D/W R6 R-2RS1 Bearing Product Overview & Core Advantages
The D/W R6 R-2RS1 is a sealed single row deep groove ball bearing designed for high reliability in demanding applications. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle significant radial loads while the integral contact seals (2RS1) effectively retain lubrication and exclude contaminants, ensuring long service life and maintenance-free operation. This compact and robust bearing is ideal for applications requiring precision, durability, and consistent performance within a wide temperature range.
Model Code Breakdown
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| D/W R6 | Basic Bearing Designation | Standard inch-series deep groove ball bearing with specific bearing dimensions (Bore: 0.375", OD: 0.875", Width: 0.28118"). |
| R- | Flange Design | Indicates the bearing features an outer ring flange (Flange OD: 0.96902"), facilitating secure and simplified mounting. |
| 2RS1 | Sealing System | Specifies double-sided contact seals made of Nitrile Rubber (NBR). This provides superior protection against contaminant ingress and grease leakage compared to non-contact shields. |
D/W R6 R-2RS1 Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and the stainless steel cage, are made from corrosion-resistant stainless steel, ensuring long-term performance in harsh environments and contributing to the bearing's high rigidity.
- Optimized Load Capacity: The deep groove raceway and single-row design are engineered to efficiently support high radial dynamic load ratings (555 lbf), making it suitable for applications with substantial radial forces.
- Integrated Sealing & Lubrication: The 2RS1 contact seals work in tandem with the factory-applied grease lubrication to create a sealed, maintenance-free system. This combination effectively excludes moisture and debris while retaining the lubricant, significantly extending service intervals.
- Precision & Flange Mounting: Manufactured to P0 (ABEC 1) tolerance class with standard radial internal clearance (CN), ensuring reliable and consistent operation. The outer ring flange allows for easy axial location and secure housing fit, simplifying assembly.
D/W R6 R-2RS1 Bearing Typical Application Areas
The D/W R6 R-2RS1 is ideally suited for a wide range of industrial and precision equipment, including:
- Food & Beverage Processing Machinery (conveyors, mixers)
- Medical and Laboratory Equipment (small pumps, analyzers)
- Chemical Handling Pumps
- Agricultural Machinery Components
- Marine and Outdoor Applications (where corrosion resistance is critical)
