4. In the event that service or maintenance is required, the load must be secured or removed
before any work can begin.
5. The Integrated Actuators can be mounted and operated in any orientation. Standard Ball
Screw Integrated Actuators have vents in the protection tube (outer tube). Additional
holes will be plugged. Properly plug or vent holes to prevent dirt or moisture form
contaminating the actuator.
6. Never allow the Ball Screw Integrated Actuator to retract beyond the minimum closed position
or extend beyond the maximum open position, as damage to the unit can occur. Refer to
Section 3-5 for travel limit information.
7. External temperature may exceed 230 Degrees F. near maximum duty cycle. Use caution to
prevent personal injury.
8. Do not use in applications where Integrated Actuator can be jammed against an
immovable object.
9. A brake motor is required on all Ball Screw Integrated Actuators.
1-6 General Installation instructions
1. Ensure that all personnel who will service or operate equipment are familiar with its use and
limitations.
2. Secure or remove the load before any installation procedures begin.
3. Be certain the rating of the actuator meets or exceeds the load.
4. The Ball Screw Integrated Actuator must be mounted on a rigid structure sufficient to support
the maximum possible load. An under-designed structure could lead to premature wear or
failure.
5. Drive shaft alignment is critical. Misalignment will cause reversing stresses in rotating
members and will lead to fatigue failure. Correct coupling specification is critical for systems
with more than one Integrated Actuator.
6. For systems with more than one Integrated Actuator, confirm that the Integrated Actuators and
shafts operate without binding or excessive force before power is applied.
7. When fastening the load to an Integrated Actuator, make sure the actuator is in the retracted
position. This positions the load accurately with respect to the lifting screw centerline. Never
pull the translating tube to one side to make connection with your structure. Fully extend the
Integrated Actuator to make sure the load is aligned with the translating tube.
8. All Ball Screw Integrated Actuators are to be mounted with S.A. E. Grade 5 bolts or equivalent.
9. Torque the mounting bolts in a systematic pattern to avoid damage to the actuator.
10. Optional limit switches, which may be furnished with the Integrated Actuator, are NOT pre-set.
They require field adjustment before use
Section II
Maintenance
2-1 Lubrication
1. Integrated Actuators are lubricated before leaving the factory.
2. Do not operate Integrated Actuators without lubrication.
3. The lifting screw and translating tube are lubricated with Mobilgrease XHP 221 grease, or
equivalent.
4. The housing is lubricated with Mobilgrease XHP 461.
5. Traveling Nut (TN) model ball screws should be lubricated with a spindle or 10-weight oil.
6. The products listed are recommended by the lubricant manufacturers to meet the
requirements for normal operation. The listing of brand names is solely for the convenience of
users of Joyce/Dayton equipment and their lubricant suppliers; it does not constitute any
