6909 2rs Bearing Product Overview & Core Advantages
The 6909 2RS is a single row deep groove ball bearing featuring integral contact seals (2RS). Engineered for reliable performance in demanding applications, this metric bearing delivers robust radial load capacity and is characterized by its compact design. Manufactured to ABEC-1 precision tolerances, it provides consistent operation and is pre-lubricated for immediate use, making it an excellent choice for applications requiring maintenance-free operation and protection from contamination.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6909 | Basic Bearing Series & Size | Denotes a deep groove ball bearing with a 45mm bore, 68mm OD, and 12mm width. |
| 2RS | Double-Sided Contact Seals | Features nitrile rubber (NBR) seals on both sides, providing superior protection against contaminants and moisture retention of lubricant. |
6909 2rs Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove raceway geometry is specifically designed to support high radial dynamic load ratings (3172 lbf), ensuring stable performance under primary radial forces.
Sealed & Lubricated for Life: The inclusion of 2RS seals creates a robust barrier, making the bearing suitable for dirty or humid environments. Pre-lubrication allows for maintenance-free operation throughout the bearing's service life in many applications.
Precision & Durability: Components made from chrome steel (rings and balls) and a stainless steel cage provide high strength, corrosion resistance, and reliable operation within the specified temperature range of -30°C to 110°C.
Standard Internal Clearance: The C0 radial internal clearance (0.006mm to 0.023mm) is suitable for most general applications, providing a balance of quiet operation and thermal stability.
6909 2rs Bearing Typical Application Areas
The 6909 2RS is a versatile component widely used across various industries, including:
- Electric Motors & Gearboxes: For shaft support in small to medium-sized industrial motors.
- Material Handling Equipment: Conveyor rollers, pulleys, and other machinery requiring sealed bearings.
- Agricultural Machinery: Implements and equipment exposed to dust and moisture.
- Industrial Fans & Blowers: Where continuous operation and contamination protection are critical.
- General Machinery: A reliable choice for a wide range of industrial applications demanding a cost-effective, sealed ball bearing solution.
