6305-2RS2/C3HHT Bearing Product Overview & Core Advantages
The 6305-2RS2/C3HHT is a metric single row deep groove ball bearing engineered for high reliability in demanding applications. Its primary advantage lies in its sealed design and optimized internal geometry, enabling it to handle significant radial loads while offering protection against contamination. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing provides consistent performance and is an excellent choice for general industrial use where robustness and longevity are key.
6305-2RS2/C3HHT Bearing Model Code Explained, Specifications & Naming Convention
| Model Suffix | Technical Meaning | Benefit |
|---|---|---|
| 2RS2 | Contact seals on both sides | Provides superior protection against dust, dirt, and moisture ingress, extending bearing service life. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or where fits cause a reduction in internal clearance. |
| HHT | Heat stabilized up to 120°C | Ensures dimensional stability and maintains performance over a wide temperature range. |
6305-2RS2/C3HHT Bearing Structural Features & Performance Benefits
The 6305-2RS2/C3HHT incorporates several key structural features that translate directly into performance benefits:
- Deep Groove Raceway & High-Quality Steel: The optimized raceway geometry, combined with chrome steel rings and balls, provides a high radial dynamic load rating of 4631 lbf, ensuring durability under heavy loads.
- Robust Sealing Solution: The 2RS2 contact seals are highly effective at retaining lubricant and excluding contaminants, making the bearing suitable for harsh environments and contributing to its maintenance-free operation.
- Optimized Internal Clearance: The C3 radial internal clearance is ideal for applications with expected thermal expansion, preventing preload and ensuring smooth operation.
- Heat Stabilization (HHT): The heat treatment process allows for reliable operation within a temperature range of -30°C to 120°C, making it versatile for various industrial climates.
