CAUTION: The tolerance of the side mounting holes (dimensions "E" and "F") are machined to general tolerances. We recommend that you secure the rack after assembly by means of dowel pins.

NOTE: 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.
