50. tors are deployed involve high speed and high cycle rate with high acceleration high force or a combination To provide cooling of the motor within the GSX actuator for operation at the elevated current levels needed to perform these applications GSX actuators can be configured to be used with recirculated oil lubrication Using oil lubrication requires only low flow rates and low pressures to provide significant additional cooling There are several application and actuator configuration details that are involved in using a GSX with oil cooling and any application that will use oil cooling must be discussed with Exlar Application engineering so that the correct actuator options can be selected and the details of the application reviewed In linear actuator applications where high speed motion exists it is possible that the internal movement of the roller screw follower will act as a pump and create oil pressure higher than allowed Take care that the oil pressure is monitored during cycling If it appears that the pumping action of the actuator is causing spikes in the oil pressure it is recommended that the customer work directly with Exlar Engineering to determine if actuator configuration changes or application changes are required In all cases the reservoir in the lubrication system must be located below the level of the actuator to prevent the filling up of the actuator There is a high likelihood that over time as a result of seal wear and
