6303-2RSH/C3LHT23 Bearing Product Overview & Core Advantages
The 6303-2RSH/C3LHT23 is a single row deep groove ball bearing designed for exceptional reliability in demanding industrial applications. Engineered with integrated seals (2RS) and a C3 radial internal clearance, this bearing excels at handling radial loads while offering protection against contamination. Its metric dimensions (17mm bore, 47mm OD, 14mm width) and ABEC 1 precision make it ideal for applications requiring consistent performance and high rotational stability.
6303-2RSH/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6303 | Basic bearing series: Deep Groove Ball Bearing with standard dimensions (17×47×14mm) |
| 2RS | Double Contact Seals: Provides effective protection against contaminants from both sides |
| H | Enhanced Seal Design: Improved sealing performance and durability |
| C3 | Radial Internal Clearance: Greater than normal clearance for thermal expansion in high-temperature applications |
| LHT23 | High-Temperature Grease: Special lubricant suitable for -30°C to 120°C temperature range |
6303-2RSH/C3LHT23 Bearing Structural Features & Performance Benefits
Optimized Seal Design: The double-contact rubber seals (2RSH) provide superior protection against moisture, dust, and other contaminants, significantly extending bearing service life in harsh environments.
Enhanced Load Capacity: Manufactured from chrome steel throughout (rings, balls, and cage), this bearing delivers reliable radial load capacity (3057 lbf dynamic, 1495 lbf static) with consistent performance under various operating conditions.
Thermal Stability: The C3 clearance accommodates thermal expansion in applications where temperature variations occur, preventing premature failure due to excessive preload.
Maintenance-Free Operation: Pre-lubricated with high-temperature grease (LHT23) and sealed for life, this bearing requires no relubrication, reducing maintenance costs and downtime.
