61901-2RS1/W64 Bearing Product Overview & Core Advantages
The 61901-2RS1/W64 is a metric single row deep groove ball bearing designed for exceptional reliability in compact applications. This sealed bearing excels in handling radial loads and moderate axial loads in both directions. Its key advantages include a robust Chrome Steel construction, integrated Solid Oil lubrication for maintenance-free operation, and ABEC 1 precision, making it an ideal choice for applications demanding high reliability and long service life in constrained spaces.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61901 | Standard series designation for a single row deep groove ball bearing with a 12mm bore. |
| 2RS1 | Features contact seals on both sides, providing superior protection against contaminants and retaining lubricant. |
| W64 | Indicates the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with oil, offering long-term lubrication and extreme temperature stability. |
61901-2RS1/W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Reliability: Manufactured entirely from Chrome Steel, including rings, balls, and cage, this bearing ensures consistent performance, high durability, and resistance to wear.
- Superior Sealing & Contamination Resistance: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other pollutants, significantly extending bearing life in harsh environments.
- Maintenance-Free Operation & Wide Temperature Range: The integrated Solid Oil (W64) lubrication system eliminates the need for re-lubrication and performs reliably across a broad temperature range from -30°C to 120°C.
- Precision & Smooth Operation: Built to ABEC 1 (ISO P0) tolerance class with standard CN radial internal clearance, this bearing provides smooth running and precise rotation for general applications.
61901-2RS1/W64 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Small Electric Motors (e.g., cooling fans, appliance motors)
- Office Automation Equipment (printers, scanners, copiers)
- Precision Instruments and Medical Devices
- Light-duty Gearboxes and Power Tools
- Automotive Auxiliary Units (e.g., idler pulleys, small pumps)
