6203-2RSH/LHT23 Bearing Product Overview & Core Advantages
The 6203-2RSH/LHT23 is a single row deep groove ball bearing designed for superior performance in demanding applications. Its key advantage lies in its sealed construction and specialized high-temperature grease, enabling reliable operation under radial loads with minimal maintenance. This bearing offers a compact design, high running accuracy from its ABEC 1 precision class, and is engineered for long service life in a wide operating temperature range, making it an excellent choice for applications requiring high reliability and durability.
6203-2RSH/LHT23 Bearing Model Code Explained, Specifications & Naming Convention
- 6203: Standard designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width.
- 2RS: Signifies that the bearing is fitted with contact seals on both sides. These seals provide superior protection against contamination.
- H: Indicates that the bearing is filled with a special synthetic hydrocarbon grease (LHT23).
- LHT23: Denotes the specific type of high-performance grease used, which is suitable for a wide temperature range (-30°C to +120°C).
6203-2RSH/LHT23 Bearing Structural Features & Performance Benefits
Robust Sealed Design: The double-sided contact seals (2RS) effectively retain lubricant and exclude contaminants like dust and moisture, significantly enhancing bearing life and enabling maintenance-free operation in many environments.
Optimized Lubrication: Pre-lubricated with LHT23 grease, this bearing is ready for immediate use and delivers stable performance across its entire specified temperature range, reducing the need for re-lubrication.
High Load Capacity & Precision: Manufactured from chrome steel for both rings and balls, it provides a high dynamic load rating of 2147 lbf and a static load rating of 1079 lbf. The ABEC 1 (ISO P0) tolerance class ensures consistent, high-running accuracy and smooth operation.
Standard Internal Clearance: The CN radial internal clearance is the standard for general applications, providing an optimal balance for fit and thermal expansion.
6203-2RSH/LHT23 Bearing Typical Application Areas
The 6203-2RSH/LHT23 is ideally suited for a wide range of industrial applications where reliability and sealed protection are paramount. Common uses include:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor System Idlers and Pulleys
- Agricultural Machinery
- Food Processing and Packaging Equipment (where seals prevent contamination)
- Various Automotive Auxiliary Drives
