61828-2RS1/W64 Bearing Product Overview & Core Advantages
The 61828-2RS1/W64 is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. Its key advantage lies in its sealed construction and integrated solid lubrication, making it a maintenance-free solution for long service life. This bearing is designed to primarily handle radial loads and is characterized by its compact cross-section, with a width of only 18 mm, enabling space-saving designs. Manufactured to ABEC 1 (ISO P0) tolerance class, it offers consistent quality and dependable operation for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61828 | Basic bearing series designation, indicating a metric, single row deep groove ball bearing with a specific dimension series. |
| 2RS1 | The bearing is fitted with contact seals on both sides. The "RS1" suffix denotes a specific type of Nitrile Rubber (NBR) seal, providing effective protection against contaminants. |
| /W64 | Indicates the bearing is pre-lubricated with Solid Oil. This is a polymer matrix saturated with lubricating oil, offering long-term lubrication and making the bearing maintenance-free. |
61828-2RS1/W64 Bearing Structural Features & Performance Benefits
- Robust Sealing & Contamination Resistance: The 2RS1 double-contact seals effectively shield the internal components from dust, moisture, and other contaminants, significantly enhancing bearing life in harsh environments.
- Maintenance-Free Operation: The integrated Solid Oil (W64) lubrication eliminates the need for re-lubrication. This solid lubricant does not leak, is resistant to washout, and operates reliably across the specified temperature range of -30°C to 120°C.
- High Load Capacity & Durability: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing offers a high radial dynamic load rating of 8768 lbf and a radial static load rating of 10454 lbf, ensuring durability under significant radial stresses.
- Precision & Smooth Operation: Built to ABEC 1 precision with a standard CN radial internal clearance, it provides smooth running and low vibration, suitable for general precision applications.
61828-2RS1/W64 Bearing Typical Application Areas
This versatile and robust bearing is ideally suited for applications requiring a sealed, maintenance-free solution. Common uses include:
- Electric Motors and Small Gearboxes
- Material Handling Equipment such as conveyor rollers
- Agricultural Machinery
- Industrial Fans and Blowers
- Various Automotive Components (e.g., auxiliary units)
