D/W R2-6 Bearing Product Overview & Core Advantages
The D/W R2-6 is a precision single row deep groove ball bearing designed for high-performance applications requiring exceptional reliability. Manufactured entirely from stainless steel, this bearing offers excellent corrosion resistance. Its open design facilitates high-speed operation, while the P0 tolerance class and controlled CN radial internal clearance ensure smooth and precise rotation, making it ideal for applications demanding high rotational accuracy and long service life.
D/W R2-6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer's prefix (D/W) |
| R2-6 | Specific bearing size designation in the inch series. |
| Open (No Seal) | The bearing is supplied without seals or shields, optimized for high-speed performance and allowing for custom lubrication schemes. |
D/W R2-6 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and stainless steel cage minimize friction and drag, enabling a high limiting speed of 80,000 rpm. This makes it suitable for demanding high-velocity applications.
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), this bearing is inherently resistant to rust and corrosion, ensuring reliable performance in harsh or wash-down environments.
- Radial Load Capacity: As a deep groove ball bearing, it is primarily designed to handle significant radial loads (82 lbf dynamic, 26 lbf static) efficiently.
- Precision Engineering: Manufactured to P0 tolerance class with a standard CN radial internal clearance, guaranteeing consistent running accuracy and low vibration.
D/W R2-6 Bearing Typical Application Areas
This versatile miniature bearing is ideally suited for a wide range of precision equipment and devices, including:
- High-speed spindles in dental and surgical handpieces
- Precision instruments and optical encoders
- Small motors and gearboxes
- Office automation equipment (e.g., printers, scanners)
- Radio-controlled models and drones
