1-4 WARRANTY
Seller warrants its products to be free from defects in material and workmanship under normal and proper use in
accordance with instruction of seller for a period of one year from the date of shipment to buyer. Seller's liability
under such warranty or in connection with any other claim relating to the products shall be limited to the repair, or
at seller’s option, the replacement or refund of the purchase price, of any products or parts or components thereof
which are returned to seller freight prepaid and which are defective in material or workmanship. Products or parts
or components thereof, which are repaired or replaced by seller, will be returned to buyer freight collect. This
warranty is not intended to cover consumer products, as defined in the Magnuson-Moss Warranty-Federal Trade
Commission Improvement Act, 15 U. S. C. Sections 2301-12, which are purchased by buyer for purposes other
than resale. If buyer is not intending to resell the products, and if the products are consumer products as defined in
the Magnuson-Moss Act, the foregoing warranty, but not the limitation of seller's liability, shall be null and void.
EXCEPT AS EXPRESSLY STATED ABOVE, SELLER MAKES NO WARRANTY, EXPRESS OR IMPLIED,
WHETHER OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE OR USE OR OTHERWISE,
ON THE PRODUCTS, OR ON ANY PARTS OR LABOR FURNISHED DURING THE SALE, DELIVERY OR
SERVICING OF THE PRODUCTS.
1-5 PRECAUTIONS OF USE AND INSTALLATION
1. Mechanical stops, if provided on the Electric Cylinders, (ECB), are only auxiliary devices to limit the travel of the
lifting screw. Engaging a mechanical stop during electric cylinder operation can cause damage to the internal
mechanism.
2. Travel can be limited using optional limit switches. The customer is responsible for setting these limit switches.
Inmost applications, factory or manufacturer-assisted installation is not required. However, it is necessary that
appropriate, qualified personnel perform the installation of Joyce/Dayton products.
3. Joyce/Dayton Electric Cylinders, (ECB), are not rated for shock-loading, extreme vibration or critical speed
conditions. It is the responsibility of the user to ensure these conditions are not imposed on the actuator or the
power transmission equipment. Contact Joyce/Dayton for technical assistance.
4. If service or maintenance is required, the load must be secured or removed before any work can begin.
5. The Electric Cylinder (ECB) can be mounted and operated in anyorientation. When used in a horizontal
position, the worm should be mounted parallel with the horizon and below the gear to ensure proper lubrication.
In addition, the length of allowable rise may differ for vertical and horizontal applications. Check the catalog and
this manual for allowable rises.
6. Standard Electric Cylinders, (ECB) have vents in the protection tube (outer tube). Additional holes will
be plugged. Properlyplug or vent holes to prevent dirt or moisture form contaminating the actuator.
7. Never allow the Electric Cylinder to retract beyond the minimum closed position or extend beyond the maximum
open position, as damage to the unit can occur.
8. External temperature may exceed 230 Degrees F. near maximum duty cycle. Use caution to prevent personal
injury.
9. Do not use in applications where Electric Cylinder can be jammed against an immovable object.
10. A brake motor is required on Ball Screw Electric Cylinders that have efficiencies greater than or equal to 30%.
This prevents the load from drifting when power is off.
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 Electric Cylinder (ECB) meetsor exceeds the load.
4. The Electric Cylinder (ECB) must be mounted on a rigid structure which is sufficient to support the maximum
possible load. The structure must be rigid. 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.
6. In systems with shafting, miter boxes, etc., confirm that the shafts and jacks operate without binding or
excessive force before powered drive devices are engaged.
7. When fastening the load to an Electric Cylinder, 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

pg. 4
side to make connection with your structure. Fully extend the Electric Cylinder to makesure the load is aligned
with the translating tube.
8. All Electric Cylinders are to be mounted with S.A.E. Grade 8 bolts or equivalent.
9. Torque the mounting bolts in a systematic pattern to avoid damage to the actuator.
10. Shaft and coupling guards are the responsibility of the user.
11. Optional limit switches, which maybe furnished with the Electric Cylinder, are NOT pre-set. Theyrequire field
adjustment before use.
SECTION II
MAINTENANCE
2-1 LUBRICATION
Electric Cylinder
1. Electric Cylinders are lubricated before leaving the factory.
2. Donot operate Electric Cylinders without lubrication.
3. For normal operation, Electric Cylinders should be greased at least once per month. Under extended use,
grease twice monthly or as conditions dictate. Grease with Mobil XHP 461 through the fittings on the Housing
(1) and on the protection tube (21). This is a No. 1 Consistency Grease. It is the responsibilityof the user to
maintain sufficient lubrication to the electric Cylinder.
4. The products listed below are recommended bythe lubricant manufacturers to meet the requirements for
normal operation. The listing of brand names is solelyfor the convenience of users of Joyce equipment and
their lubricant suppliers; it does not constitute anyendorsement. Joyce/Dayton assumes no responsibilities for
the quality, performance or availability of anylisted products

([e-mail]).
Gear Reducer (Option)
1. Standard ComDRIVE Electric Cylinder Gear Reducers are lubricated with AGMA 7 compounded oil (ISO Grade
460) before leaving the factory.
2. The products listed are recommended by the lubricant manufacturers tomeet 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 anyendorsement. Joyce/Dayton assumes no responsibilities for

3. Synthetic Lubricants are recommended for severe service applications. These lubricants offer more stable
viscosityand temperature properties. They have a longer service life and may require less frequent lubrication
changes. They also decrease friction and wear on the gear reducer and may increase the life of the gear
reducer.
4. This synthetic lubrication is also compatible with nitrile seal material as well as with alloy bronze gear material.

practice standards for safety.
Direct Drive Option and ComDrive Option
1. Motors supplied with Direct Drive and ComDRIVE units are not user serviceable.
2. Loosen the bolts attaching the motor to the electric cylinder or to the gear reducer and remove the motor.
3. The gear reducer on ComDRIVE units must also be removed before the electric cylinder can be disassembled.
Limit Switch, Encoder, or Potentiometer Option
4. Loosen the bolts holding the limit switch, encoder, or potentiometer and remove from their mounting bracket.
5. Loosen the bolts attaching the mounting bracket to the electric cylinder and remove
Disassembly of Ball Screw ComDrive (ECB)
6. Loosen the hex head screws on the worm bearing caps or remove the mounting adapters described above.
7. Remove the worm bearings and remove the worm shaft through the end of the sleeve. This may also be
removed after the Translating Tube and Screw Assembly is removed later in the process.
8. Extend the translating tube assemblya few inches. This positions the components to be more easily
disassembled.
9. Loosen the setscrews at the base of the protection tube.
10. Unthread the protection tube and pull it off over the end of the translating tube assembly.
11. Loosen the set screws that secure the sleeve cap. Unthread the sleeve cap and remove it.
12. This will allow the translating tube assembly along with several internal components to be pulled up out of the
sleeve.
13. Remove the retaining ring located at the base of this assemblyand remove the key.
14. Remove anyportion of the lower bearing that may be attached to the worm gear nut.
15. Unthread the worm gear nut from the lifting screw.
16. The upper thrust bearing can now be separated from the worm gear nut along with the seal.
17. Remove the grease from the cavity and inspect parts for damage or wear.
18. Assemble replacement components by carefully reversing the disassemblyprocess.
