61907-2RS1/W64 Bearing Product Overview & Core Advantages
The 61907-2RS1/W64 is a metric single row deep groove ball bearing engineered for high reliability in compact spaces. Its key advantage lies in its sealed design and integrated solid lubricant, making it a maintenance-free solution for applications demanding long service life and consistent performance. This bearing is designed to primarily handle radial loads and is characterized by its precision ABEC 1 (ISO P0) tolerance, ensuring smooth operation and high rotational accuracy.
Model Code In-Depth Breakdown
| 61907 | Basic series designation for a single row deep groove ball bearing with a 35mm bore and 55mm outside diameter. |
| -2RS1 | Indicates the bearing is fitted with two rubber contact seals (RS1 type) on both sides. These seals provide excellent protection against contaminants and retain lubricant effectively. |
| /W64 | Specifies that the bearing is pre-lubricated with Solid Oil (W64). This solid polymer matrix saturated with oil ensures a consistent and long-lasting lubricant supply, ideal for applications where re-lubrication is difficult or impossible. |
61907-2RS1/W64 Bearing Structural Features & Performance Benefits
Robust Sealed Construction: The 2RS1 rubber contact seals provide superior defense against dust, moisture, and other contaminants, significantly extending bearing service life and enhancing operational reliability in harsh environments.
Maintenance-Free Operation: The integration of Solid Oil (W64) eliminates the need for re-lubrication. This solid lubricant does not leak, is resistant to washout, and performs consistently across the specified temperature range of -30°C to 120°C.
High Load Capacity & Precision: Manufactured from chrome steel for both rings and balls, this bearing offers a dynamic load rating of 2428 lbf and a static load rating of 1754 lbf. The CN radial internal clearance and ABEC 1 precision class ensure smooth, low-vibration, and high-accuracy rotation.
Compact & Lightweight Design: With a cross-section of just 10mm in width and a weight of only 0.08 kg, it is an ideal choice for applications where space and weight savings are critical.
61907-2RS1/W64 Bearing Typical Application Areas
The 61907-2RS1/W64 is ideally suited for a wide range of applications requiring a sealed, maintenance-free, and compact ball bearing solution. Key industries and equipment include:
- Electric Motors & Generators (especially small to medium-sized)
- Automotive Components (e.g., alternators, idler pulleys, water pumps)
- Food & Beverage Processing Machinery (where washdown or contamination is a concern)
- Material Handling Equipment (conveyor rollers, pulleys)
- Agricultural Machinery
- Ventilation Fans & Blowers
- Office Automation Equipment (printers, copiers)
