Linear Actuators

Maintenance
Lubrication:
The only lubrication required for the linear actuator is the lead screw assembly. Lubricate the lead
screw after every eighteen months of operation. Apply a small amount of white lithium grease to
the lead screw.
Recommended Grease:
Lubriplate # 730-1 grease
Available from: Lubriplate Division
Fiske Brothers Refining Company
Newark, NJ 07105
or
Toledo, OH 43805
Note: If other than the recommended grease is used, the lead screw and nut MUST be
thoroughly cleaned before applying the new grease. DO NOT mix greases.
Actuators with potentiometer feedback (MT, SF, HL, HF, HT, and UHT) - LUBRICATION:
1) Remove the actuator from the machine.
2) Extend the actuator to its Out end-of-travel limit.
3) Remove the three Allen nuts and end cap. Be careful not to damage the rubber seal.
4) Remove the barrel covering the lead screw.
5) Very lightly lubricate the lead screw with white lithium grease.
Caution: Do not over-lubricate the lead screw as this could bind the nut and lead screw.
6) Reassemble the actuator.
7) Retract and extend the actuator 20 times to distribute grease along the lead screw.
8) Reinstall the actuator and make sure the actuator shuts off before it reaches a mechanical
stop.
