When sealing the section with an O-ring by preparing an O-ring groove on the
customer’s component
• Fit an O-ring into the groove.
• Align the mounting holes of the shaft installation component with the positions of the tapped
holes of the reduction gear (shaft section), and then attach the shaft installation component to the
reduction gear.
• Take extra care so that the O-ring is not caught by the mounting surface.
• Confirm that the centering shaft of the reduction gear (shaft section) is correctly fitted into the
centering location of the shaft mounting flange.
• Check that there is no foreign matter adhering to the
mounting surface.
If the O-ring is caught by the mounting surface, it could
cause leakage of the lubricant.
If there is foreign matter adhering to the mounting
surface, the mounting surface of the reduction gear may
be deformed. This could cause deterioration of
performance, such as abnormal noise and torque
irregularity, as well as reduced durability.
The shape of the shaft installation component may differ
from the illustration above, depending on the customer’s
equipment or shape of the reduction gear.
