (NBR). | Provides excellent protection against contaminants and retains lubricant effectively. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Accommodates thermal expansion and interference fits, preventing premature failure. |
| W64 | Solid Oil lubrication, a polymer matrix saturated with oil. | Ensures a consistent lubricant supply, is maintenance-free, and performs well at high speeds. |
6306-2RS1/C3W64 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The geometry of the raceways allows for smooth operation under radial loads and the accommodation of axial loads from both directions, making it a versatile ball bearing solution.
Robust Contact Seals (2RS1): The Nitrile Rubber seals make direct contact with the inner ring, providing a highly effective barrier against dust, moisture, and other contaminants. This significantly enhances bearing life in harsh environments.
Advanced Solid Oil Lubrication (W64): Unlike traditional grease, Solid Oil is a porous polymer saturated with oil. This design eliminates grease leakage, reduces friction, and maintains stable lubrication at the high limiting speed of 9,600 rpm, even under the specified temperature range of -30°C to 120°C.
Wider Internal Clearance (C3): The C3 radial clearance provides operational stability in applications where bearing rings are heated for mounting or where significant operational heat is generated, preventing seizure and reducing noise and vibration.
6306-2RS1/C3W64 Bearing Typical Application Areas
The 6306-2RS1/C3W64 is engineered for reliability in a wide range of industrial machinery. Its sealed and pre-lubricated design makes it ideal for:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (Conveyors, Fans)
- Agricultural Machinery
- Food and Beverage Processing Equipment (where seals prevent contamination)
