6306-2RS1/C2 Bearing Product Overview & Core Advantages
The 6306-2RS1/C2 is a metric single row deep groove ball bearing engineered for high reliability in demanding applications. Its sealed design (2RS1) provides robust protection against contamination, while the optimized C2 radial internal clearance ensures stable operation across a wide temperature range. This bearing excels at handling high radial loads and moderate axial loads in both directions, making it an ideal choice for applications requiring consistent performance and long service life. Its compact design and precision manufacturing to ABEC 1 | ISO P0 tolerance standards guarantee smooth operation and easy integration into various mechanical assemblies.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6306 | Basic series designation; 30mm bore, 72mm OD, 19mm width | Standardized dimensions for easy replacement and interchangeability |
| 2RS1 | Contact rubber seals on both sides | Superior contamination protection, retains lubricant, extends service life |
| C2 | Radial internal clearance smaller than normal (C2 group) | Reduced noise and vibration, ideal for precision applications with tight fits or moderate temperature variations |
6306-2RS1/C2 Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The 2RS1 double rubber seals effectively shield the bearing interior from dust, moisture, and other contaminants. This design significantly enhances reliability in harsh environments and minimizes the risk of premature failure.
- Optimized Internal Clearance: The C2 radial clearance is precisely controlled to be tighter than standard. This feature is critical for applications requiring high positional accuracy and low running noise, as it minimizes internal play, especially when used in conjunction with interference fits.
- High Load Capacity & Durability: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 6002 lbf and a static load rating of 3372 lbf. This ensures dependable performance under significant radial loads.
- Precision Engineering: Conforming to ABEC 1 (ISO P0) tolerance class, the bearing guarantees consistent dimensional accuracy and smooth rotation, which is essential for reducing friction and energy consumption.
6306-2RS1/C2 Bearing Typical Application Areas
- Electric Motors & Generators: A standard choice for supporting shafts in various AC and DC motors, providing reliable, long-lasting operation.
- Industrial Gearboxes & Transmissions: Used in light to medium-duty gearboxes to support shafts and handle radial forces efficiently.
- Material Handling Equipment: Ideal for conveyor pulleys, rollers, and other components in conveyor systems.
- Agricultural Machinery: Commonly found in pumps, fans, and auxiliary drives requiring sealed and durable ball bearings.
- General Industrial Machinery: Suitable for a wide range of applications including blowers, small machine tool spindles, and office automation equipment.
