6305-2RS1/C3VT155B Bearing Product Overview & Core Advantages
The 6305-2RS1/C3VT155B is a single row deep groove ball bearing engineered for high reliability and robust performance in demanding applications. Its sealed construction and metric dimensions make it an ideal choice for machinery requiring protection from contaminants. A key feature is its C3 radial internal clearance, which accommodates thermal expansion for stable operation under varying thermal conditions. Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating of 4631 lbf, ensuring long service life and dependable operation.
6305-2RS1/C3VT155B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6305 | Standard deep groove ball bearing series with 25mm bore, 62mm OD, 17mm width. | Defines the fundamental bearing dimensions and type. |
| 2RS1 | Bearing features contact seals on both sides. | Provides effective protection against contaminants and retains lubricant, enhancing bearing life. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Allows for thermal expansion in applications with high operating temperatures or tight fits, preventing premature failure. |
| VT155B | Vibration level designation. | Indicates the bearing has been manufactured and inspected to meet specific low vibration criteria, suitable for applications requiring smooth and quiet operation. |
6305-2RS1/C3VT155B Bearing Structural Features & Performance Benefits
Robust Sealed Design: The 2RS1 contact seals are a critical structural feature, effectively shielding the bearing's interior from dust, moisture, and other particulate matter. This design ensures the integrity of the internal components, significantly extending the bearing's operational lifespan in harsh environments and contributing to its maintenance-free characteristics.
Optimized Internal Geometry: As a single row deep groove ball bearing, it is designed primarily for high radial load capacity. The deep, continuous raceways and high-quality chrome steel construction provide excellent durability and resistance to wear.
Thermal Stability with C3 Clearance: The C3 radial internal clearance is a key performance enhancer. It provides extra space between the rolling elements and raceways to accommodate shaft and housing expansions due to heat, preventing excessive preload and ensuring smooth, reliable performance at the specified temperature range of -30°C to 120°C.
Precision and Smooth Operation: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing offers consistent dimensional accuracy. Combined with the VT155B vibration level specification, it delivers smooth, low-noise operation, making it suitable for applications where vibration control is important.
6305-2RS1/C3VT155B Bearing Typical Application Areas
The 6305-2RS1/C3VT155B is versatile and finds use across various industries due to its sealed and robust design. Key application areas include:
- Electric Motors and Generators: Ideal for use in standard industrial motors where contamination protection and reliable performance are required.
- Material Handling Equipment: Used in conveyor pulleys, rollers, and gearboxes that operate in dusty or dirty conditions.
- Agricultural Machinery: Suitable for tractors, combines, and other farm equipment exposed to high levels of debris and moisture.
- Industrial Fans and Blowers: Provides dependable service in units that require protection from airborne particles.
- General Industrial Machinery: A reliable component in pumps, compressors, and other machinery where a sealed, pre-lubricated bearing is specified for ease of use and longevity.
