61820-2RZ/W64 Bearing Product Overview & Core Advantages
The 61820-2RZ/W64 is a single row deep groove ball bearing designed for reliable performance in compact spaces. This metric bearing features a sealed construction with Solid Oil lubrication, making it a maintenance-free solution ideal for applications requiring consistent operation with minimal intervention. Its key advantages include the ability to handle significant radial loads, excellent operational stability due to its precision ABEC 1 | ISO P0 tolerance class, and a wide operating temperature range from -30°C to 120°C, ensuring versatility across various environments.
61820-2RZ/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 61820 | Basic designation for a single row deep groove ball bearing with a 100mm bore, 125mm outside diameter, and 13mm width. |
| 2RZ | Indicates the bearing is sealed on both sides with non-contact rubber seals (RZ type). This provides effective protection against contaminants. |
| W64 | Specifies that the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with oil. This offers long-term lubrication and is ideal for preventing lubricant washout. |
61820-2RZ/W64 Bearing Structural Features & Performance Benefits
Sealed & Lubricated for Life: The combination of 2RZ seals and W64 Solid Oil creates a robust, maintenance-free system. The seals effectively exclude dust and moisture, while the Solid Oil ensures consistent lubrication over a long service life, even in challenging conditions where traditional grease might be displaced.
High Load Capacity & Rigidity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating of 4002 lbf and a radial static load rating of 4114 lbf. The single row deep groove raceway and robust chrome steel cage contribute to its overall rigidity and reliable performance under load.
Precision for Smooth Operation: Built to ABEC 1 | ISO P0 tolerance standards with a standard CN radial internal clearance, this bearing ensures smooth running and low vibration, making it suitable for a wide range of general precision applications.
61820-2RZ/W64 Bearing Typical Application Areas
- Electric Motors: Ideal for small to medium-sized motors requiring sealed, long-life bearings.
