Precautions for Handling
International Standard Compliance
Intro-10
5. 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 a 50mm 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.
6. Do not attempt to have rods collide with an obstacle at high speed.
This may damage the coupling or other mechanical parts.
7. Grease has been applied to the outer periphery of the rod for the rod type.
Protect the peripheral equipment if grease adhesion negatively affects them.
8. In some conditions of environment of use, postures of installation and
conditions of operation, the base oil separated from the grease may come out
of ROBO Cylinder.
It is recommended to have a protection in case the peripheral devices could
get influence of the base oil.
International Standard Compliance
The ROBO Cylinder complies with the following overseas standards.
