CAUTION: The bore tolerance is generally -0.05 to -0.1 but may be a positive value at the central portion of the hole.
CAUTION: Remachining the bore is not recommended since reworking material may expose voids.
NOTE: The allowable torques shown in the table are calculated using the Lewis formula. The backlash values shown are the theoretical values of a
pair of identical gears in mesh. All dimensions shown in the above table(s) are listed in millimeters unless otherwise specified.
