|---|---|---|
| D/W | Manufacturer Series | Designates the product line from a specific manufacturer. |
| R2-6 | Bore & Size Designation | Indicates a 1/8" (0.125") bore diameter with a specific size series. |
| R | Flanged Outer Ring | Signifies the bearing features an integral flange on the outer ring for secure mounting. |
D/W R2-6 R Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing excellent corrosion resistance and making the bearing suitable for harsh environments and washdown applications.
- Flanged Outer Ring: The flange simplifies installation by providing a positive locating surface, ensuring precise axial alignment and reducing the need for complex housing designs.
- High-Speed Capability: With a limiting speed of 80,000 rpm, this bearing is optimized for high-velocity applications. The open design minimizes friction and heat generation.
- Precision Tolerances: Built to ABEC 1 (P0) tolerance class and featuring a standard (CN) radial internal clearance, it ensures smooth and consistent operation in a wide range of applications.
- Lightweight & Compact: Weighing only 0.001 kg, it contributes to reduced inertia in high-speed assemblies, making it ideal for miniature and precision instruments.
D/W R2-6 R Bearing Typical Application Areas
This bearing is ideally suited for applications requiring compact size, high speed, and corrosion resistance.
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors and Gearboxes: Stepper motors, servo motors, and miniature drives.
- Office Automation Equipment: Printers, scanners, and copiers.
- Food and Beverage Machinery: Equipment requiring frequent washdowns due to its stainless steel construction.
- Robotics and Automation: Small joints, actuators, and guidance systems.
