6304-2RSH/LHT23 Bearing Product Overview & Core Advantages
The 6304-2RSH/LHT23 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing excels at handling significant radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a robust construction for high rigidity, extended service life due to integrated sealing and lubrication, and consistent performance across a wide temperature range, making it a versatile and dependable choice for industrial machinery.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Standard bearing series designation, indicating a medium-duty, metric deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| 2RSH | The bearing is fitted with two contact seals (RSH type) on both sides. These seals provide superior protection against contaminants compared to non-contact shields, enhancing bearing longevity in harsh environments. |
| LHT23 | The bearing is pre-lubricated with LHT23 high-performance grease. This grease is specifically formulated for a wide temperature range (-30°C to +120°C), offering excellent stability and long-term lubrication, contributing to the bearing's maintenance-free characteristics. |
6304-2RSH/LHT23 Bearing Structural Features & Performance Benefits
- Robust Construction & High Rigidity: Manufactured from chrome steel for rings, balls, and cage, this bearing ensures high dimensional stability and resistance to deformation under load, providing reliable and rigid support for rotating shafts.
- Optimized Load Capacity: The deep groove raceway and single-row design are engineered to efficiently support high radial dynamic and static loads (3574 lbf / 1765 lbf), while also handling moderate axial loads from either direction.
- Enhanced Sealing & Contamination Resistance: The 2RSH contact seals effectively exclude moisture, dust, and other particulate contaminants, significantly extending the bearing's operational life in dirty or wet conditions.
- Maintenance-Free Operation: The combination of high-quality contact seals and factory-applied LHT23 grease creates a sealed, lubricated-for-life system, eliminating the need for re-lubrication and reducing maintenance costs.
6304-2RSH/LHT23 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial applications requiring robust and reliable performance, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (Conveyors, Fans)
- Agricultural Machinery
- Automotive Components (Alternators, Water Pumps)
