6004-2RSH/C3LHT23 Bearing Product Overview & Core Advantages
The 6004-2RSH/C3LHT23 is a sealed single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing is characterized by its ability to efficiently handle radial loads while offering operational reliability. Its sealed construction and C3 radial internal clearance make it an excellent choice for applications requiring protection from contaminants and accommodating thermal expansion. Manufactured from high-grade chrome steel and compliant with ROHS and REACH standards, it delivers durability and consistent performance across a wide temperature range from -30°C to 120°C.
6004-2RSH/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
- 6004: Basic model number denoting a single row deep groove ball bearing with a 20mm bore, 42mm outside diameter, and 12mm width.
- 2RSH: Signifies that the bearing is equipped with two (2) contact seals (RS) on both sides. The "H" indicates the seal material is NBR (Nitrile Butadiene Rubber), offering effective protection against contaminants and moisture.
- C3: Indicates a greater radial internal clearance than the standard CN group. This is beneficial for applications with high rotational speeds or where thermal expansion of the shaft and housing is a factor.
- LHT23: Specifies that the bearing is pre-lubricated with a specific high-temperature grease (LHT23). This grease is suitable for the bearing's specified temperature range and contributes to its long service life and maintenance-free operation.
6004-2RSH/C3LHT23 Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 2113 lbf and a static load rating of 1135 lbf, ensuring reliable performance under significant stress.
Enhanced Sealing for Contamination Resistance: The 2RSH contact seals effectively shield the internal components from dust, dirt, and moisture. This design preserves the integrity of the grease and extends the bearing's operational life in harsh environments.
Optimized for Operational Stability: The combination of C3 internal clearance and LHT23 high-temperature grease allows for stable operation at the specified limiting speed of 17,000 rpm. This setup accommodates thermal expansion and maintains performance, making it suitable for high-speed applications.
Precision and Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures consistent running accuracy and smooth operation, which is critical for the overall efficiency of the machinery it serves.
