By contrast to conventional casters with “ball bearing configurations”, da caster sets itself apart through the use of a “sliding configuration” that does away with both axle and bearing. da caster consists of an aluminium casing, a roller and an inner ring made of a particular type of resin which makes it possible to create a ring-shaped wheel with a central hole. The result is a hubless caster with sufficient strength and stability that nonetheless appears to float.
Statement by the Jury
The extraordinary construction of da caster ensures excellent functionality and gives the caster its distinctive appearance.
