[Caution on Product Characteristics]
 For products with a tapped hole, a set
screw is included.
The allowable torques shown in the table
are calculated values according to the assumed usage conditions. Please see page
35 for more details.
The backlash values shown in the table
are the theoretical values for the backlash
in the normal direction for a pair of identical gears in mesh.
 If the bore size is less than Ø 4, the tolerance is H8. If the bore size is Ø 5 or Ø 6,
and the hole length exceeds 3 times of the
bore size, the tolerance is also H8.
 The use of S3T and S1T shaped set
screws for fastening gears to a shaft are
only applicable to light load usage. For

in combination.
