Confirm that the design of the prepared motor mounting flange conforms to the size and quantity of
the case mounting bolts indicated in the separately provided “Outer dimensions” drawings and
specification sheet. For the catalog products described in “2.2. Parts codes of catalog products”,
refer to the size and quantity of the bolts listed in Table 4-4 in “4.2.3 Reduction gear mounting bolts”.
If no tapped hole for injecting/draining grease is installed in the motor mounting flange, the lubricant
cannot be filled/replaced after installing the reduction gear.
Case installation component
Prepare the case installation component for the reduction gear. The component can also be embedded in
the motor mounting flange.
Confirm that the design of the prepared case installation component conforms to the size and
quantity of the case mounting bolts indicated in the separately provided “Outer dimensions”
drawings and specification sheet. For the catalog products described in “2.2. Parts codes of catalog
products”, refer to the size and quantity of the bolts listed in Table 4-4 in “4.2.3 Reduction gear
mounting bolts”.
After attaching the reduction gear, bring
the dial gauge in contact with the location
shown in the illustration and rotate the
output shaft of the reduction gear by a
turn. At this point, be sure that the
deviation in the gauge reading is 0.02
mm or less.
