D/W R4-2Z Bearing Product Overview & Core Advantages
The D/W R4-2Z is a single row deep groove ball bearing engineered for high precision and reliability in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads, while the shielded (2Z) design on both sides retains factory-applied grease and protects against contamination, ensuring long service life with minimal maintenance. This compact and robust bearing is ideal for applications requiring smooth operation and consistent performance.
D/W R4-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| D/W R4 | Indicates the bearing series and size designation in inch units. |
| 2Z | Signifies that the bearing is shielded on both sides. This provides effective protection against contaminants while retaining lubrication. |
D/W R4-2Z Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: Manufactured from stainless steel rings, balls, and cage, this bearing is suitable for environments where corrosion is a concern, offering enhanced durability.
- Effective Sealing: The non-contact shields (2Z) protect the internal components from dust and other particulates, significantly extending the bearing's operational life by preserving the grease integrity.
- Precision & Reliability: Built to P0 tolerance class and standard CN radial internal clearance, it delivers consistent performance and smooth running for a wide range of applications.
- Pre-lubricated for Immediate Use: Factory-filled with grease, the bearing is ready for installation, simplifying the mounting process and ensuring immediate, reliable operation.
D/W R4-2Z Bearing Typical Application Areas
The D/W R4-2Z is ideally suited for a variety of precision instruments and machinery, including:
- Precision Medical Devices and Dental Handpieces
- Small Electric Motors and Encoders
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Systems
- Food Processing Equipment (benefiting from its stainless steel construction)
