61820-2RS1 Bearing Product Overview & Core Advantages
The 61820-2RS1 is a metric single row deep groove ball bearing designed for exceptional performance in compact spaces. Engineered with sealed construction, it offers reliable protection against contaminants and retains lubricant for long service life. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and robust solution for applications demanding high reliability and minimal maintenance. Manufactured to P6 tolerance class, it ensures precision and smooth operation, ideal for high-performance mechanical systems.
61820-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61820 | Basic bearing series, indicating a metric, single row deep groove ball bearing with a 100mm bore, 125mm OD, and 13mm width. |
| 2RS1 | Designates contact-type rubber seals on both sides. The "RS1" suffix indicates a synthetic rubber seal with a steel insert, providing superior sealing effectiveness compared to non-contact shields. |
61820-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The double-sided 2RS1 contact seals effectively exclude contaminants like dust and moisture while retaining the factory-applied grease lubrication. This significantly extends bearing life and enables maintenance-free operation in demanding environments.
- High Load Capacity: The deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 4002 lbf, ensuring dependable performance under substantial loads.
- Precision & Stability: Manufactured to a P6 tolerance class, this bearing offers tighter dimensional control for precise shaft positioning, reduced vibration, and smooth running, contributing to overall system accuracy.
- Durability & Corrosion Resistance: The stainless steel cage offers excellent resistance to corrosion and high-speed capability, while the standard CN radial internal clearance is suitable for a wide range of common operating conditions.
61820-2RS1 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, sealed, and reliable rotary solution. Common uses include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
