W 602 Bearing Product Overview & Core Advantages
The W 602 is a metric miniature deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. As a single row radial bearing with an open design, it excels in handling primarily radial loads while offering high operational stability. Manufactured entirely from stainless steel, it provides excellent corrosion resistance, making it suitable for demanding environments. Its compact size (2mm bore, 7mm OD) and light weight make it an ideal choice for applications where space and weight are critical constraints.
