61804-2RS1/W64L Bearing Product Overview & Core Advantages
The 61804-2RS1/W64L is a single row deep groove ball bearing designed for compact applications requiring high reliability and consistent performance. This sealed bearing excels in handling substantial radial loads and moderate axial loads in both directions. Its key advantages include a solid oil lubrication system for maintenance-free operation and a robust construction that ensures long service life in demanding environments. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides dependable precision for a wide range of industrial applications.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61804 | Standard series designation for a single row deep groove ball bearing with a 20mm bore and 32mm outside diameter. |
| 2RS1 | Indicates contact seals on both sides, providing superior protection against contamination and retention of lubricant. |
| W64L | Specifies the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with lubricating oil, offering long-term, maintenance-free operation. |
61804-2RS1/W64L Bearing Structural Features & Performance Benefits
Optimized Sealing & Lubrication: The 2RS1 contact seals effectively shield the bearing interior from contaminants like dust and moisture, while the W64L Solid Oil ensures consistent lubrication across the entire operating temperature range (-30°C to 120°C), eliminating the need for re-lubrication.
High Load Capacity & Rigidity: The single row deep groove raceway design is optimized to support significant radial dynamic loads (906 lbf) and static loads (522 lbf). The use of high-grade chrome steel for all bearing components (rings, balls, cage) provides excellent structural integrity and wear resistance.
Precision & Speed Performance: Manufactured to ABEC 1 (ISO P0) precision class with a standard CN radial internal clearance, this bearing ensures smooth, low-vibration operation. It is capable of operating at speeds up to 28,000 rpm, making it suitable for high-speed applications.
61804-2RS1/W64L Bearing Typical Application Areas
The 61804-2RS1/W64L is ideally suited for applications where space is limited and reliability is critical. Common uses include:
- Small Electric Motors: Used in fans, pumps, and power tools.
- Precision Instruments: Suitable for medical devices, optical encoders, and measuring equipment.
- Office Automation Equipment: Found in printers, scanners, and copiers.
- Automotive Auxiliary Systems: Applications such as idler pulleys and small alternators.
