8.1 Precautions for maintenance and inspection work
8-2
8. Maintenance 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.
For Grease Option G5, do not attempt to use any grease that is not recommended.
The grease film may run out if the actuator performs return operation continuously
over a distance of 30 mm or less. As a guideline, every 5,000 to 10,000 cycles, have
approximately 5 cycles of return operation over a 50 mm distance or more to
regenerate the oil film.
The 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.
