D/W R09 R Bearing Product Overview & Core Advantages
The D/W R09 R is a precision miniature ball bearing designed for applications requiring exceptional dimensional stability and reliable performance in compact spaces. As a single row radial ball bearing with an open design, it excels in handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for demanding environments. Its ultra-small bore diameter of 0.04" and lightweight construction (0.0001 kg) are ideal for miniature mechanisms and precision instruments where space and weight are critical constraints.

D/W R09 R Bearing Structural Features & Performance Benefits
- Flanged Design for Easy Installation: The integrated flange on the outer ring (Flange OD: 0.17098") ensures precise axial positioning and simplifies bearing housing design, reducing assembly time and cost.
- High-Precision & Stability: Built to P0 tolerance class with tight bore and outside diameter tolerances, this bearing guarantees consistent running accuracy and minimal vibration, which is crucial for precision applications.
- Corrosion-Resistant Construction: All components, including rings, balls, and cage, are made from stainless steel, offering superior protection against rust and corrosion in harsh or washdown environments.
- Open Seal for High-Speed Operation: The open seal type minimizes friction, allowing the bearing to achieve a high limiting speed of 150,000 rpm. This makes it suitable for very high-speed spindles and miniature motors.
- Standard Radial Internal Clearance: The CN clearance group provides optimal performance for most general applications, ensuring smooth operation without excessive play or preload.
D/W R09 R Bearing Typical Application Areas
- Miniature and Precision Motors: Ideal for small DC motors, stepper motors, and coreless motors used in drones, medical devices, and robotics.
- Instrumentation and Control Systems: Used in encoders, sensors, gauges, and other precision measuring equipment requiring high rotational accuracy.
- Small Mechanism Drives: Suitable for office automation equipment, small pumps, and textile machinery where compact bearing dimensions and reliability are key.
- Medical and Dental Handpieces: The stainless steel construction and high-speed capability make it a fit for sterilizable medical tools.
