6304-2RSH/C3LHT23 Bearing Product Overview & Core Advantages
The 6304-2RSH/C3LHT23 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include robust construction for high rigidity, extended service life due to integrated sealing, and optimized internal clearance for stable operation under varying thermal conditions. Engineered for high precision and consistent performance, it is an ideal choice for applications requiring dependable, long-term operation with minimal maintenance.
6304-2RSH/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6304 | Standard bearing series designation, indicating a medium-duty, metric deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. | Defines core bearing dimensions and series. |
| 2RSH | Contact seals on both sides. The "RSH" suffix indicates high-performance Nitrile Rubber (NBR) seals with steel reinforcements. | Provides superior contamination exclusion and grease retention, enhancing bearing life in dirty environments. |
| C3 | Greater than normal radial internal clearance. | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, preventing preload and ensuring smooth operation. |
| LHT23 | High-temperature, lithium soap thickened grease. Suitable for a wide temperature range (-30°C to +120°C). | Ensures consistent lubrication and performance across a broad operational spectrum, contributing to long-term reliability. |
6304-2RSH/C3LHT23 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The geometry of the raceways is designed for efficient radial load distribution and the accommodation of combined loads, ensuring smooth rotation and reduced stress concentrations.
High-Performance Sealing (2RSH): The double-sided contact seals are a critical feature. They effectively shield the internal components from contaminants like dust and moisture while securely retaining the premium LHT23 grease. This combination results in a maintenance-free design with a significantly extended service interval.
Controlled Internal Clearance (C3): The C3 radial internal clearance is engineered for applications where shaft and housing fits, or operational heat, may reduce the internal clearance. This prevents binding and ensures optimal performance under a wider range of operating conditions.
Precision Manufacturing (ABEC 1 | ISO P0): Manufactured to ABEC 1 precision standards, this bearing offers excellent running accuracy and low noise and vibration levels, making it suitable for a wide array of general industrial machinery.
6304-2RSH/C3LHT23 Bearing Typical Application Areas
The 6304-2RSH/C3LHT23 is versatile and finds use in numerous sectors due to its sealed and pre-lubricated design. Key application areas include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Automotive Components (alternators, idlers)
