D/W R3 R Bearing Product Overview & Core Advantages
The R3 is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. This bearing is engineered to accommodate primarily radial loads and is characterized by its compact flanged design, which facilitates precise axial location and simplifies housing design. Its open seal type and standard CN radial internal clearance make it a versatile choice for a wide range of industrial applications demanding high limiting speeds and operational stability.
Model Code Breakdown
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| R3 | Basic Bearing Designation | Specifies the inch-series, single row deep groove ball bearing with a flanged outer ring. |
| Open (No Seal Suffix) | Seal Type | No contact seals, allowing for higher speeds and easier re-lubrication. Requires a clean operating environment. |
| P0 | Tolerance Class | Standard (Normal) dimensional and running accuracy per ISO standards. |
| CN | Radial Internal Clearance | Normal radial internal clearance group, suitable for most general applications. |
D/W R3 R Bearing Structural Features & Performance Benefits
- Flanged Outer Ring: The integral flange on the outer diameter provides positive locating and mounting, reducing assembly time and cost by eliminating the need for separate locating components.
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making the bearing ideal for applications exposed to moisture, chemicals, or washdown environments.
- High-Speed Capability: The open design and precision-ground components contribute to a high limiting speed of 70,000 rpm, suitable for demanding high-velocity operations.
- Precision Ground Raceways: Ensures smooth operation, low noise, and low vibration, which is critical for precision instruments and sensitive equipment.
- Robust Load Capacity: With a dynamic load rating of 167 lbf and a static load rating of 56 lbf, this bearing is capable of handling significant radial loads for its compact size.
D/W R3 R Bearing Typical Application Areas
The R3 flanged ball bearing is ideally suited for applications where compactness, corrosion resistance, and precise location are paramount. Key industries and equipment include:
- Medical and Dental Equipment: Small motors, pumps, and handheld tools.
- Food and Beverage Processing: Conveyor systems and machinery requiring frequent washdowns.
- Precision Instruments: Optical encoders, gauges, and measuring devices.
- Small Electric Motors: Especially in corrosive or demanding environments.
- Office Automation Equipment: Printers, scanners, and copiers.
