6204-2RS1/C3/LT20 Bearing Product Overview & Core Advantages
The 6204-2RS1/C3/LT20 is a metric single row deep groove ball bearing designed for reliable performance in demanding applications. Its sealed construction provides robust protection against contaminants, while the C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used. This bearing excels at handling high radial loads and offers smooth operation, making it an excellent choice for general industrial machinery requiring durability and consistent performance.
6204-2RS1/C3/LT20 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6204 | Basic designation: 20mm bore, 47mm OD, 14mm width | Standard dimensions for easy interchangeability |
| 2RS1 | Double contact rubber seals on both sides | Superior contamination protection, retains lubricant |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, prevents seizure |
| LT20 | Lithium soap base grease with temperature range -30°C to 120°C | Ready-to-use, wide temperature capability |
6204-2RS1/C3/LT20 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables the bearing to handle both radial loads and moderate axial loads in both directions, providing versatile load capacity in a compact design.
Double Rubber Seals (2RS1): These contact seals effectively exclude contaminants such as dust and moisture while retaining the factory-applied lubricant. This construction significantly extends bearing service life in harsh environments and reduces maintenance requirements.
C3 Internal Clearance: The greater radial internal clearance provides operational safety in applications where thermal expansion occurs or where tight interference fits are used, preventing premature failure due to excessive preload.
Pre-lubricated Design: Factory-filled with LT20 grease, the bearing arrives ready for immediate installation and operation across its specified temperature range of -30°C to 120°C, eliminating the need for initial lubrication.
6204-2RS1/C3/LT20 Bearing Typical Application Areas
- Electric Motors: Ideal for small to medium-sized industrial motors requiring reliable sealed bearings
- Industrial Gearboxes: Suitable for various transmission systems where contamination protection is essential
- Material Handling Equipment: Conveyor systems, pulleys, and other machinery in demanding environments
- Agricultural Machinery: Implements and equipment operating in dusty or moist conditions
- Automotive Components: Auxiliary systems, pumps, and accessories requiring sealed bearing solutions
- Ventilation Systems: Fans and blowers where continuous operation and contamination resistance are critical
