The end cap houses the feedback device. Alignment of this
feedback device to the phases of the motor is critical to the
operation of the system. Extreme care should be taken when
removing the tie rod nuts or tie rods so as not to twist or pull on the
end cap of the actuator. Some feedback devices are sensitive to
movement of their mounting surface once installed and can be
damaged if care is not taken.
4. If your actuator does not have a front flange, skip this step. Slide
the front flange forward and off the actuator. The tie rods will
remain attached to the front flange.
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 to arrange for maintenance of a
preloaded screw actuator.
5. When the face plate is removed, the thrust bearing and the open
end of the roller screw internally threaded cylinder (ITC) are
visible. The roller screw can be removed by turning it counter
clockwise and threading it out of the cylinder. It may be
necessary to keep the roller screw cylinder from turning to
remove the screw.
4.2 Lubrication Maintenance
Grease lubricated units will require periodic inspection and renewal of
the bearing and roller screw grease. The table below shows the
recommended grease renewal period.
