W 61703 R Bearing Product Overview & Core Advantages
The W 61703 R is a single row deep groove ball bearing designed for compact applications requiring high precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its primary advantage lies in handling radial loads efficiently within a minimal cross-section, making it ideal for space-constrained, high-speed assemblies. The open design allows for versatile lubrication options and facilitates easy maintenance.
W 61703 R Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| W | Stainless Steel Bearing | Indicates rings, balls, and cage are made from stainless steel for enhanced corrosion resistance. |
| 61703 | Standard Size Designation | Defines the bearing dimensions: 17mm bore, 23mm outside diameter, 4mm width. |
| R | Flange on Outer Ring | Features an integral flange (24.5mm diameter) for simplified mounting and axial location. |
