6003-2RSL/LHT23 Bearing Product Overview & Core Advantages
The 6003-2RSL/LHT23 is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its core advantage lies in its sealed design (2RSL), which provides robust protection against contamination, and its pre-lubrication with LHT23 grease, enabling maintenance-free operation. This bearing is engineered to handle primarily radial loads efficiently and is characterized by its compact dimensions (17mm bore, 35mm OD, 10mm width), making it an ideal choice for applications demanding high reliability and long service life without relubrication.
6003-2RSL/LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| 6003 | Standard bearing series designation indicating metric dimensions (17x35x10mm). | Defines the core bearing size and interchangeability. |
| 2RSL | Contact rubber seals on both sides. | Provides excellent sealing against dust and moisture, retaining lubricant effectively. |
| LHT23 | Lithium soap base grease, suitable for a wide temperature range. | Ensures reliable performance from -30°C to 120°C, offering long-term lubrication. |
6003-2RSL/LHT23 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RSL contact seals are a key structural feature, providing superior protection against contaminants. This significantly enhances bearing life in harsh environments and makes the unit effectively maintenance-free.
- Optimized Lubrication: Pre-filled with LHT23 grease, this bearing is ready for immediate use and delivers consistent performance across its specified temperature range, eliminating the need for initial lubrication.
- Precision & Load Capacity: Manufactured to ABEC 1 | ISO P0 tolerance class with CN radial internal clearance, it ensures smooth and quiet operation. The deep groove raceway and chrome steel construction enable it to handle significant radial dynamic loads (1349 lbf) and radial static loads (731 lbf).
- High-Speed Capability: With a limiting speed of 21,000 rpm, the design is well-suited for applications requiring high rotational velocities.
6003-2RSL/LHT23 Bearing Typical Application Areas
This versatile sealed ball bearing is commonly specified in:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
- Material Handling Equipment
