Circular Mechanical Component Diagram - Engineering Illustration #2019935 (License: Personal Use)

This black-and-white line drawing depicts a circular mechanical part-possibly a bearing, washer, or seal-with three concentric rings and hatching to suggest material thickness or surface finish. The outermost ring features radial lines indicating curvature or machining marks, while inner zones use parallel strokes to denote different layers or tolerances. The style mimics traditional engineering drafting techniques used in manuals and patent illustrations.

Used in technical documentation, engineering textbooks, product datasheets, or CAD reference guides; serves users seeking visual understanding of mechanical assembly components or design principles.
