D/W R1810 R-2ZS Bearing Product Overview & Core Advantages
The D/W R1810 R-2ZS is a single row deep groove ball bearing designed for high-precision applications requiring reliable performance in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle primarily radial loads efficiently, while the shielded (2ZS) design on both sides retains factory-applied grease and protects against contamination, ensuring long-term, maintenance-free operation. This makes it an ideal choice for applications demanding high reliability and cleanliness.
D/W R1810 R-2ZS Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| R1810 | The basic bearing designation, indicating a specific size series with a bore diameter of 0.3125" and an outside diameter of 0.5". |
| R- | Prefix often denoting a specific manufacturer series or a flanged design (as indicated by the flange dimensions in the specifications). |
| 2ZS | Signifies that the bearing is equipped with contact seals (ZZ) on both sides. The "S" suffix can sometimes indicate a stainless steel construction. This combination provides effective contamination protection and seals in the pre-lubricating grease. |
D/W R1810 R-2ZS 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 harsh environments, including those requiring washdown or exposure to certain chemicals.
- Shielded Design for Protection: The 2ZS seals protect the internal bearing components from dust and other particulates, while also retaining the lubricant. This contributes to a long service life and maintenance-free operation.
- Pre-Lubricated for Immediate Use: The bearing is factory-filled with grease, simplifying installation and ensuring immediate, reliable performance within its specified temperature range of -30°C to 120°C.
- Precision and Rigidity: Manufactured to P0 tolerance class with a CN radial internal clearance, this bearing offers consistent and precise running characteristics, suitable for applications with moderate speed and load requirements.
D/W R1810 R-2ZS Bearing Typical Application Areas
The D/W R1810 R-2ZS is ideally suited for a variety of precision instruments and small machinery, including:
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
- Small Precision Motors and Gearboxes
- Optical and Imaging Devices
- Office Automation Equipment (e.g., printers, scanners)
