61911-2RS1/W64 Bearing Product Overview & Core Advantages
The 61911-2RS1/W64 is a single row deep groove ball bearing engineered for high reliability in demanding applications. This sealed bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its compact design, featuring a 13 mm width and a 55 mm bore, makes it an ideal choice for space-constrained assemblies. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and is pre-lubricated with Soild Oil for long-term, maintenance-free operation.
61911-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 619 | Deep Groove Ball Bearing Series | Standard design for versatile radial load capacity. |
| 2RS1 | Contact Seals on Both Sides | Provides excellent protection against contamination and retains lubricant effectively. |
| W64 | Soild Oil Lubrication | Ensures lifelong lubrication, eliminates relubrication needs, and is suitable for a wide temperature range. |
61911-2RS1/W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing offers high strength and durability. With a dynamic load rating of 3709 lbf and a static load rating of 3147 lbf, it is built to handle significant radial stresses.
- Superior Sealing & Maintenance-Free Operation: The 2RS1 contact seals on both sides effectively shield the bearing interior from dust, moisture, and other contaminants, while securely retaining the integrated Soild Oil lubricant. This design guarantees a long service life without maintenance.
- Optimized for Performance: The combination of a CN radial internal clearance and high-quality Soild Oil lubrication allows for smooth operation and contributes to a high limiting speed of 11,000 rpm.
