The high torque to volume ratio available from a brushless motor, combined with the robust, high speed and high load capability of the planetary roller screw, make the Exlar line of linear actuators a true, all electric replacement for cumbersome high maintenance hydraulics. The use of electronic servo control provides simpler set up and more precise control than hydraulic systems as well.
Many amplifiers offer software that allows the entering of parameters or the downloading of "motor data files" that dictate how the feedback must be set up on the motor. Exlar can provide many of these "motor files" or the proper parameters to enter. Entering motor parameter data to some amplifiers may require assistance from the amplifier manufacturer.
2.5 Internal Holding Brake Many applications require the addition of the Exlar internal holding brake. The brake is held open by the supply of power to a magnetic/mechanical clutch. Whenever there is not power to the brake, the armature is held in place which prevents the inverted roller screw from turning and prevents the output rod from back driving, which in turn prevents the output rod from moving.

Because of this change in technology, Exlar now provides the transient suppression diode separately from the actuator, for inclusion in the brake control circuitry as needed by the end user. A schematic, shown below, is provided with the shipped product showing the typical use of the transient suppression diode.

For applications in which the load is free to rotate, Exlar offers the anti-rotation systems shown below. The drawings next page show the rod and bushing on only one side of the actuator. For long stroke actuators, the rod and bushing are required on both sides of the actuator.

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.
A schematic of a possible example oil system is shown below. Exlar Application Engineering can assist you in the development of your own oil system, or suggest pre-packaged oil circulation systems. The maximum allowable internal oil pressure for the GS/X Series actuators is 10 psi. Take care to insure that this pressure limit is maintained.
A GS/X Series actuator with the Side Mount option comes with threaded holes in the faceplate and endplate. Exlar recommends using hardened fasteners to mount a GS/X Series actuator to your machine frame. Exlar also recommends threading the mounting fastener into as much of the threaded hole in the actuator as possible, to prevent stripping out the threads in the actuator’s mounting holes.

For applications requiring this type of impact, contact Exlar application engineering to insure that the actuator is properly sized or provisions made to absorb the induced energy.
3.7 Manual Drive Operating Instructions Important: If manually driving through a brake or high force is necessary, please consult Exlar engineering. If a power tool is used to operate the manual drive the speed should be limited to 600 RPM An impact driver should never be used to operate the manual drive.
If your actuator has a preloaded roller screw, do not remove it from the cylinder. Preloaded screws require special tooling and procedures for proper disassembly and reassembly. Contact Exlar Corporation to arrange for maintenance of a preloaded screw actuator. Refer to the exploded view on the following page.
Remove the screws for the spline assembly and remove it from the roller screw cylinder. The RB option requires removal of the feedback device to access and Exlar should be consulted for assistance, or the unit returned to Exlar.
Be sure that the faceplate seats completely and squarely on the front of the actuator. The inner surface of the faceplate provides the pre-loading for the bearings, and it is important that it is properly seated. GS/X Manual.doc 02/17/14 PN: 10278 Exlar Corporation Rev. KK 952-500-6200...
A new main rod seal can be slid over the main rod, taking care not to touch the seal material to the threaded rod end. To have this service performed for you, contact Exlar Engineering or arrange with Exlar Returns Department to send your unit in for service.
