61820-2RS1/W64 Bearing Product Overview & Core Advantages
The 61820-2RS1/W64 is a metric single row deep groove ball bearing engineered for high performance in compact spaces. Its primary advantage lies in its sealed design and integrated solid lubricant, making it a maintenance-free solution for applications demanding reliability and long service life. This bearing is designed to accommodate primarily radial loads and is characterized by its low friction and high limiting speed, making it suitable for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61820 | Basic bearing series, indicating a single row deep groove ball bearing with specific dimensions (Bore: 100mm, OD: 125mm, Width: 13mm). |
| -2RS1 | The bearing is fitted with contact seals on both sides. The "RS1" designation indicates a specific, high-performance sealing arrangement that provides excellent protection against contamination. |
| /W64 | The bearing is pre-lubricated with Solid Oil. This is a polymer matrix saturated with oil, offering a consistent and long-lasting lubricating film, ideal for applications where re-lubrication is difficult or impossible. |
61820-2RS1/W64 Bearing Structural Features & Performance Benefits
- Sealed & Maintenance-Free Operation: The -2RS1 contact seals effectively shield the bearing internals from dust, moisture, and other contaminants. Combined with the /W64 Solid Oil lubrication, this creates a completely sealed and pre-lubricated system, eliminating the need for maintenance and ensuring consistent performance.
- High Reliability & Long Life: The Solid Oil filling does not leak, is resistant to washout, and provides stable lubrication across the specified temperature range (-30°C to +120°C). This results in exceptional reliability and extended service life, even in harsh environments.
- Optimized for Radial Loads: The single row deep groove construction is primarily designed to support high radial loads (Dynamic: 4002 lbf, Static: 4114 lbf), making it a robust choice for many power transmission applications.
- Precision & Smooth Operation: Manufactured to ABEC 1 | ISO P0 tolerance class with standard CN radial internal clearance, this bearing ensures smooth and quiet running, contributing to the overall efficiency of the assembly.
