61911-2RS1 Bearing Product Overview & Core Advantages
The 61911-2RS1 is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable operation and precise rotation. Engineered with sealed construction and manufactured to P6 tolerance class, this bearing offers exceptional dimensional accuracy and running precision. Its primary advantage lies in its ability to efficiently handle radial loads while providing robust protection against contamination, making it an ideal choice for applications demanding long service life and minimal maintenance.
61911-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61911 | Basic bearing series, indicating a deep groove ball bearing with a 55mm bore, 80mm OD, and 13mm width. |
| 2RS1 | Contact seals on both sides, providing superior protection against contaminants and retention of lubricant. |
61911-2RS1 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class with strict dimensional control (bore: -0.012mm to 0, OD: -0.011mm to 0), ensuring smooth, precise, and vibration-free operation for demanding applications.
- Robust Sealing: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, significantly extending bearing life and reliability in harsh environments.
- Optimized Material Construction: Components made from chrome steel (rings and balls) and a stainless steel cage offer excellent durability, corrosion resistance, and stable performance across the specified temperature range (-30° to 120 °C).
- Ready-to-Use Lubrication: Pre-lubricated with grease, the bearing is maintenance-free for its entire service life under normal operating conditions, reducing downtime and operational costs.
61911-2RS1 Bearing Typical Application Areas
The 61911-2RS1 is widely used in various industrial sectors and equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
