In Zen Buddhism, an ensō (literally translated in Japanese as "circle") is a circle painted by hand in one or two swift, fluid, and uninhibited brushstrokes. It is characterised by a minimalism born of Japanese aesthetics. No two alike, each expresses a unique moment when the mind is free to let the body create. It evidences the character and the context of its creation. The ensō symbolizes enlightenment, strength, elegance, the universe, and the void ("mu").
Bill Donakowski had these noble qualities in mind when he conceptualized and patented the world's first hubless caster. Trained as an architect and engineer and having worked extensively in the development of mechanical components for aerospace use, including for NASA and the space shuttle as well as commercial products, he found it remarkable that furniture casters hadn’t evolved in decades.
Bill presented his concept to Oconomowoc Manufacturing (OMCO), an experienced US manufacturer of custom wheels, and together they realized the design and production of a caster that is clean and purposeful - a striking yet simple design that is consistent with both the form and function of modern furniture. Today, Enso is a wholly owned subsidiary of OMCO. While others have since emulated the aesthetic, none are remotely as capable with respect to performance and load capacity due to the patented OMCO bearing design.
