D/W R8 R-2RS1 Bearing Product Overview & Core Advantages
The D/W R8 R-2RS1 is a sealed single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its core advantages include the ability to handle significant radial loads, consistent operation across a wide temperature range (-30° to 120 °C), and maintenance-free operation due to its integral seals and pre-applied grease lubrication. This combination makes it ideal for applications demanding long service life and minimal upkeep.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer designation (Dodge/Wallace). |
| R8 | Specific bearing series, defining the internal geometry and dimensions. |
| R- | Prefix for a flanged outer ring design. |
| 2RS1 | Indicates the bearing is fitted with contact seals on both sides (RS), providing superior protection against contaminants. The "1" denotes a specific seal design. |
D/W R8 R-2RS1 Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, ensuring durability and reliable performance in harsh or washdown environments.
- High Load Capacity: Engineered to support a radial dynamic load rating of 994 lbf and a radial static load rating of 531 lbf, making it suitable for applications with significant radial forces.
- Integrated Flange & Sealing: The flanged outer ring (1.2252" outer diameter) facilitates easy mounting and axial location. The 2RS1 double-contact seals effectively retain grease and exclude moisture and debris, enabling maintenance-free operation.
- Precision & Stability: Manufactured to P0 tolerance class with a controlled radial internal clearance (CN), ensuring smooth and precise rotation with minimal vibration.
- Optimized Lubrication: Pre-lubricated with grease suitable for the specified temperature range, contributing to a long service life and a limiting speed of 16,000 rpm.
D/W R8 R-2RS1 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial and precision equipment, including:
- Food & Beverage Processing Machinery (conveyors, mixers)
- Medical and Laboratory Equipment
- Chemical Processing Pumps and Valves
- Precision Electric Motors and Small Gearboxes
- Any application requiring a corrosion-resistant, sealed, and flanged bearing solution.
