Linear aerostatic bearings are frequently used in high precision stages for their advantageous bearing properties, with low friction and absence of stick-slip being most notable. To improve relatively low out-of-plane stiffness of air bearings, pre-loading is applied. A common method of pre-loading is by utilizing vacuum, where a constant vacuum...

An Integrated 6-DoF Lorentz Actuator with Gravity Compensator for Vibration / Precision Positioning has been analyzed and optimized. The gravity compensation function is realized by permanent magnets. The 6-DoF actuator is based on the utilization of the mover magnets. A demonstrator of the novel 6-DoF actuator integrated with magnetic gravity...
