8.1 Precautions for maintenance and inspection work

ce and Inspection
Caution
Never use fluorine-based grease.
Mixing with lithium-based grease not only reduces the performance of the grease, it
may even cause damage to the actuator.
The grease film may run out if the actuator performs return operation continuously over
a distance of 30mm or less. As a guideline, every 5,000 to 10,000 cycles, have
approximately 5 cycles of return operation over a
50mm distance or more to regenerate the oil film.
The ball screw or guide may be damaged if the oil film runs out.
Notice
● First, be sure to wipe off the old grease, and then supply new grease.
● The degradation speed of grease may differ depending on the operating
environment (temperature, humidity and ambient atmosphere).
It is recommended to shorten the grease supply period if the actuator is used
under poor environmental conditions such as high temperatures, high humidity
or dusty atmospheres.
● Also, it is recommended to improve the environmental conditions in case the
grease changes color notably due to poor operating conditions.
● Base oil may separate from the grease due to the mounting orientation or
operating conditions.
Base oil may also leak from the inside of the ELECYLINDER to the exterior
through gaps.
Check visually for oil drips when supplying grease.
● An ELECYLINDER stored for 6 months or more may suffer from grease
degradation.
Supply grease before the start of use.
