6304-2RS2/CNHHT Bearing Product Overview & Core Advantages
The 6304-2RS2/CNHHT is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its core strength lies in its ability to efficiently handle radial loads while offering a compact design. The integrated sealed construction provides robust protection against contaminants, ensuring long service life and making it an ideal choice for applications requiring high reliability and minimal maintenance.
6304-2RS2/CNHHT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2RS2 | Contact rubber seals on both sides | Provides superior sealing effectiveness against dust and moisture compared to non-contact shields, enhancing bearing life in contaminated environments. |
| CN | Normal radial internal clearance | Standard clearance suitable for most common operating conditions and fits. |
| HHT | High-temperature stability treatment | Stabilizes the bearing components, allowing for a consistent and extended operational temperature range up to 120°C. |
6304-2RS2/CNHHT Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The single row design with deep, continuous raceways is engineered for high-capacity radial load handling, ensuring smooth rotation and low vibration.
Robust Sealing Solution: The 2RS2 contact seals are a critical feature, effectively excluding contaminants and retaining lubricant. This design significantly contributes to the bearing's maintenance-free characteristic and long-term reliability in harsh conditions.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing guarantees consistent dimensional accuracy and running performance, which is essential for the smooth operation of machinery.
High-Temperature Capability: The HHT suffix indicates that the bearing components have undergone a special stabilization process. This treatment allows the bearing to maintain dimensional stability and performance across its specified temperature range of -30°C to 120°C.
6304-2RS2/CNHHT Bearing Typical Application Areas
- Electric Motors: A primary application due to its ability to handle radial loads at moderate speeds with sealed protection.
- Industrial Gearboxes: Used in various stages for supporting shafts and transmitting power reliably.
- Agricultural Machinery: Ideal for pumps, conveyors, and other equipment operating in dusty and demanding environments.
- Material Handling Equipment: Found in conveyor rollers, pulleys, and fans where reliability and contamination resistance are key.
- General Industrial Machinery: A versatile choice for a wide range of applications requiring a robust, sealed, and standard-precision ball bearing.
