61819-2RS1 Bearing Product Overview & Core Advantages
The 61819-2RS1 is a single row deep groove ball bearing engineered for exceptional performance in compact spaces. This sealed bearing is designed to handle primarily radial loads with high reliability. Its key advantages include a robust sealed construction that protects against contamination, a high-precision P6 tolerance class for smooth operation, and a wide operating temperature range. This makes it an ideal solution for applications demanding long service life and minimal maintenance.
61819-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61819 | Basic bearing series designation, indicating a metric, single row deep groove ball bearing with a 95mm bore and 120mm outside diameter. |
| 2RS1 | Indicates the bearing is fitted with two rubber contact seals (RS) on both sides. The "1" suffix often denotes a specific seal design, providing excellent protection against dust and moisture ingress while retaining lubricant. |
61819-2RS1 Bearing Structural Features & Performance Benefits
Optimized Sealing for Contaminated Environments: The 2RS1 rubber contact seals are a critical feature, creating an effective barrier that significantly extends bearing life by preventing the entry of contaminants. This makes the bearing suitable for harsh operating conditions.
High Precision and Smooth Operation: Manufactured to a P6 tolerance class, this bearing ensures precise running accuracy, reduced vibration, and consistent performance, which is essential for high-quality machinery.
Robust Load Capacity and Durability: With a dynamic load rating of 4474 lbf and a static load rating of 3957 lbf, the bearing is built to handle significant radial loads. The use of chrome steel for rings and balls, combined with a stainless steel cage, ensures high strength and corrosion resistance.
Maintenance-Free Operation: The bearing is pre-lubricated with grease and sealed for life, requiring no relubrication. This maintenance-free design reduces total cost of ownership.
61819-2RS1 Bearing Typical Application Areas
The 61819-2RS1 is versatile and finds use in a wide range of industries and equipment, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
