Rotacaster 125mm Double (85A) polyurethane roller/- 18mm Keyed Bore
Built with the durability and ride quality of an industrial floor wheel, the multidirectional rotacaster is a high performance robotic wheel. The fixed orientation of its main wheel allows forward and reverse movement without fighting a swivel caster offset, while the peripheral rollers facilitate turning, rotational, lateral and diagonal movement. When navigating turns this also eliminates all skipping associated with fixed wheels.
Its unique construction makes it the toughest, smoothest and fastest robotic wheel on the market with a choice of polyurethane or TPE rollers for outstanding durability and traction.
