The 16-65-XD is a caster designed to work in the medical field.  The ball bearing allows for easy movement and change of direction, and the soft Neoprene wheel allows for a very quiet roll no matter what load it is supporting.  The bright steel rig and center hub give this caster a very clean look, making this a great-looking, all-purpose caster for indoor environments. 16-65-XD Neoprene Wheel Swivel Caster
