61808-2RS1 Bearing Product Overview & Core Advantages
The 61808-2RS1 is a metric single row deep groove ball bearing designed for high-precision applications requiring reliable performance in compact spaces. Its key advantage lies in its ability to efficiently support radial loads, making it an ideal choice for applications demanding smooth operation and long service life. The bearing features integrated contact seals (2RS1) and is pre-lubricated with grease, offering a robust, maintenance-free solution. Manufactured to a P6 tolerance class, it ensures high running accuracy and is suitable for high-speed operation up to 7,500 rpm.
61808-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61808 | Basic bearing series designation, indicating a deep groove ball bearing with a 40mm bore, 52mm OD, and 7mm width. |
| 2RS1 | Signifies that the bearing is equipped with two NBR contact seals on both sides. These seals provide superior protection against contaminants and retain lubricant effectively. |
61808-2RS1 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is precision-engineered to handle significant radial loads (Dynamic: 1009 lbf / Static: 843 lbf), ensuring stable operation under demanding conditions.
- Sealed & Pre-Lubricated Design: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants while retaining the factory-applied grease. This creates a maintenance-free system ideal for applications where re-lubrication is difficult.
- High-Speed Capability: The combination of a low-friction stainless steel cage, high-grade chrome steel components, and optimized grease allows for a high limiting speed of 7,500 rpm.
- Precision & Rigidity: Manufactured to P6 tolerance with a standard CN radial internal clearance, this bearing offers high running accuracy and consistent performance, contributing to overall system rigidity.
