Greasing
Start of work inspection ○
3 month inspection ○
○(Rod sliding surface, Ball screw,
Whirl-stop)
Every 3 months thereafter
6 month inspection ○ ○(Ball screw, Whirl-stop)
Every 6 months thereafter
○(Ball screw, Whirl-stop)
*1 Grease the rod sliding surface when grease is insufficient at start of work inspection, or every
three month. When greasing, always wipe off old grease before supplying new one.
The base oil may be separated from grease, depending on the installation orientation and
operating conditions. Perform visual inspection for any occurrence of drip.
Caution: • An actuator after 6 months of storage may have caused a degradation of the
grease.
Supply grease before start using. [Refer to 5.6 “Grease Supply”]
• Degradation speed of grease may differ depending on the environment of use
(temperature, humidity and ambient conditions). It is recommended to shorten
the grease supply period if the actuator is used under a bad condition such as
in high temperature, high humidity or in dusty ambience.
Also, it is recommended to improve the environment conditions in case the
grease changes its color due to the bad condition of use.
