D/W R4 R-2RS1 Bearing Product Overview & Core Advantages
The R4 R-2RS1 is a sealed miniature ball bearing designed for precision applications requiring reliable performance in compact spaces. This single row deep groove ball bearing excels at handling radial loads while offering protection from contamination. Manufactured entirely from stainless steel, it provides excellent corrosion resistance. Its compact inch-series dimensions (1/4" bore) and sealed construction make it ideal for applications demanding high reliability, low maintenance, and long service life in challenging environments.
D/W R4 R-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| R4 | Bearing series designation, indicating a specific size and load capacity in the inch series. |
| R- | Prefix for a bearing with a flanged outer ring, facilitating secure mounting and alignment. |
| 2RS1 | Indicates the bearing is fitted with contact seals on both sides (2RS). The "1" suffix often denotes a specific seal design, providing effective protection against contaminants and retaining lubricant. |
D/W R4 R-2RS1 Bearing Structural Features & Performance Benefits
- Flanged Design for Easy Installation: The flanged outer ring (R-) simplifies axial location, reduces housing machining costs, and improves mounting stability, enhancing overall system rigidity.
- Effective Sealing with 2RS1 Seals: The double-sided contact seals provide superior protection against dust, moisture, and other contaminants. This ensures the integrity of the pre-applied grease lubrication, leading to a maintenance-free operation throughout the bearing's service life.
- Full Stainless Steel Construction: Rings, balls, and cage are made from stainless steel, offering excellent corrosion resistance and making the bearing suitable for use in humid, washdown, or chemically aggressive environments.
- Precision Performance: Built to P0 tolerance class and standard CN radial internal clearance, this bearing delivers consistent and smooth running for a wide range of general-purpose applications.
