Rotacaster multi directional wheels are an Australian made and owned, patented design. Also known as omni-directional wheels, multi-directional wheels or holomonic wheels, Rotacaster omni-wheels are available in both a 125mm wheel diameter and a 48mm wheel diameter. Rotacaster omni-wheels are unique from other omni-wheels on the market because not only are they suitable for conveyor or inverted applications (e.g. ball transfer units and pipe rollers) but they are also suitable as a floor wheel (e.g on mobile furniture, hand carts and as wheels for hand trolleys). Rotacaster omni-wheels have a fixed mounting position and use rollers rather than a swivel mount to facilitate multi-directional wheels making them a new and unique alternative to the traditional swivel castor.
