2. Use a brush to work grease in to the roller screw
assembly. Be sure to cover all the threaded surfaces of
the screw assembly. This can be accomplished by
applying grease to a few places on the roller screw
assembly and rotating the components repeatedly in
both directions to work the grease into the assembly.
3. Force grease into the front of the thrust bearing
assembly. Make a concerted effort to insure that the
grease is well worked in. Grease must reach the bearing
just behind the bearing that is visible as well. Use the
following amounts of grease for each size roller screw
and bearing:
Tritex 60:
0.5 in
3
Tritex 75 & 90:
0.75 in
3
Tritex 115:
1.0 in

Reassembly
1. Rethread the roller screw into the internally threaded cylinder
(ITC). It is a multiple start screw, and this is not always easy.
DO NOT FORCE THE ROLLER SCREW INTO THE
CYLINDER. It is best to have the actuator vertical with the
open end of the roller screw cylinder facing up. Position the
roller screw above the cylinder so that it is aligned axially
with the ITC. Slowly turn the roller screw 1/4 to 1/2 a turn
counterclockwise with it in contact with the ITC. This will help
to align the threads on the roller screw with the threads in
the ITC. Rotate the roller screw clockwise and it should
begin to thread into the cylinder. If it does not turn freely,
remove it and begin again. When threading the screw into
the cylinder, it will roll freely into the actuator. When it
reaches the portion of the cylinder that contains the motor
magnets, the roller screw will be more difficult to turn
because of the magnetic field of the magnets. THIS IS
NORMAL. Continue to thread the roller screw into the
cylinder. When it reaches the bottom, it will become difficult
to turn and the motor and bearings will begin to rotate with it.
The roller screw is now fully inserted into the cylinder.
2. Place a small amount of seal lubricant on the inside surface
of the seal/bushing assembly.
