• Align the tapped holes of the shaft installation component with the positions of the mounting holes Step 3
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 hole of the shaft installation component.
• Check that there is no foreign matter adhering to the mounting surface.
• Using the hexagon socket head cap screw and serrated lock washer for the hexagon socket head cap
screw, fix the shaft installation component to the reduction gear.


If an 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, which could cause deterioration of performance, such as abnormal noise
and torque irregularity, and 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.

If the hexagon socket head cap screw is not
tightened with the specified torque, the
reduction gear does not deliver the designed
performance. In addition, it could cause injury
and damage to the customer’s device and the
reduction gear.
