CAUTION: Please follow the "Application Hints" on page 158 to ensure accurate assembly.

NOTE: The allowable transmission forces are calculated according to JGMA Standards 401-01 and 402-01. All dimensions shown in the above table(s) are listed in millimeters unless otherwise specified.

NOTE: Due to a decarburization layer of about 0.5mm, the rectangular sufaces have less than the specified hardness.

NOTE: Because of the heat treated gear teeth, appropriate care must be taken when cutting the length.
