Abstract
A rotary rheometer having a magnetic thrust bearing. The thrust disk of the magnetic thrust bearing being situated between a pair of magnetic actuator assemblies and extending beyond the circumference of the actuator assemblies so as to encompass the magnetic flux lines generated by the actuator assemblies, thus minimizing likelihood of an undesirable preferential position or side load.
