Orient the square flange toward the threaded end of the ball screw. Attach the retainer (15) to
the end of the ball screw using the screw and washer (16 and 17).
6. Thread the traveling nut (12) on to the ball screw (11). The flange of the ball nut should be
oriented toward the threaded end of the ball screw.
7. Insert the seal (18) and upper thrust bearing (2) into the sleeve cap (4). First, insert the seal,
then the bearing.
8. Assemble the key (13), worm gear nut (3) and retaining ring (10) to the end of the ball screw
(11).
9. Insert the above assembly into the actuator sleeve (1).
10. Thread the sleeve cap (4) into the actuator sleeve (1) and tighten.
11. Insert the worm shaft (6) through the sleeve (1) toward the flange. Inside the sleeve, this will
pass in front of the already assembled worm gear nut (3) and through the previously installed
worm shaft bearing (7).
12. Install the other worm shaft bearing (7) over the end of the worm (6). Seat this in place.
13. Install the retaining ring (8).
14. Check that the worm shaft (6) rotates when turned by hand. Adjustments to the stiffness of
rotation of the worm shaft are made by loosening or tightening the threaded connection
between the sleeve and the sleeve cap (4).
15. Spot drill through the threaded holes in the sleeve (1) and insert set screws (5).
16. Insert and seat the two worm shaft seals (9, 21). Exercise care so the seals are not damaged
on any sharp surfaces. Note: These seals are difficult to remove. Once they are removed, they
must be replaced.
17. Use the key (20) to attach half the coupling (19) to the worm shaft.
18. Attach the other coupling half (19) to the motor shaft.
19. Join the motor to the integrated actuator via the coupling. Align the motor mount holes to the
mounting holes on the flange. Use lock washers and screws (23, 22) to fasten the motor to the
integrated actuator.
20. Insert one pipe plug (24) into the sleeve and partially fill the cavity with Ronex Extra Duty 1
grease.
21. Insert the other pipe plug (24) in the sleeve.
