Precautions for Handling
Intro-11
8. If return operations are continued over a short distance, they may
rapidly degrade the film of grease.
Continuous return operation within a distance less than 30mm may cause the grease film to degrade
rapidly.
As a guideline, in every 5,000 to 10,000 cycles, have approximately 5 cycles of return operation over
the full stroke distance or more to regenerate the oil film. Continued use of the actuator in that state
may lead to breakdown.
In extreme cases, flaking may occur on the guide or ball screw.
9. Do not attempt to have the rod or table collide with an obstacle at high speed.
This may damage the other mechanical parts.
10. Handling the spiral cover
The spiral cover is made by rolling a thin plate into a helix. Handle with care, as it will deform if
struck by a tool or pushed hard by hand.
11. Base oil may separate from the grease and leak from the inside of the
ELECYLINDER to the exterior due to the operating environment, mounting
orientation, operating conditions, etc.
Protect the peripheral equipment if base oil adhesion negatively affects them.
