61903-2RS1/W64L Bearing Product Overview & Core Advantages
The 61903-2RS1/W64L is a metric single row deep groove ball bearing engineered for exceptional performance in compact, high-precision applications. Its defining feature is the integrated Solid Oil lubrication system, which provides long-lasting, maintenance-free operation. This bearing is designed to handle primarily radial loads with high efficiency and reliability. Manufactured to ABEC 1 (ISO P0) tolerance standards, it offers consistent performance and is an ideal solution for applications demanding compact design, low maintenance, and reliable operation within a standard temperature range.
61903-2RS1/W64L Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| -2RS1 | Contact Seals on Both Sides | Provides superior protection against contamination and retains lubricant effectively, enhancing bearing life in dusty or humid environments. |
| /W64L | Solid Oil Lubrication | A polymer matrix saturated with oil, offering a maintenance-free solution with minimal leakage, ideal for life-long lubrication or hard-to-reach applications. |
61903-2RS1/W64L Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built with chrome steel rings, balls, and cage, this bearing offers high strength and durability. Its deep groove raceway geometry is optimized to handle significant radial dynamic and static loads (1039 lbf / 573 lbf).
- Maintenance-Free & Long Service Life: The combination of contact seals (2RS1) and Solid Oil lubrication (W64L) creates a sealed, pre-lubricated system. This eliminates the need for re-lubrication, prevents lubricant washout, and protects against contaminants, ensuring a long, reliable service life.
- Precision & Smooth Operation: Manufactured to ABEC 1 precision with a standard CN radial internal clearance, this bearing ensures smooth, low-vibration, and low-noise operation, making it suitable for a wide range of general precision applications.
- Wide Operating Temperature Range: The Solid Oil lubrication and material selection allow for a functional temperature range from -30°C to +120°C, providing versatility for various operating conditions.
61903-2RS1/W64L Bearing Typical Application Areas
- Small Electric Motors (e.g., cooling fans, appliance motors)
- Precision Gearboxes and Drives
- Office Automation Equipment (printers, scanners)
- Medical Devices and Instrumentation
- Food Processing Machinery (where maintenance-free operation is critical)
- Conveyor System Idler Rolls
