  • Associated product(s)
In order to provide our customers more flexibility when installing servo gear motors in their systems, we have modified the design of torque arms for the plug-in version of 3-stage bevel gear units.


Sales release for the new torque arms is scheduled for May 1, 2016. Delivery release is scheduled for June 15, 2016.

At the same time, the old torque arms will be prepared for discontinuation, which will be announced in a separate information.

This modification only affects 3-stage bevel gear units.

Please note the following when converting the torque arms:

Design change

The design of torque arms of the versions KAD39, KAD49, KAD89 and KAD149 will be changed. The changes concern the dimensions d3 and l12, see graphic.

The exact dimensions are stated on the dimension sheets which can be downloaded via the DT Configurator.

Change of the Article No.

So far, the 14th digit of the article number of the plug-in version has been assigned the letter "D".

NEW: The 14th digit will be assigned the letter "D" with immediate effect. In order to keep the article number consistent, all plug-in versions of the 3-stage bevel gear units will be renamed.

An overview of the changes is shown in the following table
