6203-2Z/CNHLHT23 Bearing Product Overview & Core Advantages
The 6203-2Z/CNHLHT23 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This shielded bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include a compact design, pre-lubrication for maintenance-free operation, and a standardized metric dimension (17x40x12 mm) for easy integration. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a robust balance of precision and performance for general industrial use.
6203-2Z/CNHLHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6203 | Basic bearing series, defining the standard dimensions (17mm bore, 40mm OD, 12mm width). | Interchangeable, widely available standard size. |
| 2Z | Non-contact steel shields on both sides. | Effective contamination protection while maintaining high-speed capability (up to 17,000 rpm). |
| CN | Standard (Normal) radial internal clearance. | Suitable for most common operating conditions and fits. |
| HL | High Temperature Stabilization treatment. | Ensures dimensional stability for the specified temperature range (-30°C to 120°C). |
| HT23 | High-temperature, synthetic hydrocarbon grease lubricant. | Provides long-lasting lubrication and stable performance across the entire operating temperature range. |
6203-2Z/CNHLHT23 Bearing Structural Features & Performance Benefits
Deep Groove Raceway & Single Row Design: The optimized raceway geometry allows the bearing to accommodate not only significant radial loads (2147 lbf dynamic / 1079 lbf static) but also combined loads, ensuring versatile performance.
Steel Shields (2Z): These non-contact shields provide a highly effective barrier against dust and other contaminants, significantly extending bearing service life without the added friction of contact seals, thereby supporting the high limiting speed.
Pre-lubrication with HT23 Grease: The bearing is factory-filled with a high-temperature grease, making it ready for immediate maintenance-free operation. This is ideal for applications where re-lubrication is difficult or impossible.
All-Chrome Steel Construction: Rings, balls, and cage are manufactured from chrome steel, providing high hardness, wear resistance, and a long operational lifespan under standard loads.
6203-2Z/CNHLHT23 Bearing Typical Application Areas
