61902-2RS1/W64F Bearing Product Overview & Core Advantages
The 61902-2RS1/W64F is a metric single row deep groove ball bearing engineered for high reliability in compact applications. Its primary advantages stem from its sealed design and integrated solid oil lubrication, making it a maintenance-free solution. This bearing is designed to handle primarily radial loads and is characterized by its low friction, quiet operation, and long service life, even in demanding conditions. The combination of a sealed construction and solid lubricant ensures consistent performance and protection against contamination.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61902 | Basic model number for a metric single row deep groove ball bearing with a 15mm bore, 28mm OD, and 7mm width. |
| 2RS1 | The bearing is fitted with contact seals on both sides. This provides excellent protection against the ingress of contaminants and the egress of lubricant. |
| W64 | Indicates the bearing is pre-lubricated with a solid oil (polymer-based) lubricant. |
| F | Suffix for a specific manufacturing process related to the solid oil filling. |
61902-2RS1/W64F Bearing Structural Features & Performance Benefits
- Sealed for Life & Contamination Resistance: The 2RS1 double-contact seals effectively shield the bearing's internals from dust, dirt, and moisture, significantly enhancing reliability in unclean environments.
- Maintenance-Free Operation: The integrated Solid Oil (W64) lubrication eliminates the need for re-lubrication. This solid polymer lubricant does not leak, resists wash-out, and provides stable performance across the specified temperature range (-30°C to +120°C).
- Robust Construction: Manufactured entirely from chrome steel for the rings, balls, and cage, this bearing offers high strength and durability, suitable for a radial dynamic load rating of 980 lbf.
- Precision & Quiet Running: Built to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, it ensures smooth and quiet operation, making it ideal for applications requiring low noise and vibration.
61902-2RS1/W64F Bearing Typical Application Areas
- Small Electric Motors (e.g., cooling fans, appliance motors)
- Office Automation Equipment (printers, scanners, copiers)
- Medical Devices and Low-Power Instrumentation
- Food Processing and Packaging Machinery (where leak-free lubrication is critical)
- Conveyor Idler Rolls and Other Material Handling Components
