6903 is a Thin Section Bearing with a fixed cross-section for each series that does not increase as the bore diameter increases.
The use of small-diameter steel balls significantly reduces friction, improves rigidity, and provides good rotational accuracy, meeting the demand for compact, simplified, and lightweight rotating mechanisms in machinery.
