W 617/3 R Bearing Product Overview & Core Advantages
The W 617/3 R is a metric miniature deep groove ball bearing designed for compact applications requiring high precision and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. As a single row bearing with an open design, it is optimized for high-speed operation and is primarily intended to support radial loads. Its small bore diameter of 3 mm and integrated flange facilitate easy mounting and secure positioning in confined spaces, making it an ideal choice for applications demanding high rigidity and minimal space.
Model Code Breakdown
