D/W R6 Bearing Product Overview & Core Advantages
The D/W R6 is a precision single row deep groove ball bearing designed for high-performance applications requiring exceptional reliability and dimensional stability. Manufactured entirely from stainless steel, it offers superior corrosion resistance. This bearing is engineered to accommodate primarily radial loads and is characterized by its compact inch dimensions (0.375" bore), making it an ideal solution for space-constrained assemblies demanding high limiting speeds and long service life.
D/W R6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer/Series designation. |
| R6 | Specific bearing size code in the inch series. |
| Open (Seal Type) | No seals or shields, allowing for higher speeds and easy relubrication, but requiring a clean operating environment. |
| P0 (Tolerance Class) | Standard bearing tolerance per ISO standards, suitable for most general applications. |
| CN (Radial Clearance) | Normal radial internal clearance group. |
| None (Lubrication) | Supplied without lubrication, providing flexibility for the user to apply a lubricant suitable for the specific application. |
D/W R6 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and stainless steel cage provide excellent resistance to corrosion and are suitable for use in harsh environments and washdown applications.
- High-Speed Capability: The open design and precision-ground components contribute to a high limiting speed of 45,000 rpm, making it a true high-speed bearing.
- Radial Load Capacity: Engineered with a dynamic load rating of 555 lbf and a static load rating of 252 lbf, it reliably handles significant radial forces in compact spaces.
- Precision Ground: Manufactured to P0 tolerance class with tight bore and OD tolerances, ensuring smooth operation, reduced vibration, and precise rotational accuracy.
- Broad Temperature Range: Operates effectively within a temperature range of -30°C to 120°C.
D/W R6 Bearing Typical Application Areas
This bearing is ideally suited for applications where compact size, high speed, and corrosion resistance are critical. Key industries and equipment include:
- Medical and Dental Equipment: High-speed handpieces, pumps, and small motors.
- Precision Instruments: Optical encoders, gauging equipment, and laboratory apparatus.
- Food and Beverage Processing: Conveyor rollers and machinery requiring frequent washdowns.
- Small Motors and Gearboxes: Servo motors, stepper motors, and miniature drives.
- Aerospace and Defense: Guidance systems, instrumentation, and auxiliary units.
