D/W R2-5 R Bearing Product Overview & Core Advantages
The D/W R2-5 R is a precision single row deep groove ball bearing designed for demanding applications requiring high reliability and dimensional accuracy. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. This bearing excels at handling radial loads and is characterized by its compact flanged design, which facilitates simplified mounting and precise axial location within assemblies. Its open design and P0 tolerance class make it a versatile and cost-effective solution for high-speed, precision mechanisms.
Model Code Breakdown
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| D/W | Manufacturer / Series | Denotes the manufacturer's series for miniature and instrument bearings. |
| R2-5 | Size Designation | Specifies the bore (1/8" or 0.125") and the overall size series. |
| R | Flange | Indicates the bearing features an integral outer ring flange for easy mounting and positioning. |
D/W R2-5 R Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and making the bearing suitable for applications exposed to moisture, chemicals, or requiring washdown.
- Flanged Outer Ring: The integrated flange simplifies installation, prevents bearing creep, and ensures accurate axial location, reducing assembly time and complexity.
- High-Speed Capability: With a limiting speed of 95,000 rpm, this bearing is engineered for high-velocity applications. The open design and precision-ground components minimize friction and heat generation.
- Precision Tolerance (P0): Manufactured to ABEC 1 precision (P0), this bearing ensures smooth, quiet operation and minimal runout, which is critical for the accuracy of sensitive instruments.
- Radial Internal Clearance (CN): Features standard (CN) clearance, offering a versatile fit for a wide range of operating conditions and ensuring optimal performance under normal loads and speeds.
D/W R2-5 R Bearing Typical Application Areas
This bearing is ideally suited for compact, high-speed devices across various industries:
- Precision Instruments: Optical encoders, gyroscopes, and medical devices.
- Small Motors and Gearboxes: Stepper motors, servo motors, and miniature drive systems.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics: Joints and actuators in small-scale robotic arms.
- Aerospace and Defense: Guidance systems and instrumentation where reliability and corrosion resistance are paramount.
