• Attach an oil seal and plugs for the tapped holes for injecting/draining grease to the case Step 6
installation component.
• Align the mounting holes of the reduction gear (case section) with the positions of the tapped holes of the
case installation component, and then attach the case installation component to the reduction gear.
• Take extra care so that the O-ring is not caught by the mating section.
• Confirm that the centering shaft of the reduction gear (case section) is correctly fitted into the
centering hole of the case installation component.
• Check that there is no foreign matter adhering to the mounting surface.

If the O-ring is caught by the mating section, 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.
The installation orientation and necessity for
installing the deep groove ball bearing, oil seal, and
plugs for tapped holes for injecting/draining grease should be
determined depending on the customer's equipment.
• Using the hexagon socket head cap screw and serrated lock washer for the hexagon socket head Step 7
cap screw, tighten each component.
• Be sure to tighten the hexagon socket head cap screw with the specified tightening torque.
• Attach the deep groove ball bearing for supporting the input gear to the case installation
component.
• Check that there is no foreign matter adhering to the mounting surface.
(Reference: “4.2.3. Reduction gear mounting bolts”, “4.2.4. Serrated lock washer for hexagon
socket head cap screw”, and “5.1. Bolt tightening torque”)

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.
