61906-2RS1/W64 Bearing Product Overview & Core Advantages
The 61906-2RS1/W64 is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable operation and long service life. This sealed bearing excels in handling primarily radial loads and is characterized by its compact cross-section with a 9mm width. Its key advantages include the integrated Solid Oil lubrication system, which ensures consistent performance across a wide temperature range from -30°C to 120°C, and its compliance with ROHS and REACH environmental standards. The bearing is manufactured to ABEC 1 | ISO P0 tolerance class, making it a cost-effective and robust solution for various industrial applications.
61906-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 61906 | Basic series designation for a single row deep groove ball bearing with a 30mm bore, 47mm OD, and 9mm width. | Defines the standard dimensions and basic type. |
| 2RS1 | Bearing is fitted with contact seals on both sides. | Provides excellent protection against contamination and retains lubricant effectively. |
| W64 | Indicates the bearing is lubricated with Solid Oil. | Enables maintenance-free operation, eliminates oil leakage, and is suitable for a wide temperature range. |
61906-2RS1/W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing offers high strength and durability. With a radial dynamic load rating of 1637 lbf and a static load rating of 1023 lbf, it is well-suited for applications with significant radial forces.
- Superior Sealing & Contamination Resistance: The 2RS1 contact seals on both sides provide a highly effective barrier against dust, dirt, and moisture. This feature is critical for maintaining bearing integrity and longevity in harsh operating environments.
- Maintenance-Free Operation with Solid Oil: The W64 Solid Oil lubrication is a key performance differentiator. This polymer-based lubricant does not leak, does not require replenishment, and performs consistently across the specified temperature range, reducing total cost of ownership.
- Precision & Smooth Operation: Built to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing ensures smooth and quiet running, contributing to the overall efficiency of the assembly.
61906-2RS1/W64 Bearing Typical Application Areas
